Good for the price

This amplifier is really great for running a good pair of 6x9 100w rms and a pair of front speaker 50w rms. I tried to bridge 2 channels and run my 10 inches sony Xplod but it looks that there is missing a little bit of power to make it sound clean. I suggest you to use this only to run 4 speakers because running a subwoofer is making this amplifier overheating. Overall it sounds clean and it's probably the best 4x100w rms amplifier on the market for the price.

Love this amp

This amp has been with me for a long time. My first sub was a 12" Rockford Fosgate P2 (the older model). Bridged at 2 Channels at 222 watts, the sub hit hard and rattled things in my truck that I didn't know existed. Now I'm the happy owner of a 12" Kicker and this amp is still enough to satisfy its thirst for power. Soon I'm going to double up on the Kickers and I'm fully confident that this amp will be able to power them both when bridged.

INCREDIBLY CLEAN

While not the smokinest amp for cosmetics, it is extremely clean and underrated. I am running to the Infinity 6.7 components (2 OHM) and they sound great. I am Running a panasonic deck with 5 volt preouts so the gain is set pretty low.
