Kicker Simplicity

This amp was easy to install in a small space, setup was easy using supplied directions. added this amp to boost the subwoofer on my Porsche BOSE system. I have used the Porsche subwoofer enclosure upgraded with a Audiofrog 8 inch driver and a 500 w Kicker Key amp. Big improvement over stock.
