    • Very Happy Customer
I purchased this amp awhile ago. I have it hooked up to 4 MTX 12 inch terminators and let me tell you, this little monster is a game changer. Dyno tests proove that this little amp shoves significantly more power than what it claims. Absolutely pounds the snot out of my subs, highly highly recommend this amp to anyone looking for compact power. 5 Stars from me. ... show more

    • BUY ITTTT
amazon has a note saying most returned. i don't see why it would be tagged as that. great output, underrated by at least 15%. definitely hitting 1800-2000 with out a doubt!! Bass control and sound quality was a big concern of mine and this would land in my top 5.

    • Puts out alot of power
No false advertisement with the power sundown amps produce, it's actually underrated it almost does the top rated power at 2ohms as it's advertised for 1ohm, I'm pushing a sundown x8 d4 wired to 2ohms and it pounds it to the Maxx, the amp is barely up, I'm going to have to hook up a second one, now I know it will power them both ... show more

    • Refund mistaje
I need to edit my 1st review. And there was an issue with the amp, when it was connected it said it was in protection mode, I notified the company and they let me know to do a replacement. I was notified that a new amp was coming, as soon as I sent the other one back I got an email saying that the replacement was canceled. Now I’ve had my backseat out of the vehicle waiting on this amp just to get an email to weeks later saying it’s no longer on its way. What a waste of time ... show more

    • Small amp. Big punch. Just call it Manny Pacquiao
This little amp really delivers the Big Bang. I’m so Impressed. I have it paired with two shallow mouth Sundown 12’s in my F150. It definitely gives you the thump you need

    • EST amp I’ve ever owned. Pure power in small package
Hands down best amp I have ever owned. Extremely powerful and pushes my ddx10 to the MAX!!! Clamped 500 watts out of this amp with gain barely turned. Rising to 3.5 ohms. Set gain with a DD1 and I gained 5db. Have yet to clamp it since then. This is a great amp. Highly recommended. I switched from Korean to this and I’m way happier with my setup!!$ ... show more
