Let customers speak for us
from 3554 reviewsTo be honest it was bigger than I expected and hit a lot better than I thought all though it don’t hit all the lows the sub is amazing for one it matched my 2 sundown 12 just with one I will be sticking with this brand

so I had these installed in my front door, straight to my aftermarket Kenwood, and these things scream, very impressed, my buddy will add a 4 channel amp, and I will update after that

Marine and Powersports Headunit 3" Color TFT screen , 2 Zones, 4 volts Output, BT, RDS 4 X 50 Watts

I absolutely love how it looks in my JL

The amp itself was great and a great price but was too large to fit in my motorcycle firing so I had to return for an exchange for smaller amp, I was charged $70 restock fee on top of having to pay an extra $85 for the exchange only having the amp for 1 day and no use 🤬 Rule of thumb, make sure of the size you buy before you order or you’ll end up paying more it you have to send it back..!😖

Very nice.. would love to add your product to my car audio shop.

For 4 speakers I used two of these amps and am verp pleased with their performance. I'm getting plenty of power but on my Harley at highlway speeds, I fairing speakers just aren't big enough, so it's time ot speaker shop!

As advertised loud an clear!

Easy to install and sounds a lot better than stock

Voy a comprar solamente su producto y mi sonido será de ds18

Installed the 10inch enclosure in my 2022 GMC Acadia. Sounds great,the bass was just what I wanted. Just enough to improve the sound inside with the limited space i had.

I put 6 of these in my Honda pilot and the fucker took me to mars while bumpin Tupac wtf do I do now

Love this amp paired with 1 exl-xx12.2dhe
