Great product for the price

I was looking for a good amp without blowing the budget. I paired this with a Kicker CompRT in my F-150 and it works fantastic.

Good Amp, Great Price!

I am always impressed with MB Quart Amps. I own 4 of them now and 2 of them are this amp. They get a bit hot but definitely do the job.

Total Steal!

I purchased this amp after getting two different cerwin vega amps that were junk. Overall extremely happy with this product and the price I got ($100). That's why I think it's a total steal- previously I had a 250 watt Memphis pushin two skar 8s and now that I hooked this MB I have double the bass and it hits clean and hard notes. Everyone compliments the crispness of the bass and it is just loud pushin those 8s now. Definitely recommend! Easy to hook up and lights up cool. My only concern is it does get warm the few times I've checked it so I'm gonna keep an eye on that. Just a heads up. Totally willing to buy more MB Quart products.

GREAT VALUE!!

For the price you can't beat it,have this on a dual 4ohm sub wire to 2 ohms and doesn't even get warm.

Wow

one of the best amplifiers I've ever bought. I would definitely recommend this to anyone who wants to add bass to their system. You definitely cannot go wrong with this amplifier.

preformace

I have this amp hooked up too a Polk MM-15 in a air tight sealed box in a reg cab pick-up so it's pushing the sub with over 120rms over the rated 380rms of the sub and when the sub is broken in more I would think it would handle a whole lot more from this amp. Further more I have bass at all levels of listening wither it's at low vol or when I just want to crank it up to hear it hit damn hard. The only thing that I can say is it's down side is it's foot print but hell small cab.

Nice Amp

I am running this amp to a single 10" Kenwood sub in a ported box, and it pushes it great. Amazing amp for the money!

Excellent amp to put under the passenger seat!!

I used this amp paired with a JBL GTO804 8"sub in a custom enclosure and also for a 10" w3 in a stealthbox it works great with no issues for either one. The bass knob is perfect to change bass for different songs on the fly.
