I wanna amp my stock escort speakers. It is the premium system that already has an amp on it now, but I would like to have a clean 50x2 running to my back deck speakers and use the stock 25x2 amp for the fronts. The setup it has now, is stock deck (5x2rms or so on fronts) and 25x2 rms on rear. I wanna run the wires from the stock amp to my door speaks, and put a nice 50x2 on my rear deck. Does this sound like a lot of trouble for what im wanting to achieve. ?
