Hey, I am renting A 2004 Mazda 3 hatch for a road trip. To make it a little cooler, were removing the intake silencer and putting an amp and subs in it. The plan is to run a fused hot with a switch to the amp, and then ground it however we can, using the speaker leads for input since the amp can hook up that way, but we dont know what to do about the blue remote activation wire. What do we have to do to make this all work? What else will we need to consider? will this WORK? we think it will, and it'll be so worth it.
