Got this from sonic eletronix and hooked it up and wow. with jbl speakers this thing screams out the sound with really no gain needed. puts out its power if not more. This amp uses 4 gauge, not 8 gauge.

There's not that much to the review of a 4 channel amp. Either its good or its bad. This amp is good! Way good! The clarity of my music is amazing! it is definitely putting out the rated power, if not more. I love the bare wire inputs for all the wiring, makes install simple and secure! I wish there weren't any lights on the front of the chassis, but most people have amps hidden anyways so its not a big deal.

Customer Testimonial

I had a call earlier today, about some different options I had for a
sub and amp set-up. Jeff took the call and was real nice to
work with. We ended up finding out that a sub I ordered was on
backorder, we switched it out with a different sub and he even offered me a discount. It was a pleasure.
