ford radio question i know it doesnt belong here

[wruth]

i dont really post here much, i mostly just read the good threads, but i am trying to install a sub in my gf's 2001 ford focus with a stock head unit, and i ran into some wiring problems. 1. i need to install the rca adapter, but i dont know which wires are for the left and right speakers. 2. i need to install the remote amp turn on wire which i dont know where it would go. i was wondering if anyone could help me out with this or provide a wiring diagram. its the stock cd player for a ford focus. i cant stand that she drives a ford btw.

I don't know much about fords man. I wish I could help you, www.the12volt.com (http://www.the12volt.com/) has wiring diagrams etc. you can purchase for cheap.

My advice is this:

No matter what the car, buy a cheap $100 aftermarket deck rather than install one of those noisy RCA adapters. The adapters are really more trouble then they're worth and sound horrible as well. If you purchase an entry level deck, you can buy a wiring harness to plug into your stock harness and *bam* you'll be able to hookup your amp.

If you're determined to use the stock deck and haven't cut the wiring harness (hopefully you haven't) you should be able to pull out the speakers to track down what color(s) of wire there are attached to the back of them.

If you have already cut the harness, you can use a 12 volt (no larger!) drill battery to test your leads. Make sure that the leads you test are not power, ground or dimmer, the following test could really fry your electrical system. Use a multi-meter to test the wires to make sure they're not live both with the car off and on. You can also test for the power antenna (remote on) lead this way as well. If your car doesn't have a power antenna, anthing that has 12V of power with the key on will suffice. Make sure if you're going this route, the lead doesn't have power when the car is off, or your amp will stay on and kill your battery.

Once you've determined that the leads have no power with the car off or on, you can take a pair of the wires and touch the 12 volt (or less) battery to the speaker leads, one wire per terminal. When you get the right pair (one positive and one negative on one speaker) this will cause the speaker to emit a popping sound similar to a bass response note. If this is done with a battery less than 12 volts, it will not cause you speakers harm. Anything over 12 volts and you risk frying your components/speakers.

After you've found a pair of wires, a good way to check and make sure which is positive and which is negative is to pay attention to which way the speaker moves. If it moves outwards, you've got the positive wire on the positive battery terminal. If it moves inwards, you've got the negative wire on the positive battery terminal.

I hope this helps, If you need further help on anthing, don't be afraid to ask.
