I am hooking up a subwoofer in my 01' civic and i cant figure out where the remote wire from the amp connects to in the back of my new headunit. Do i need a wiring harness? any help would be appreciated thanks
Assuming that you're talking about an after-market head unit, the remote output should be blue/white. If there's no blue/white, look for a blue wire, but if you see both wires then use the blue/white. The solid blue wire is typically a power antenna output, and won't keep your amp turned on when you select the CD player or another source. If you have a stock radio, then I'd suggest connecting your remote wire to the power wire at your cigarette lighter, below the radio. That's typically a key-switched wire in a Civic.
The remote wire is almost always the blue one. If it is an aftermarket deck that has never had a amp installed, the remote wire shouldn't be connected to anything and should always be blue. If your using a stock headunit it may not even have one, the best thing u can do is connect the remote from your amp to something that will only work after the ignition is turned on, if your not sure wat wire is doing what, to test them simply join both power wires from your deck together (the red and yellow wires), and connect the ground wire (black) to any metal earthed to ur cars body, just touch the joined power wires from your deck to any wires close by with ur ignition turned on until you get power to your headunit, then turn the ignition off if ya lose power to the deck then u can just connect the remote from your amp to that. While checking the wires the worst that can happen is a blown fuse, so just have a spare 10amp fuse or two just in case. I hope that helped ya out. gl.
It'll more than likely be a blue wire with a white stripe coming off the back of the aftermarket deck.
Connected it to a (+) which only on when you turn the key to ACC. Good luck.
