i am about to rewire my rear speakers becuae something is messed up somewhere along the way and i only get fuz in one of them. How much wattage does the factory amp put out? If it doesnt put out as much as my aftermarket reciever (22watts RMS/50 max x 4), im just going to bypass it.
I'd say rewire. Its going to sound better no matter what b/c your factory amp does not have any inputs on it and you would have to use a line converter, which never really works out.
just my 2c
