My review I did:
I purchased this amplifier to swap with a Rockford Fosgate "T" series amplifier. Night and day difference. The Amplifier produces a very crisp clean signal. Clamped number per channel are as follows for my setup:
Ch.1 and 2 - 84w @ 3.6ohm - Midbass drivers
Ch. 3 and 4 - 82w @ 3.8ohm - Tweeters
So therefore the amplifier is slightly under rated. Using the on board crossover features the amplifier is running four midbass drivers and 4 tweeters. Very detailed midbass from 50hz and up unlike the rockford which lacked anything and had distortion below 120hz. With small amounts of amperage draw at high volumes this amplifier is a great factory add on. It looks very sleek as well.
My only con would be it has close to no heat sync fins to help with cooling. With that said mount this amplifier with ample airflow!
