Decent

Bought for friend when he started having issues with RE Audio amp. Put in his new car and powering CDT comp. in front & CDT coaxials in rear. Install was easy & set up was a breeze. His speakers are rated at 100w & 90w respectfully. This amp drives these speakers with no problem, no distortion & does not get warm. Good little amp & I recommend with no reservation.

Good little amp

Got this for friend and helped him install in Infinity. Was very easy to install and all the features were straight ahead. He is powering CDT components & coaxials in rear. Plenty of power, no distortion & does not get hot.
