*** About This Video ***
In this video Dereck tests out the K9 series of subwoofers
One of these days mainstream companies will realize people have access professional grade instruments to call bullshit on inflated power ratings!!! 👍
Great collab, man!!!
You are SO right! Rockville has been a bit under the microscope, but I’d think they would be extremely cautious with their ratings. Oh well, maybe in the v3
Yes thats right guys 😊 i have a sub this is rating about 5kw rms but with 10kw it is not at the xmax and dont will be warm.. 😂 Ground zero GZPW 18 SPL.. see in my last video
One day
@@wal yes we will see it in v3 😂👍 i dont understand that ratings 5000 watts and 500 is the maximum... better Rockford Geound zero or oreon... ratings 500 watts and have no problem with 1kw.. the same if seen at the GZRW 30x spl D2 rating about 1500 watts i mean.. and 2 of this in series and paralell that is 2 ohms at the amp.. and 6kw was not a Problem for this guys for a pair of minutes... i think continues is 2,5kw and it is not expensiv...
Hell, honesty in a product can lead to more sales.
I’m a disabled combat veteran and a stay at home dad of a 2 year old who loves to ride around and listen to hip hop/rap. Currently we only have 2 Sony 6.5 3 ways in the front doors and 2 Sony 6x9s in a box that I built that’s in the extended area of my Frontiers cab. No amp just running off the head unit but I’m saving money to try to get us at least one 12” sub and an amp that’ll sufficiently power it. Love the videos bro.
I got an NVX 10IN, 400w amp & box for like $250. Still slams after 2 years
Steve Miller nice man. I actually found a blown Memphis Audio Power Reference 10” in the trash at a car wash a couple days ago. I’m gonna get the stuff to rebuild it so that should be pretty cheap.
@Aziryse really, you we have alot more important things to shield our children from. The news and product commercials are worse than rap. And all that kid knows is it has a cool beat.
@@erictheboringone5292 im sure you have but ignore that smug pos azirgse. Props for being a stay at home dad and having fun with your son while doing it
I bought a K6 12" sub and a power akoustic amp that the budget channel reviewed and it's been an incredibly loud set up. I love it. Completely massages my body when I crank it lmao
That’s what matters!!

25:19 Final Thoughts on the K9 and CEA/CTA Ratings
Williston Audio Labs , did you close your rear door on your sequoia
@@fredroehl157 yes, it was only open to show off the subs flexin'
Enjoy Your channel, keep up the good work. Like Rockville.
Did you tune individually for each sub or flat settings across and did you use a scope or dd1
Why doesn't adding more subs add decibel levels? I mean significantly adding boom.
You know how to make a Rockville K9 v2 handle a 4000Watt amplifier? Use a Rockville "4000Watt" amp! Hahahahahaa!
4000 Watts is 4000 Watts I doubt the brand makes that much of a difference.
@@nathanz602 There was a time when a Rockville amplifier displayed as '4000Watts' was not the RMS value - it was like HALF. 2000Watts is still good power.
Rockville k9 (15) got 4 on two Fosgate power OLD school amps 1100 @1 channel amp from 1999 steal banging.
$1000 each amp 👍🏽 ya boy👍🏽
I want a Rockville 10,000 watts amp👍🏽
Some good timing there. Just finished watching the exo video and this one popped up, glad I didnt pull the trigger on one of these last week. Especially now that the price went up 30 bucks on Amazon.
Price went up? I didn’t notice that 🤔
@@wal For me the only one you can buy on Amazon is 125 (was being offered on Amazon for 99 a week or two ago) and it's on a 1 month shipping delay.
@@wal That's for the w10k9d2 btw.
I can't believe how good this channel is. I am in my late 40's and i love seeing all the classic equipment. Your channel is very entertaining. Thanks for the content!
Thanks brother 👌
my rockville 10 inch sub does real well with 600 watts they just need to rate them right .
I like that you are wearing a HiFi Vega shirt, showing the love.
Thanks for the video, very informative. With your sacrifice we all gained a more realistic RMS rating for long bass sessions on these K9's.
I've had a k9 15 v2 for over 2 years and still slams. Wired to 2ohm with about 900rms no problems and it slams.
👌😬👍
@@wal lol
I got 2 of the 15's v1 in my at 1ohm with about 2000rms and they've been sounding good for the 2 years I've had them
I got the 25 dollar blaupunkt shown on this channel a few weeks ago and I can say it has been doing great for me. I am only pushing 500 RMS through it but the sound quality is fantastic.
Do you have a purchase link for this sub ?
Thanks for the feedback 👌
I have 2 of the punisher series in a ported qbomb box and it slams sumthin seriously.very happy would recommend these all day ...
thanks for being the only truth teller out there who doesn't sugar coat any brand of amps. and awesome job adding my boy EXO!! that guy is a nut!! love his build videos. keep up the great work and telling us the truth about these amps.
That Fred Sanford clip gets me EVERYTIME! 😂😂😂
I personally like Rockville's equipment, and I must say I'm impressed. I have a db55 in my car for some time now, rated at 2000watts rms 4000peek watts running four kenwood coaxial 150watts rims 300watts peek and a 12" Alpine sub 500 watts rms 1500watts peek. Works fine for me puts out some serious power and I'm actually thinking about getting 12 or 15 Rockville sub in the future. I enjoy watching your content btw, keep the videos coming!
Thanks for the feedback 👌
I want to see the same test done to subs from Skar or American Bass with no break in period and see what happens. The equivalent of their subs to the Rockville. I'm all about uncovering imposters in the car audio game and stand by the saying, "just put what it really does on the box and don't inflate the ratings". I'm old school and do the same thing as you Big D and one time a few years ago I bought two Boss Phantoms 10's for the heck of it to see what they do. Well I hate to say this but tell me why those $50 dollar subs lasted longer than some other subs I've owned! I say that to everyone to not hate on every single product because of a name. Don't get caught up in the business foolery. Yes there is crap out there but there is also good out there that doesn't break your wallet. I'm glad we have Big D, Budget Gem, and Meade to do dyno's for us!
So far my 20 dollar blaupunkt is still kicking and hasn't let out the smoke!
For the price difference I would go with 4 of those Blaupunkt.
I think I know what they did. Anyone that would be buying and running these would have no concept of impedance rise. So they are saying 1000 watts rms so the every day consumer that knows 0 about the technical side of audio will buy a 1000 watts rms amp. Which as we all know will get you maybe 600-700 watts peak after impedance rise which would probably put this sub around where it is actually rated 500-600 rms.
This is exactly what EXO and I discussed today and agree
thanks since i got into audio your channel has helped me immensly. I got my 5 channel based on your tests. The pioneer gm 9705. puts out 600 at 2 ohms 350 at 4, which is enuf for any subs I need in my small car. Thanks for the chance on the sub too. Hard to have a hobby on a lower budget.
Can u test the walmart gothic speakers I’m interested to see results 2,500 watts 🤔😏
The more inflated the ratings, the more budget bs the brand. MF's might as well just say infinite peak watts or 777777w peak.
They take like 850 1050 bamf will take 1200
Just mind blowing that Rockville themselves didn't do these tests before dropping them to the consumer.Just goes to show they only care about the quick dollar..Tyvm for putting out these quality vids Big D 🍺
I sure wish they would’ve lowered those ratings more 🤷♂️
I think its safe to assume if you bought a budget sub, cut the rms in half and run it like that. Its all marketing and has been marketing since the word go. Unless your willing to drop a metric ton of cash on high end stuff, under power your gear and live with a little less bumps for longer.
Yep 👍
Always watch your vids so i know what to buy....watching all the way from the caribbean...love your vids👍👍
Let's see you do some cheap skaraudio subs
I've honestly have never had any issues with the rockville line up. Ive maxed em and beat em up hard.. And still kicking.. Idk how I always miss these giveaways.. I watch the vids as soon as they come up...or I have time .. Absolutely love this channel Dereck!... Yeaaaa boooiiii!!!
Thanks for watching and commenting!
I know someone who blew his and ordered new coils and spiders and such from lord of bass and just used the motors and baskets from the k9s and they actually sound good and take the 1000rms now daily
The K9 got beat up but it’s actually a great sub if you don’t overpower it
I recently discovered your channel and I have to say it has become one of my new favorites. I love the fact that you test real world cheap stuff instead of the boutique high-end brands that only the wealthy and competition guys would care about. When I was growing up it would have cost at least 2 grand to get the performance out of a sound system that you could spend less than 500 for today. Generally speaking we are living in the Golden Age of car audio in performance vs cost if you can overlook the stigma of going cheap. I doubt the average listener is going to discertain the performance in 8/10s listening levels. It's the extra 2/10s where I think the high end brands have their place. Not only that, when you go cheaper, it hurts that much less when someone breaks in your ride and steals everything!
Keep up the great content and disturbing the peace!
Thanks for this insightful comment. I’d agree we are lucky to have access to such inexpensive products today! Thanks as well for the kind words!! 👌😬👍
Not bad ppl don't understand value they expect a $100 product to be like a $400 product
Interesting vid as usual! It's actually kind of amazing what you can get for "lo-dough" now days vs 30 years ago. These look like they beat the snot out of the radio shack 15's I had in my car back in the day, and with the prices adjusted for inflation, these are even cheaper!
Honestly if you're not purposely clipping the hell out of them they run fine.
Tell me about it!! The average person buying them don’t even listen to them that hard all the time! I love the testing though! Maybe they will stop putting 4000 watt stickers on 600 watt subs all day!
YES SIR!!! Still doing your thing, keeping US updated & saving US a lot of TIME & MONEY
I feel like its only the k9 subs. I see the k6 subs doing well. The k6 has a 5 star rating on Amazon with everyone saying great things. I haven't seen any videos of a k6 smoking
The k6 is so much better I have one and it actually takes near 600 rms with no issues
@@multigamer6394 cool man, good to hear that. I purchased 2 k6 subs despite everything I heard. I purchased a rockville rxd-t2 amp to push them. Big D wizz dyno it at 1050 rms @ 4 ohms. It should push them well.
So I've owned a pair of rockville k6 d2. I sold them 1 month later. They didn't smoke, but they did sound and smell like shit. They were in a Q power horn vented box. 4 cubic feet tuned to 32hz. Rockville rxd-t2 amp. Amp dyno at 1030 watts rms.
I have 1 rockford p3d2 12" that destroys the 2 rockville k6 subs. P3d2 is in a Q power vented box. 1.79 cubic feet tuned to 42 or 45hz. Pioneer 8601 dyno at 800 watts rms.
Just get 1 rockford p3 and dont look back. TRUST ME
Stick to "CEA" rating on the K6 and you should be fine. I've had a W10K6D4 on 450Wrms@2ohms for nearly a year now and it's banging right along. I knew damn well when I bought it that I wasn't getting a 1000W sub for under 70 bucks.
love your videos always nice to know what your really getting thanks
So if the glue and coil has been improved wonder why they still can't handle the power?? I seriously doubt rockville knows why.
Most likely cheap glue and/or too small of cooling hole on the coil former.
No More BS Please. I never thought of the former holes being to small. The glue does seem better.
I've actually been looking at get one of these for my wife's car cuz she just likes to have a little bit of extra bass you know not much I appreciate your reviews that's awesome of you want to buy one directly brand-new that's you're an awesome and appreciate everything you do
Thanks for showing me a brand to stay away from. A budget sub that I wouldn't mind see get tested that is quite popular. Is the Power Acoustik Mofos. Are they as good as the hype?
You've helped so many of us on our purchases and system configurations. Just want to say THANK YOU BIG D!!
Thanks for watching and commenting!
I used to be die hard MTX all the way but after experimenting with multiple budget brands I think Rockville may just be my go to. Just keep em at half RMS and don't clip em.
Im debating trying out the rockville K9 6.5 subwoofer, got a pair of skar evl65 and am impressed now I wanna try other 6.5 subs.
@@martinez1701a I've had a little over a dozen different 8's. Currently I have a pair of K9 8's in a cheap labyrinth box and they do well enough for me. I liked the Soundstream Reference 8's too, a step behind the K9 for same price range tho. Best bang for buck woofer I've found.
@@JesusSaves86AB Have you tried the skar ZVX8? Curious how it compares. I have 2 in my car but I have them underpowered right now.
@@c0c0asauce I have yet to try anything Skar but a buddy of mine has a ZVX15 and loves it.
Just go for Skar, AudioPipe, or American Bass , way better then Rockville and more then reasonable prices
I really dig that you are doing spl testing. Look forward to seeing more.
I know somebody hittin da 150’s for real 😳
Guess What? I bought one of the 2 ohm models after this video. and ran it @ 700 watts @ 4ohms for months..... no issue.... so i bought another one for 93 bucks that was refurbed from Audio Savings last week. which is one of Rockville's sister companies. I run the Bassrockers 2000watt RMS model 2000.1D amp which is in it's self a budget GEM @ 175 dollars for true rated power. I ran them with the subsonic set properly, 80hz crossover both of them wired down for a 2ohm load on the amp. so both subs seeing about 650 to 700watts RMS EACH! have had them in the car for 3 days, and I run them High for about 1 1/2 hrs everyday (back and forth to work) i check coil and amp tempts after every run... no heat.. no smoke... amp and sub dust caps cool to the touch. but as soon as i clipped them on purpose, you could smell them heat up a bit, they just don't have a huge margin for error ( i blame the CCAW voice coils). All rockville has to do is rate these 700-900 watts RMS and they would be fine, you could never touch 2000 watts on these things except maybe for a burp, and i'm leary of 1000 but will be trying it after the second sub finishes it's break in. once it's broken in like my first one, i'll run it down to 1ohm load on the amp and give it the 1000 watts per sub smack and see where it gets me!
Great feedback 👌
@@wal Big D, you're the reason I got the Bass bug again. all the old school amps brought me back to the old days when i was a kid and everyone in the hood had crazy setups. Keep it up! Hoping to win one of your giveaways one of these days lol.
Not a bad woofer at all! I'd feed it 500-750w RMS and call it a day. Excellent video, I'm glad they fixed the issue!
✌️😬
you talk to the majority of rockville buyers and they swear their subs have never blown. then you go on a car audio forum and everyone that has never used rockville will swear rockville blow.
Jorge Martinez i had 4 rockville k6 12’s on the rxd m4 never had a single problem with them in the year and a half I had them
I've had my k9 12s for almost 2 years on 3600 watts rms 1 ohm impedance no issues they sound great! Also depends on your style box I have a customized box at 20hz made out of granite slams!
@@asabovesobelow4414 hey bro, do you think the Rockville k9 is better than a audiopipe bd3 12?. Please give me your input.
4 cars with k6 subs from 10s to 12s never an issue beat so hard make the roof of the pole barn at work shake
Thanks Big D you always shed the light on these manufacturers. Keep up the good work.
Smokeville K9 Subwoofers
Awaome video as always. Big D
Lol i just watched exo
Two together almost an hour!!
The sound of that 12” poppin was gnarly bro.. best video yet.. woofer vids are more exciting than seein dyno numbers for sure.. love your channel none the less.. keep up the great work homie
I appreciate the feedback!
casually listen to PEB Bassgasm lol
It's just absoulety nuts how the technology has changed! Years ago I did a 143 in a mustang hatchback with two Phoenix gold Xmas 15s, powered by a 250m2, well over 1700 bucks in 1999,
The crazy thing is these subs likely aren't even broken in. Imagine when they are , they'll he able to handle more power and play it more efficiently
Really liking this for a budget for my wifes car shes really becoming a basshead😍😍
Literally have all Rockville stuff in my gfs car she is happy and shows off her bass to coworkers. She's happy I'm happy, we have blown up a two sets of v1 subs they sent us the v2s for free a few months ago so far so good. Rockville db15 and db45 for her subs and mains cheap kenwood 3 ways and dual Rockville 12s it sounds really good in her big ass challenger.
Rockville looks nice but that's about it...
I don't have hands/ears on experience with the K9s, but I do with K6s. The K6s have been solid. What I see as the problem with the K9s is just a marketing issue... It is a $100 woofer being pitched like it is a $300+ woofer...which will only lead to dissatisfaction to those expecting it to perform like a $300 woofer. For $100 though, it would be top of the heap.
Turn that sub around where the magnet is outside of the box so it can breathe!! You'd probably be surprised at how many top name subs you would smoke with that test!!! The Lanzar Max Pro and Hifonics Brutus subs caught my eye for bang on a budget woofers
Not to mention their not being broken In yet
Would love to see the Rockville Destroyer tested too! Great collaboration with Exo!!!!
Those look mighty beastly
Warm, stinky and smokes... sounds like my ex-wife
Ouch 😮
Great video, lasted longer than i thought it would.
If I won this sub I would sell it
Always good vids. Thanks Big D
I was watching this again and I noticed if I see correctly Rockville has there spider(s) glued to a bolt on ring... That's pretty cool. I'm actually surprised that that isn't used more along with a bolt down surround land. If the tinsels were removable to you could compleatly disassemble and reassemble you entire driver for inspection and repair... If company did this and sold recone kits with the ring already glued a person could compleatly rebuild a sub with nothing but an Allen wrench..... Plus be great for people like me that loooove to take stuff apart to fittle n see what makes it chooch...
On a side note...the $150 challenge thing goin around....one to check out.the grs 12" subs from parts express fer $20 each....i just tested a build i did.4 of em in 6 cu ft int. Sealed. It slams pretty good on 350 watts.
Good tip!
what they did is get a generic 300w coil and slapped it in and rated it at 4000w pmpo rating on it and said lets rate it at 1200 or somet and make an excuse so people still buy our proucts, like if they were to rate is at 300-600w then everyone would buy them and they would make business
yeah but still took 1000w untill it died so maybe dont drop 1kw to ur 90$ sub
A 3" coil with decent venting should easily handle more than 300w. (which it did)
I love this channel so much.... Derek seems like such a down-to-earth guy. He's just a good honest straightforward cool dude.... Props my brother.
Thanks man, I’m laid back and chill. No acting here! Thanks for watching and commenting!
Blowville
Guarantee 99% of the subs in this price range won't handle that power
Thanks for the video Big D! Cool to see you colaborating with EXO!
He’s good people!!
Yeah that sub isn't handling that much power. Look at the ohm load go up the coil is creating more resistance the hotter it gets. You were almost blowing it with that 1000 watt test judging by the resistance. I don't think it would have made it another minute. Looks like a 500/600 watt amp is about all you want to give them daily driving. That's not bad honestly. I don't think the low end Skars would put up a much better fight.
Skarbage sucks
All sub resistance goes up and down as they flex. If you hook up a meter and just push the cone down by hand the ohms change.
@@mlooman5488 skar is underated i can say the sdr are not underated and will blow and the rp 2000 lower bad sq other that skar is awesome ik someone who sent the evl 18s on a skar rp 4500 stinky the first time after break in no problem now they on an ( taramps 8k⬅ definitely will blow only send these up to 4k dont be fooled by the 1200 rms ) then u got the zvx send those 8k and u good and DNR send 2 of those 15k just asking why u think skar is garbage ? Had no problem with skar nice budget brand
Hooked up a friend's system. Running his 12d4 on JL AUDIO RD500. He only got this sub for something to listen to until he can afford a 12w6. It's still going and he's very happy with it.
Never had a single issue with anything Rockville...
Good deal 👍
@@wal so what gives...everyone is having all these issues...and I haven't had one..bought the rxd m4 because of your video...k612s are killing it..I'm really interested to find out what others are doing to have the issuea
@@MyBlowncobra I think the k9 is shit but the k6s are good. I cant find anything with k6s smoking or anything. I bought the k6s so i hope im good. How long have u had your k6s and how much rms watts do put to them
@@Silentjustin06 right now I have my k612s on a Memphis mc1000..it makes a touch more than the 1200 the subs are rated for...not a single issue..love when people give props on the system and then get told it's rockville subs...lol
@@MyBlowncobra the k6s are good also do u know about impedance rise yo subs probably seeing 300 watts each or less if u have a 1000 watt amp
The Rockville's will Rock Your World!!
This sub should be rated 250 watts RMS. Rockville way overrates their subs and amps.
Why??? I have 4 of the K9 8's on 2k watts rms giving them all they are rated for and it takes it just fine I can probably throw another 1k on em just fine they shake my whole truck at 70 mph my wipers move off the windshield
@@yamariderAllen post up some videos.
@@yamariderAllen what amp are ypu running?
@@Jackmerius_Tacktheretrix the rxdm3 from Rockville my shit hits harder then a drunk step dad on a Saturday night
@@yamariderAllen doubt its doin 2k...
Awesome collabo! My 2 favorite audio dudes!!!
😬👍
I got a clean non offensive comment.
It would be cool if you and exo would do a colab video on a musical budget db build say 1500.00 or so ,something thatll get loud but play music and sound good on a budget I think 1500.00 is realistic for most folks or achievable anyway,just a thought Lord knows you have the perfect amps and he builds nice enclosures and both have knowledge to the moon 😁
Big D Wiz!!
Old school.
That K9 isn't even broken in yet lol
Dat HCCA 3k broke it in...
I am a new subscriber and really enjoy watching your show. It has been educational. I appreciate you taking all the time to do this for all of us that aren't as experienced in the field of amp's. Thank you
Thanks for the tests. You really spent a lot of time testing and giving accurate info on all 3 sizes! Awesome vid Big D !
Rockville dropped a response video for the K9 Rockville subwoofer in response for your video and EXO video
Watched both your video as well as EXO's. Was cool that the 2 of you did a collaboration on these subs. Really enjoy your work. Keep it up!!!
I really like the look of the subwoofers the magnet and the boot do look very similar to the SA 12. First thought in my head was Drop in a more Stout coil and this thing would do pretty good in a SPL build. Hmm I think that would make for a good video.
First thank you for all you do,we've all learned somthing new in one way or another fom your love of bass and audio. Plus reminding us to just have fun, all while beiing a good teacher. I really mean that , and hope the videos never stop. Thanks Again
Awesome video as usual big D . Been watching and a subscriber for many years . Keep it coming .
Yeah boyeee 👌
Like the man said give em 80% of the rated power and these are sweet for the price!
Great video, thanks for all that you do! Will check out Exo, too.
A new sub might be just the thing to go with the old-school gear I have on the shelf waiting for a nice sunny spring day...
i have the K9 12 in a qbomb spl box. i bought it before seeing these videos. i have only had this sub heat up once. i ran it through a second recommended break in and have not had a problem since. ive been running it for almost 2 years on an old directed 2400.1d. ive been thinking about adding another just for fun but one has been plenty.
Have you considered testing the Dayton Audio's Ultimax Series subs? They seem pretty beef for the price.
Yes, and I will 👌
I would love to see every sub on the market tested like this. Awesome video man keep doing good work and keeping the public informed with real world tests. Also helps to keep these companies in check. Subscribed
My fi 10 was stolen from my car. It was my dream sub too, a super powerful 10 inch sub 1k watts rms. The guy broke in and stole my amp too but not my head unit, because it was a dual brand probably lol. I have a 12 inch enclosure to house that rockville. It would be an awesome replacement because I bought a rockville amp to replace the one that was stolen. I'd be team rockville!
Good luck, maybe you’ll win. Random.org will choose
I've heard very good things about these subs, been trying g to get back into car audio but on a budget. It must be awesome to test amps, subs, and anything car audio. Keep doin what your doin BIG D!!!!
Love the vt big D ,3 kinds of bass from bass outlaws is a great track and I still have cd that I bought in 92 .
I love Spotify 👌
You would be very proud of my brand new loud system. I used an oscilloscope to tune the amp and im not even a little bit scared to turn it up all the way! Thanks to you and your dyno I know the next amp I am going to buy(taramps 3k). I really appreciate your videos and your time thanks again big D. IM OUTTA HEEEYUHHHHH
If you’re going Taramps, consider the MD3000
@@wal Thanks big D!
Damn, pushin to the limit. I would love to get one!
💪😬👍
Thanks for blowing these things up so we don't have to!
Ha ha!
Your videos do show an honest "lab-type" test result of a component's performance below/at/beyond the manufacture's advertised ratings while installed within the manufacturer's requirements.
Aweome videos and a very cool vibe!
Thank you!
Thanks for watching and commenting!
Thanks for posting this, y’all are my two favorite audio youtubers
Thanks for putting in the time, effort, and money to give us this review!
👌😬👍
Nice i hope I win the sub i love watching you and hifi vegas amp dynos
I have been slamming my 12" K6 on a audiopipe 1300 in 1 ohm for over 3 year's in a sealed inclosure! Not one issue. I beat it up!
This was very interesting , and the way you explain everything , showing us stuff which we are sometimes afraid to try , is really nice. Thanks for all your efford to make this videos.
As always Big D great stuff!
