Hi, I am in the middle of installing a new sound system to the car, and I put in component speakers to one of the front doors of my 3 door MK4 hatch today.
For the input to the component crossover I used the OE tweeter and woofer wiring. Can you do this or do you need to run your own wires in all the way from the head unit?
The speakers will be amped up soon, but if I can just use the OE wiring, I will connect the feed from the amplifier into the wiring in the passenger footwell. This means if the door needs to be remover for any reason I can just unclip the OE wiring block on the door, as the speakers will use the OE wiring through the door connection.
