yes you can. the plugs he is talking about clip into the factory speaker harness in the door and have 2 wires on the other end. pretty much there usually $10-$20 and are not needed.
ok what do think i should hook the wires that came with the speakers to the factort harness then to the speakers because they have the little clips or can i just go straight from the factory harness to the speaker?
so far: borla catback exhaust, audio swap.
waiting for warmer temps
