@@wal I agree with more of this style sub review. I've been looking at the NVX QBUS10P (10") as well, since I have a few of their marine amps on our boat that do a Great job! Thanks for all you do.. Great work.!. 😎
I’d ask for a review of the Kenwood KSC-SW11. It seems to be a very popular unit. Not high-rated (150W) but I have found it helps greatly in my Miata (2-seat convertible). Also doesn’t go under the seat 😅
Yeah, I have the Pioneer TS-WH500A HVT in the wife's car and it is underwhelming. I am curious how it compares to others and if they are all about the same or if some got mo bumps doe.
didnt expect a world beater at that price point, it does serve a purpose, cheap sub upgrade for a factory stereo, check! best car audio channel on youtube, hands down 💯
In 2019 I made a custom under seat subwoofer for my 2018 KIA Niro. I built a custom sealed box that ended up with about 0.35 cubic feet. The sub I used was a 10” Cadence shallow mount 2 ohm subwoofer. The amp was a cheap Walmart Razor mono amp. Total cost for everything was about $200. The sub had INCREDIBLE output down to about 30 hz. Anything below 30 hz rolled off VERY quickly and was just not useable. With that being said, the tight thumpy bass was AMAZING!! The bass was easily felt in your chest and it mixed really well with the stock speakers without overwhelming them, unless you cranked the bass knob! I ran this setup for 3 years until I sold the car. The best part of this setup is it did not take up ANY cargo space but still filled in the low end pretty good.
@@dannydennis318 you have to get creative in modern vehicles. For example, with the vehicle that I mentioned, a 2018 KIA Niro, it was VERY limited on the height due to brackets for power seat motors as well as a big vent to blow air in the back seat area. The vent pulled out VERY easily. I cut the brackets for the power seat motors out since my car had manual seat controls. Behind the back seats in pickup trucks can be EXTREMELY tight. I’ve seen videos on Ram 4 door trucks of people removing the sound deadening behind the back seats and thus gaining an extra inch of depth. One could build a custom box utilizing materials that are not ordinarily used to take advantage of all of the air space and depth available. I’ve also seen risers available for seats that raise the seats up slightly to give more room. You have to get creative, but possibilities do exist.
@91CavGT5 Yes I got creative in my 2022 Ford Maverick I found a guy that made boxes Ford up north that gives it .6 ft so I bought a 10-in Sundown classic that's okay with 0.5 for sealed I'm running out with a Stinger 1000.1. It is 1,000 RMS at 1 ohm. Before I do this I just had a Rockville 10-in powered sub behind the back seat and it sound pretty good up to about 60% volume. But I wanted more. Armoring the Highline Stadium JBL mids and Tweeter pack in the front called 62 CF what the JBL Apex 1502 for those which is 125 a chan RMS. And everything is hidden and it'll surprise you for what it is. The main thing everybody needs to know and I know most guys know this the polarity has to be right along with the gains and crossovers.
@91CavGT5 it's not going to blow you away but it's pretty Crisp And it hits pretty solid. I put a NVX combo base controller and voltmeter up front and so far it hasn't caused any problems with electrical system.
I literally installed two of these this weekend in my Mustang. They did NOT fit under the seats even with the seat all the way up. I ended up mounting them in the back seat replacing the rear seat cushion. They sound decent. They added exactly what I was missing in the factory system, a little bit of bass to even out the good highs and mids that the factory system puts out. They are nothing like I would have had when I was in my younger years but they deliver 200$ worth of bass in a small package.
Thanks for that review. I would love to see you do a video that compares a bunch of the same type of product, like under-seat subs (kicker, NVX, Rockville, JBL, etc.). Think like those tool comparison videos where they name the best table saw or whatever. Hopefully, you get enough subscribers and likes to make that possible. Always appreciate you efforts!
I have the Rockville 10 inch under seat subs behind the seats of my pontiac solstice. They hit decent for what they are. Would recommend for anyone who doesn't have the space for larger enclosures.
It would be cool to see a couple of other brands of these to see how they compare. It looks like the Kicker Hideaway is very popular. Call up your homies at Stillwater!
I didn't expect this level of video quality when it comes to talking and presenting information about an underseat subwoofer, you helped me to understand them better and more importantly, measure the real space under my seats 😁. All i want is to have something to fill the lower part of the sound because my car doesn't have a subwoofer and the 4 speakers sound quite clear imo, so it has nice detail but no base.
10:15 the 4 smaller TO220s are going to be power supply. 2 for rapid switching of the 12V input for the step up transformer. the other 2 TO-220s are going to be simple rectifier diodes, altho MUCH faster then your typical 1N4004 for example. im talking an *average* recovery time of 10 NANOseconds VS 1.5 microseconds. The last larger 2 is a TO-3P package and those are regular NPN and PNP BJT's for the class AB output. A pair of TO-3P's can safely do around 120-150W of output before heat dissipation in the package becomes an issue, so your test results closely match what i would have guessed if i seen the PCB before the tests were done BONUS: If you pause at 10:12 we can tell what components are which from the traces. the pair of TO220s on the right are the input switching to the low side of the transformer and the pair to the left are the rectifiers to turn the AC into pulsed DC which is then sent to the filter caps, when the feeds +/- voltage to the collector, or center pin of the TO-3Ps
The power output is quite impressive. Definitely, more than some of the other similar devices. I'm quite surprised to see a lack of glue around the amplifier. Typically on these type of devices, all of the large components are thoroughly glued down to prevent vibration damage.
It would be interesting to know if any "under-seat" subwoofers really make the grade. I have doubts due to their shallow nature to be able to compete with standard subwoofers. But those "bass thumpers" you can add to a seat seem a novel idea if you already have a subwoofer for your car. The brand with a weird name "Hyanka" seems to be decent entry level car stereo equipment. Which even entry level stereo equipment is better than 99% of OEM. You'd think $35,000 car would come with a good stereo from the factory. And still the answer is a resounding "No"! Thanks for the video.
The pre-fabricated ones won’t do much regardless of the brand. If you want an underseat subwoofer that actually has good output then you need to custom build one, but not squared off like this one. It needs to be contoured to your particular vehicle to take full advantage of all of the air space. I did this and it worked REALLY good.
I actually bought one of these very similar to the one you got. I put it in my dad’s d21 extended cab and it really did well. It wasn’t gonna blow you away but it did add bass and sounded great for 67$
I have a "Rockville RW8CA 8" 600 Watt Low Profile Under-Seat Active Powered Car Subwoofer" in my 1999 Toyota Sienna minivan, and it's surprisingly better than I had expected. It fills in frequency range the Orion 6.5 components can't produce. It doesn't shake the car or anything like that, but it nicely fills in some of the lower parts of the music.
I recently picked up the tiny pioneer ts-wx010a and *really* love it. Despite being a 6 x 3 sub, it's perfect for the scenario where you have replaced your HU, replaced your door and rear speakers, and need just enough extra bass without reworking your build. It fits so well mounted basically at the top of a footwell. It is comparative expensive for what it is. But at least for my uses I'm finding it really fits the bill for general sound quality for the above situation.
Ive had mine for about 6 months in my vw rabbit truck. Had just enough room to mount on my back wall between the seats . Its good for what it is im running 3.5s in the dash and 4x6s in the factory door locations with some old surface mount pioneers on an old school linear power 100w behind the seats it fills everything in surprisingly well for the small space i have to work with. It will fit under my seat but i need to modify a brace under the seats i been debating on getting a second one and relocating.
When i boughtmy vw camper one of the extras was massive box sub with built in amp .Space in vw is a bit tight , so took it pieces and rebuit it with ports relocated the amp then fitted speaker in box under seat ,works a treat .
Amp is a class AB design which is interesting, seeing that you can get pretty cheap but good class D designs that will give provide more power than that for less $$
@@JasonWW2000 Not convinced by that, especially as this is a discrete BTL amplifier design. You can get an 100W class D IC for a few bucks, just needs a bunch of passives added.
Honestly, I would go with one of those cheap mini-amps and a few transducers. This could even make for an entire series of videos "this vs that" style.
Installed a similar powered sub by kuerl in my 08 f150. Had to install it behind the rear seat. There is a void behind the back seat in the middle just big enough for these. With a couple upgrades to the door speakers, it sounds like a factory premium sound system. Definitely a upgrade, but not for competition.
Funnily enough, the spare tire sub that's attached to the Bose audio system in my 2020 Mazda CX-5 Grand Touring Premium does an excellent job of almost beating off the rearview mirror. The woofers in the doors vibrate the sideview mirrors pretty good too. I had a 2010 Mazda 3 Sport GT sedan that didn't have the Bose audio system or a subwoofer and I could've used one of these to add a little more low end.
Please please do more of these type enclosures. I’d love to add some bass to my truck but not needing anything big and crazy. Would love to see a shoot out between 3-5 brands
My friend got one of these but made by Infinity. I personally didn't like the sound because it was too high in the mid bass. A lot of thump but barely any bump (low 30Hz). I got in the EQ and dropped down from 500Hz to 125Hz by 3db to 5db and it helped the sub bass come out a bit more. Always drop frequency before adding it to mitigate distortion.
Love your channel especially on the xpr82d underdog dual amp and I love it when you do the throwback stuff from the 90s which is when I was in school but the problem I see time and time again with these compact Subs is there's just not enough air space to make any kind of real-world difference you know other than a little thump.. 🍺
my boss took that 4 dr 37 ford sedan . made it a 2 door suicide . pushrod 383 stroker with a paxton acc blower. countless years in custom shops grill specialist i didnt get a raise for 9 years. it is a beautiful car now . 10 grand just in paint. interior 5 grand. won many 1st place car shows in northern ca. i helped with stereo options . cant remeber what i suggested at the time.but it is a one off. im not talking for kent but somebody offered him 250,000 at a car show 20 years ago and he said no. let me know if your in that position. i dont talk for Kent but im sure it is way more less expensive now
I have the 8 inch blaupunkt underseat powered subwoofer it's in a metal enclosure it sounds pretty good . I recently unhooked it though I needed alittle more bass . I got a kicker comp 10in down firing sub and a nvx 500 watt mono amp . 500 at one ohm 330 at two ohms and 200 at four ohm's and I'm running at four ohm's it's a definite upgrade in bass but at more than twice the price.
Best under the seat powered sub I've heard is by infinity. Kinda expensive but definitely a more quality under the seat option. But still won't replace a bass system.
I just put one in my Crown Vic P71. I just leave it in the footwell of the back seat drivers side, I never have anyone sitting back there. It was very easy to add this and for my system, it rounds everything out and makes the car stereo sound really good. It's not a thumper. I'm going to use the hardware to attach it to a heavy plate of some sort to keep it from vibrating at certain resonances.
@@TheTray2003 would this set up work if mounted sideways on the right side of the trunk in the Crown Vic? I have an 02 LX HPP that could use a bass boost, but nothing crazy. I want to up grade my rear 6x9’s and put 3 ways in the doors. Finally, a double din unit for the head unit. Maybe a small amp to the bass if one is not built in. What do you think? I”ve done big systems going back to the 80’s. I’m old now and prefer good solid sound, but nothing crazy or car cutting fitament.
@@jonathandeere6232 The right side of the trunk is a good place. I'm thinking of making some sort of fuse block back there when I add backup camera, trunk light, etc. The subwoofer might need a simple plate to bolt to the area. It's not a banger of a woofer, though. It's good for me right behind the driver seat but way back in the trunk might sound thin and unimpressive.
this amp/sub is made under a ton of brands Kuerl, Kicker, Audiotek, Cerwin Vega, DS18, NVX, OWSOO, Hifonics, Kyanka, AF Audio, Adition, Pyle, Ugar, Soundfire, Rockville, Euphoria, Maxxlink, and 100's of other brands. This is a Chinese badge engineered branding company that sells this product to any company in their own label.
I have been using these for years. They do a pretty good job 3 days ago I installed a spare tire sub that I got off of AliExpress It's unbranded but it is identical to the Rockville Ghost sub The thing is bananas
For the F150, I had the same problem, just remove the "turd" bundle and remount after. I got 6 JBL fuse units in my supercab, 2 under seat and 4 on the wall, clean, stealthy and loud for what they are.
Right off the top I got a huge belly laugh; 20-180hz frequency response......but a 30hz subsonic filter. Comedy gold indeed.🤧 Not the one to give up storage space in my truck(which I use as much as the bed), I opted to add a second Kicker Hideaway since the first one proved to be decent in my previous truck with a smaller cab. They hit way better than they have a right to. Will they hit 20hz? Nope. I can do more than I expected at 25 if I sacrifice total output. If I wanted just 40HZ and above for generic rock etc It would be quite impressive. Maybe in the future I will work on some sort of custom enclosure to give me that 16-20hz range I want with some authority but for right now, for what these things cost? I am impressed.
I've been wanting to see a real test on one of these and/or a Rockville or something of better quality like the JBL Nano/Bass Pro and JBL Fuse which are not powered and have 2 8", these will fit under the seats of both my Square Body Dodge and Square Body Chevy. Thanks.
Anyone ever thought of using a couple of these ones to put either under your front seats , or directly in front of the seats, behind your feets. And then tune them to add midbass only, like 70hz to ~180hz? This to make a nice addition to frontsystem when having big woofers in the trunk.
ive had two of these in two different vehicles, and youre right its EXACTLY like the cheap crappy factory sub youll find in something like a chevy cobalt
Did you manage to measure the woofer impedance? Was it actually 4Ω? That speaker might actually do better in a slightly larger enclosure? Sure it's no Alpine shallow mount (and what a subwoofer that Alpine is!) but maybe if you bypass the internal amplifier and use a better amplifier it may do better.... I have seen similar products on marketplace and wondered if used directly wired to an external amplifier, might it actually be great for additional mid bass punch?
For me it looked like a good product until I saw that the electronic boards do not have protection against vibrations. Good videos colleague, greetings.
As someone else asked if you might be able to review more of these style of powered amps it would be appreciated. I personally am not to brand specific i am partial to JL but they are pricey. If i could find a good deal on one I would snatch it up. Ones I was looking at were Blaupunkt, MB quart, JBL, Phoenix Gold, Infinity, Alpine, Kicker. I was into car audio in its heyday and I know sadly brands that used to be front runners have fallen from grace. Still have my Soundstream Reference amps. Just looking for a good bang for your buck quality unit. I saw you did a Rockville tube one but them lying through their teeth about the out put is no bueno. Anyways, Thanks again. EDIT: I forgot MTX and Planet Audio. :) MTX Thunder used to be a beast. not sure how they are today though.
I mean playing through my shop system it sounded pretty good but that’s probably cause I’m using a 12 in kicker q in ported box lol. But for the price and if you can fit it and don’t want slamming bass not bad again . Also shout out to Big D Wiz for some clean ass vehicles 🚗 😂
What amplifier would you add to a stock 2018 chevy spark? I think the alternator is 60 amps lol so maybe a 350.1 skar? I wish mechman made a 300 amp alternator for my car so I could add a 15 or 2 12's.
Did you actually couple that to the car? Dean says these type of enclosures work best when they are coupled. For 120 bucks thats not bad for a little bump. Love Richard Pryor growing up.
If they put stereo digital amp and a dual coil subwoofer they would have the claimed 120W RMS for sure and also have better efficiency and lower parts count (cheaper to make).
For me this one is a pass, although I appreciate Hyanka offering a lot of their products at a low price and I believe the quality is good, this one is just a bit low powered. Hyanka please do an active subwoofer with a true 500 watts rms and sell it for $200 and I would buy that, it doesn't even need to be an under seat style.
Bought one about 2 years ago, didn’t last a year. I think the amp gave out. Little bump for the price , wish it lasted longer. Did fit well under a 2015 kia Sorento lx.
This one actually seems to not lie about its power as blatantly. I've seen reviews from other audio enthusiasts of similar types of subs(most of them made in the same factory and just with a different sticker) and it had an even weaker fuse that made it obvious. Same rear panel and also a woofer that isn't actually 10 inches. This one seems to be decent enough and even isolates electronics from vibrations. Unlike the worse ones I've seen. This one actually hits closer to 100W while the others had issues with 50W. But the super thin sub and tiny magnet just makes me think it's going to hit the bottom of the magnet really hard and really often. It is the same thing as the other chinese dropshipped things. But not as bad as the others.
As long as class D has been in use and refined, I would rather see one of these use a dvc sub on a TH8954 at 50-60v rail and get roughly 250 clean watts from it, along with better efficiency.
The sealed box doesn't help the output any, either. If you could find a solid 8" 2 ohm woofer that would work in a small enclosure like this, it might be something.
Lots of Sus comments today bro. Page get hit with bots? I know you wouldn't do that thing... Just strange. Not hating on yah bro! Thanks for the video!
I got a Rockville 10 inch under seat sub and it was the worst sounding thing I have ever put in a vehicle. Since I drive a regular cab truck I have limited room.

That's a pretty good demo, Big D. Everyone has their cheaper brands, and that actually shows in the construction of it.
How does it compare to other sub in a box under the seat set ups? Kenwood, kicker, rockville. Soundstream ect..
I haven't tried the other ones so I can't say definitively, but it's gonna be tough for a sub in such a small box to put out any real bass

@op8toolman same i have never heard someone use the name that way
I actually bought one of these very similar to the one you got. I put it in my dad’s d21 extended cab and it really did well. It wasn’t gonna blow you away but it did add bass and sounded great for 67$
I have a "Rockville RW8CA 8" 600 Watt Low Profile Under-Seat Active Powered Car Subwoofer" in my 1999 Toyota Sienna minivan, and it's surprisingly better than I had expected. It fills in frequency range the Orion 6.5 components can't produce. It doesn't shake the car or anything like that, but it nicely fills in some of the lower parts of the music.
I been looking at those I been trying to get shadow subs. To save up the trunk
Perfect timing! I've been looking at something like this for a mid fill on my daughters new car.
I recently picked up the tiny pioneer ts-wx010a and *really* love it. Despite being a 6 x 3 sub, it's perfect for the scenario where you have replaced your HU, replaced your door and rear speakers, and need just enough extra bass without reworking your build. It fits so well mounted basically at the top of a footwell.
It is comparative expensive for what it is. But at least for my uses I'm finding it really fits the bill for general sound quality for the above situation.
Always honest reviews from ya Big D, keep up the great work 💪
Ive had mine for about 6 months in my vw rabbit truck. Had just enough room to mount on my back wall between the seats . Its good for what it is im running 3.5s in the dash and 4x6s in the factory door locations with some old surface mount pioneers on an old school linear power 100w behind the seats it fills everything in surprisingly well for the small space i have to work with. It will fit under my seat but i need to modify a brace under the seats i been debating on getting a second one and relocating.
When i boughtmy vw camper one of the extras was massive box sub with built in amp .Space in vw is a bit tight , so took it pieces and rebuit it with ports relocated the amp then fitted speaker in box under seat ,works a treat .
Amp is a class AB design which is interesting, seeing that you can get pretty cheap but good class D designs that will give provide more power than that for less $$
Old model class AB amps like this are going to be cheaper than any of the newer class D style.
@@JasonWW2000 Not convinced by that, especially as this is a discrete BTL amplifier design. You can get an 100W class D IC for a few bucks, just needs a bunch of passives added.
@@ferrumignisIt's easy to verify.
Honestly, I would go with one of those cheap mini-amps and a few transducers. This could even make for an entire series of videos "this vs that" style.
Installed a similar powered sub by kuerl in my 08 f150. Had to install it behind the rear seat. There is a void behind the back seat in the middle just big enough for these. With a couple upgrades to the door speakers, it sounds like a factory premium sound system. Definitely a upgrade, but not for competition.
Funnily enough, the spare tire sub that's attached to the Bose audio system in my 2020 Mazda CX-5 Grand Touring Premium does an excellent job of almost beating off the rearview mirror. The woofers in the doors vibrate the sideview mirrors pretty good too. I had a 2010 Mazda 3 Sport GT sedan that didn't have the Bose audio system or a subwoofer and I could've used one of these to add a little more low end.
Please please do more of these type enclosures. I’d love to add some bass to my truck but not needing anything big and crazy. Would love to see a shoot out between 3-5 brands
My friend got one of these but made by Infinity. I personally didn't like the sound because it was too high in the mid bass. A lot of thump but barely any bump (low 30Hz). I got in the EQ and dropped down from 500Hz to 125Hz by 3db to 5db and it helped the sub bass come out a bit more. Always drop frequency before adding it to mitigate distortion.
Love your channel especially on the xpr82d underdog dual amp and I love it when you do the throwback stuff from the 90s which is when I was in school but the problem I see time and time again with these compact Subs is there's just not enough air space to make any kind of real-world difference you know other than a little thump.. 🍺
my boss took that 4 dr 37 ford sedan . made it a 2 door suicide . pushrod 383 stroker with a paxton acc blower. countless years in custom shops grill specialist i didnt get a raise for 9 years. it is a beautiful car now . 10 grand just in paint. interior 5 grand. won many 1st place car shows in northern ca. i helped with stereo options . cant remeber what i suggested at the time.but it is a one off. im not talking for kent but somebody offered him 250,000 at a car show 20 years ago and he said no. let me know if your in that position. i dont talk for Kent but im sure it is way more less expensive now
I have the 8 inch blaupunkt underseat powered subwoofer it's in a metal enclosure it sounds pretty good . I recently unhooked it though I needed alittle more bass . I got a kicker comp 10in down firing sub and a nvx 500 watt mono amp . 500 at one ohm 330 at two ohms and 200 at four ohm's and I'm running at four ohm's it's a definite upgrade in bass but at more than twice the price.
Best under the seat powered sub I've heard is by infinity. Kinda expensive but definitely a more quality under the seat option. But still won't replace a bass system.
I just put one in my Crown Vic P71. I just leave it in the footwell of the back seat drivers side, I never have anyone sitting back there. It was very easy to add this and for my system, it rounds everything out and makes the car stereo sound really good. It's not a thumper. I'm going to use the hardware to attach it to a heavy plate of some sort to keep it from vibrating at certain resonances.
@@TheTray2003 would this set up work if mounted sideways on the right side of the trunk in the Crown Vic? I have an 02 LX HPP that could use a bass boost, but nothing crazy. I want to up grade my rear 6x9’s and put 3 ways in the doors. Finally, a double din unit for the head unit. Maybe a small amp to the bass if one is not built in. What do you think? I”ve done big systems going back to the 80’s. I’m old now and prefer good solid sound, but nothing crazy or car cutting fitament.
@@jonathandeere6232 The right side of the trunk is a good place. I'm thinking of making some sort of fuse block back there when I add backup camera, trunk light, etc. The subwoofer might need a simple plate to bolt to the area. It's not a banger of a woofer, though. It's good for me right behind the driver seat but way back in the trunk might sound thin and unimpressive.
@@TheTray2003 Maybe I will upsize the woofer a bit to get the right bump. Good luck on your project and thanks for the reply.👍😀
@@jonathandeere6232 Good luck to you too! Take it easy...:)
this amp/sub is made under a ton of brands Kuerl, Kicker, Audiotek, Cerwin Vega, DS18, NVX, OWSOO, Hifonics, Kyanka, AF Audio, Adition, Pyle, Ugar, Soundfire, Rockville, Euphoria, Maxxlink, and 100's of other brands. This is a Chinese badge engineered branding company that sells this product to any company in their own label.
Marine grade one of these under seat all in 1 sub woofers???? Would love to see so I can find the right one for my golf cart. Keep them coming 😊
I have been using these for years. They do a pretty good job 3 days ago I installed a spare tire sub that I got off of AliExpress It's unbranded but it is identical to the Rockville Ghost sub The thing is bananas
Got a link?
How low can it realistically go though?
thanks for the feedback!
@@YusufGinnah 50 hertz maybe maybe... Definitely low and punchy
@@BlueDinnie 👍🏼 so it's definitely a consideration as a factory system add-on.
Thanks!
I like the new wheels brother, right on....
Those two big transistors are 2SD718/2SB688 and the little ones are MOSFETs
I used a JVC cs bb2 in my minivan 20 years ago definitely better than no bump at all!
yeah this one does ok for someone with no sub, but it sure isn't gonna shake your mirror or anything
For the F150, I had the same problem, just remove the "turd" bundle and remount after. I got 6 JBL fuse units in my supercab, 2 under seat and 4 on the wall, clean, stealthy and loud for what they are.
The larger transistors are the output transistors, probably 2sc5200/2sa1943
Hi big d wiz, please do more reviews on subwoofers. Enjoyed the video
Nice finally one of these, now do Walmart Power Acustic version to compare. and thanks for the video.
Right off the top I got a huge belly laugh; 20-180hz frequency response......but a 30hz subsonic filter. Comedy gold indeed.🤧
Not the one to give up storage space in my truck(which I use as much as the bed), I opted to add a second Kicker Hideaway since the first one proved to be decent in my previous truck with a smaller cab. They hit way better than they have a right to. Will they hit 20hz? Nope. I can do more than I expected at 25 if I sacrifice total output. If I wanted just 40HZ and above for generic rock etc It would be quite impressive. Maybe in the future I will work on some sort of custom enclosure to give me that 16-20hz range I want with some authority but for right now, for what these things cost? I am impressed.
please try Audison APBX 10 AS2 if it's worth the money, thanks always very interesting videos👍
Kudos to Hyanka for sending you one to review. Maybe it says something about the integrity of the company?
I think those dimples are to keep the sheet metal aluminum Ridgid so it doesn't vibrate. Metal buzzing from bass is a hell of a sound.
@@roberthaas80 its cast aluminum
Would Love to see you test out the Cerwin Vega Under the Seat Subs and your opinion on them ..
I have slang names for many common jobsite tools. The prybar is Richard, the sledge is Percy...
I've been wanting to see a real test on one of these and/or a Rockville or something of better quality like the JBL Nano/Bass Pro and JBL Fuse which are not powered and have 2 8", these will fit under the seats of both my Square Body Dodge and Square Body Chevy. Thanks.
Anyone ever thought of using a couple of these ones to put either under your front seats , or directly in front of the seats, behind your feets.
And then tune them to add midbass only, like 70hz to ~180hz?
This to make a nice addition to frontsystem when having big woofers in the trunk.
ive had two of these in two different vehicles, and youre right its EXACTLY like the cheap crappy factory sub youll find in something like a chevy cobalt
Good job D! I like that song!
Can you do a review on any of the slapz audio amplifiers? Been seeing them everywhere and they are cheap with no reviews or dyno tests. Thanks Big D.
Thanks for the suggestion
When I was growing up putting together car stereo equipment, amps were not allowed to advertise with such false information as they do today!
Great technical review! Please review these DIY amps: ZK-1002T Bluetooth 5.0 Amplifier Board 2.0 200W HiFi
Did you manage to measure the woofer impedance? Was it actually 4Ω?
That speaker might actually do better in a slightly larger enclosure?
Sure it's no Alpine shallow mount (and what a subwoofer that Alpine is!) but maybe if you bypass the internal amplifier and use a better amplifier it may do better....
I have seen similar products on marketplace and wondered if used directly wired to an external amplifier, might it actually be great for additional mid bass punch?
For me it looked like a good product until I saw that the electronic boards do not have protection against vibrations. Good videos colleague, greetings.
As someone else asked if you might be able to review more of these style of powered amps it would be appreciated. I personally am not to brand specific i am partial to JL but they are pricey. If i could find a good deal on one I would snatch it up.
Ones I was looking at were Blaupunkt, MB quart, JBL, Phoenix Gold, Infinity, Alpine, Kicker. I was into car audio in its heyday and I know sadly brands that used to be front runners have fallen from grace. Still have my Soundstream Reference amps. Just looking for a good bang for your buck quality unit. I saw you did a Rockville tube one but them lying through their teeth about the out put is no bueno. Anyways, Thanks again.
EDIT: I forgot MTX and Planet Audio. :) MTX Thunder used to be a beast. not sure how they are today though.
I am wondering how much is the speaker itself capable of. Maybe some tests with external amp?
I mean playing through my shop system it sounded pretty good but that’s probably cause I’m using a 12 in kicker q in ported box lol. But for the price and if you can fit it and don’t want slamming bass not bad again . Also shout out to Big D Wiz for some clean ass vehicles 🚗 😂
I had a similar stock sub in my 02 WRX.
that would surely fit under the old ford festiva seat.
What amplifier would you add to a stock 2018 chevy spark? I think the alternator is 60 amps lol so maybe a 350.1 skar? I wish mechman made a 300 amp alternator for my car so I could add a 15 or 2 12's.
please test anothers underseat wooofers brands...like: jbl, rockford, pioneer, nvx, kicker..etc...
😃
Would love to see you test the JL audio versions of these
Did you actually couple that to the car? Dean says these type of enclosures work best when they are coupled. For 120 bucks thats not bad for a little bump. Love Richard Pryor growing up.
Could you please do a dyno test on the Sony XM-GS100? Thnx so much!
If they put stereo digital amp and a dual coil subwoofer they would have the claimed 120W RMS for sure and also have better efficiency and lower parts count (cheaper to make).
Wow it has Zooka caps. You not old enough to remember those. They made my Kraco amps bang subs hard 😂
Hyanka make an amp you install into the enclosure for often sub $20 prices I've always been curious about if my house wasn't already too cluttered
Nice Toyota and Honda Cars 👌
i still have my old powered underseat amp i took the sub out its kinda funny how loud it is as a vocal driver
For me this one is a pass, although I appreciate Hyanka offering a lot of their products at a low price and I believe the quality is good, this one is just a bit low powered. Hyanka please do an active subwoofer with a true 500 watts rms and sell it for $200 and I would buy that, it doesn't even need to be an under seat style.
the most expensive part is shipping that thing from china to US and A
Lol @ Richard. That was a great reference BigD.
Bought one about 2 years ago, didn’t last a year. I think the amp gave out. Little bump for the price , wish it lasted longer. Did fit well under a 2015 kia Sorento lx.
hello can u do a video with VIBE blackdeath v3 15inch d2 i search for a video but i dont find any
Please do a review one the Orion cbt 3500x4
This one actually seems to not lie about its power as blatantly. I've seen reviews from other audio enthusiasts of similar types of subs(most of them made in the same factory and just with a different sticker) and it had an even weaker fuse that made it obvious. Same rear panel and also a woofer that isn't actually 10 inches.
This one seems to be decent enough and even isolates electronics from vibrations. Unlike the worse ones I've seen. This one actually hits closer to 100W while the others had issues with 50W.
But the super thin sub and tiny magnet just makes me think it's going to hit the bottom of the magnet really hard and really often.
It is the same thing as the other chinese dropshipped things. But not as bad as the others.
As long as class D has been in use and refined, I would rather see one of these use a dvc sub on a TH8954 at 50-60v rail and get roughly 250 clean watts from it, along with better efficiency.
Please review Sakura av2000 integrated amplifier please
Thanks.
Can they be ran in a pair or even 4 in like a Tahoe
I like the pun. It's funny as af. 😅
1:22 how you know my grandma had it there?! Evil audio wizard!😂
Maybe i try it on my Gmc Yukon
That Ford has a Love seat no fair😂
Wouldn't it help fitting under the seat if you remove your aftermarket floor mats. That lip is huge on those rubber mats
I was bummed when it didn’t fit the F150
The sealed box doesn't help the output any, either. If you could find a solid 8" 2 ohm woofer that would work in a small enclosure like this, it might be something.
Williston you talking bout a Richard tools scraper/pry

Fits on the ceiling
Lots of Sus comments today bro. Page get hit with bots? I know you wouldn't do that thing...
Just strange. Not hating on yah bro! Thanks for the video!
I got a Rockville 10 inch under seat sub and it was the worst sounding thing I have ever put in a vehicle. Since I drive a regular cab truck I have limited room.
