5 Star Rating mtx audio From GA

I have the 600xd amp pushing two jackhammer 12''s overall it has really great sound quality and crazy bass. my little S10 beats out the rest of the competition.

5 Star Rating DaBudman From Everywhere
I have this with a 10 inch MTX in a sealed box and it hits hard in my truck. I need a highs amp to keep up. It can handle the heat in Sacramento and New Orleans. Great amp.
5 Star Rating DeShawn Alston From Raleigh N.C.
I had a custom box built for my 04 impala with 15 inch subs, and i needed a test amp to make sure the subs worked.The place only had the MTX amp open box so i hooked it up and the sound from the amp was shocking, i paid for the amp on the spot. The amp preformed great, didnt get hot and pounds with every beat.I hang with some of the big doggs with mad money in there systems,im getting a bigger amp but this MTX will not let you down.
