How would be the best way to do things. Currently my head unit is controlling 4 sony explode 6x9's (1 in each door of the burb). I installed a 4ch amp and 2 subwoofers also now. Would it be better to just leave the 6x9's connected to the head unit and the subs on the amp or run everything thru the amp? Amp = Volfenhag ZX-7160 6x9's = XS-V6933 Subs = Pyramid PNW10590 10" And I don't want to hear about getting new stuff, cause I'm using this stuff until I can afford something better.
