I have two 05 Kicker CRV12. I have 1200 watt's running to them (600 each). I like the bass but I think it is way to much for my trunk (97 Nissan Altima). I want to have the thump so my subs slap with a good clean bass. What level should I have my Highs,Lows,and Mids at!? I'm new to car stereo but would like some help!
