One of the thing I want to test is actual amperage draw 1ohm vs 4ohm. 2X M2500's weren't pulling 500amps @4ohm and I bet that RF1500BDCP was under rated and pulling more than 200amps I try to explain this to people all the time I don't know how, I'm going to try right here; I'll use DD amps as an example, all things equal, If you compare a DD M2500 @1ohm to a DD M5000 @ 4ohm and set the gains so the output the same power (1,700wrms for example) it is safe to say the M5000 will be drawing 1/2 the amperage, have 2x the damping factor, almost 2x the dynamic range and run significantly cooler than the m2500. BUT the consumers don't want all that they want Watts per Dollar I am I big proponent of overhead and having more than you need BUT I'd also do a larger single amp in the same series, 1X M5000 is $600 less than 2X M2500's (MSRP) I always tell people to "run the highest ohm load possible to get the watts you need" just my opinion.......
MB, appreciate the video. I've run many amp setups and as far as visceral sound, I much prefer to run 1 amp at 90-95% capacity than multiple amps running on a light load. Alot of these amps don't start to shine until 75%. I have 4 Gately Relentless 8s in my Raptor. I originally was using an Incriminator Audio 6.1, but now using the 4.1 at .5 ohm and the is much more violent!!!
I remember I commented back in the day that your sundown x8 v3 needed more watts than the RF1500bdcp and you said it was about efficiency. fast forward a few years later MB said he running 2 DD 2500 on 2 8 inch subs. I was just scratching my head because it contradicted your previous statement, but I'm glad your moving back to efficiency again. keep up the good work on the videos and God bless you.
feel like some of these brands are just selling you power you can even see in the pictures they dont even show the sub from the front then show you that big ass magnet in the back
Before assuming how much power it's drawing, I'd put a clamp meter on it and find out for sure. I would wager your efficiency was better with the pair of M2500. Typically, efficiency of the amp drops as you decrease the ohm load. So 4 ohm is usually more efficiency than 1 ohm. A big amp running higher ohm loads can run easier and cooler than a smaller amp running a low ohm load. Anyway, the clamp meter will tell you the actual numbers. 👍
@@M.B.EnclosuresSure it does. I run a 4k system on a stock electrical system. It works fine because I'm only using an actual 800w to 1,000w at most. I have lots of headroom. Efficiency is great. Amps always run cool and never get stressed. It's not efficient as far as cost, but I can afford it. Lol.
He will probably tell you that it is a cookie cutter because the Memphis mojo has the same design as several other subwoofers on the market, same basket, etc. not a bad woofer, but not the greatest thing on the market either. They give decent performance, but nothing proprietorial about them
Iol now you thinking like me.. im running my 9518sc on a prime 1200.. the same amp you test your 8s on. The key is that amp is 80 percent efficient.. i have amps in my collection that do well over 3k.. but its far more impressive knowing im floating stuff with a entry level 1200 amp.. 😂
@@LeonD519 lol 🤣 .. honestly not moving it that much.. but you would be surprised at the output.. I feel sorry for anyone pulling beside it with the wrong setup.. I know that
I appreciate the authenticity and willingness to look at yourself. You and your wife are a tremendous inspiration!
Bro! I started watching this channel a week ago! Got me some 8s for the 150!! Done got me hype!
Introspection is so vital to growth. I'm glad you made this video and shared it with us.. Keep pushing sir. We appreciate you.
I finally/ truly understand this video!!💯

Now that’s how a man admits his mistakes 💪🏾💪🏾love yah big dog
Thank you for keeping it 100. I’ve learned so much from you. You make this hobby fun and exciting.
You doing a great job my friend. Thank you for the info.
Much appreciated
MBE love your honesty .
Yup ,people love to hate you when they not you, but somehow still keep watching you...even if from a distnace 😮😅

Back to bassics. Music is a blessing. Can’t wait to see what you do next, MB.

Yes, exactly
Do something with a pair of sensitive, lower power handling, DD subs and see how loud you can make them!
mbe you are absolutely right !!
looks clean my brother!
I agree. I have one JL HD1200 on two B2 rampage 8's and it sound GREAT on stock alternator and battery.
I have the new revision in stock
And can make any subwoofer sound good ❤
I have two dd2508D on on JL XD1000/1 v2 it pushes them just fine. My explorer still shakes when I push them hard enough.

@@lowridr2 fact
My installment is a landmine but my system play sweet like honey. I need to do a better job on that though fa real. 😂
I need a box for 4 x8v4 for my f150 crewcab, I already have a 2.5" seat lift, might need a box for 4 dd 2508 sc for same truck
Let the box do the work
Install looks pretty good to me
It's all about Chevy Duramax power 😆
Salute bro🎉

That doesn’t justify running 5k to power :2 8’s

The info channel 🫶🏾
I got them new kicker solo x 10s coming under seat box watch out now!!!! MBM
Do u make any single cab enclosures for the 21 and up F-150?
I can.. my boxes are custom.
Top Dog!!
Hey my guy question? I have a suv will the speakers sounds better facing up or facing back
I know the thd on the m4000 and m2000 is .2, is it the same on the m2500? On their website it's not listed. Thanks in advance.
So What you looking to sell those used m2000 or m2500 amps for?
They sold already.. sorry
I can get a used 13.5 w7 for 500 in a ported box, should i go for it???
Yep
@@tarriouscarr2503 👀 bet, thanks for the quick response m8
Hey bro, what is your opinion of Memphis mojo and amps

You know me well..😀
@@Chuck_SandersI seen that also.. but for 650$ they can keep it imop..

Poor sub, not even getting anywhere close to what it should handle. But to each their own I guess.

@@MatthewGuynn-ki8rn yes sir they are nice subs
@@LeonD519 probably doin close to a 150 on just the 1200.1. stock electric ⚡🫡
How many ohms?
Wasnt youre original thought about it was to be able to run the same power but at 4 ohms for better control/sound quality?
Yes but it’s sending the wrong message
Yes they do especially after they lose a little unnecessary weight wink wink 😉 lol
