Not if I reuse the factor wires. I don't plan on running too much power to them anyways. So I figured the factor wiring would be sufficient.
I might attempt to put them in the kick panel and reuse the factor wiring going to the doors for the woofer and run a new wire to the tweeter from behind the dash.
Ideally I would prefer to put it behind the door panel though. I might just take it to someone to have them deal with the headache of running the wires.
