So it is best to just replace the stock amp with aftermarket amp. Do I need to look for an amp that has a 2 ohm output? What about the speakers in the front. Do they have amps on them or can I wire them directly to the Z1? Which wire harness is preferred? I hear the VW wire harness is what most installers are using. When I pull out the oem stock unit, connect the vw harness to the existing harness in back of the unit. Then I take the wire ends of the vw harness and connect to the Z1 such as power, ground, remote. Am I understanding this correct?
