Amps and subs installed.....doesn\'t thump like it should! Heres the skinny, I just installed a new stereo(JVC), Amp(Kenwood 300 watts 2 channel),2 subs(Rockford fosgate Punch 2's). The stereo has a line output just for the subs and rca jacks for front and rear amps. Through the sub amp I have the Kenwood 300 watt and in the rear rca jack I have Punch 100 watt pushing 2 6x9's. For the sub outlet on the stereo there is only one left and right rca connection. So on the amp I have one left + and right -. Basically running one left and the other on the right. Both speaker outputs on the amp are used and running to the Q logic box. The thing is, it doesn't thump very hard? If I bridge it i can only run one speaker or tie both together and bridge it. That would just split the power back though.....I think??? Any advice would be great!
