So i have my speakers running off of the hu as of right now and was wondering if i should run my fosgate p3002 to the two front speakers and leave the back two on hu power. keep in mind this is in a ranger which the back two dont do much. should i do it?? also if i do, should i just hook up an 8awg run off of my back battery to the amp with it fused??? im thinking thats a yes but let me know on any input!!! thanks
