awsome power and sound
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.

Money!
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.

Best four channel in the segment
Jbl gto amplifiers are the top line of Jbl amplifiers, yet the model here that is gto 504 is truly a amazing amplifier in it's segment can do a lot for the money pain can be used as 4/3 channels but some use it as 2- channel driving the subwoofers
