doing an install on this car coming up it already has an after market hu installed.we will be replacing the speakers with new component polks adding 4 chn and a mono amp. the person i am helping wants to spice into the wiring harness to run the components instead of running the wires from each speaker to the amp. dont know why but his car im just helping. if you run the speaker wire from the speakers to the 4 channel amp does this in a sense by pass the factory installed amp or does that still need to be bypassed?also if it needs to be bypassed how do you do that. thanks for the help
