Im running 2 10 inch kicker compvrs off of an auro rpm2300 with 150 wrmsx2 at 4 ohms. the speakers can handle 300 rms a peice. I have my amp at 3/4 gain and bass boost half way. Will it make my amp last longer by keeping 3/4 gain and half bass boost. I want to turn it up but also would like to keep the amp in good shape. Thanks. One more question not about amps. Where can I get cheap kicker grilles for my 10 inch cvrs? thanks
