ummm no..... I was saying adding an aftermarket head unit not the speakers. If you add the aftermarket hu then your factory amps will no longer be of any use. because the factory hu uses no amplified signal processing. Then basicly sends signal to the amps to be processed and sent to the factory speakers. If you add an aftermarket hu then you will no longer be able to use the factory amps. now replacing the stock speakers with AM speakers then yes you may have to run a little wire or you can look for wiring adapters but still...
