I currently have a Pioneer D3 headunit which I love but I think its time I upgrade the rest of the set up. My roommate got me two sets of 6x8 (I think or 5x7's) sonys from Circuitcity for a really good price when they closed everything out. I also got a really nice (I think MTX) 4 channel amp from them as well. I was going to put all this in my mustang but I sold it around christmas. So my first question is where should I mount the amp? My truck is a 2000 F150 regular cab, I was thinking of straight behind my seat on the back cab wall. Second question is for wiring, should I just run all new wiring to save me a headache of trying to find out what goes to what speaker?
