connect amp to factory radio

i need some help with my factory radio. I got a 1994 toyota 4runner, with the cd/tape radio.  Im looking to connect my amp, (remote wire, and a high-to-low converter) to the radio.  theres mainly one plugin the back of the radio, with about 16 small wires coming from it. I wonder if there is a key for which one is which. theres two black wires in the corner but im sure thats the antenna and ground.  Just looking for the remote wire, and two for the speaker connections. please help and thanks alot if you do.

You may just have to test each wire to figure out which wire is which. It shouldn't be that hard. Just get a tone generator, a meter and go to work.

Don't let the smoke out of your equiptment..it doesn't go back in.

There is NO remote wire on the back of a factory deck.  Use a switched 12 V power source for remote, or use a signal sensor unit (look at Peripheral) to pick up an ON signal through the factory speaker wires.  Easiest is to just wire into the dash onto a 12V switched wire and let the amp come on with the car.  Hook the LOC leads to speaker wires at the speaker locations and you won't have to figure out what wires are what at the back of the deck.

Use regular 16 to 20 gauge speaker wire (or Bell wire) to connect the LOC to the factory wiring.  Twist the wires around each other rather tightly (+ and -) and run them back to the LOC location near the new amp, then run RCA's to the amp.

If it would be easiest for you to hook up the LOC leads to the wiring at the back of the factory deck instead of at the actual speaker locations, you can find the + and - wires of the front pair of speakers by using a simple 1.5 volt D battery, slicing a nick into the OEM speaker wires, connecting combinations of wires to the + and - ends of the battery until you hear a sound come from one of the speakers.  That will indicate you have found the wires to that speaker.  When you have located a pair (four wires), tape all the other wires up where you have nicked them.  Then make sure the polarity is the same with the pair of speakers you have located (the connection to the D battery will cause them both to excurt outwards instead of inwards).  And note:  any small battery will do the trick.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

I use the PAC trunk loc.  It has a remote turn on already.  Also a small line driver built in.  You wont even need to remove your deck or find any wires behind the dash.  I have had very good luck with this product, so easy!!!

to wrcpeugeot, in all honesty, I do not recommend any high-low level adaptors, although some work better than others. They all tend to introduce noise/hash and intermod noise to your aftermarket amp. Save up your money as run as fast as you can to a car stereo store and replace your factory radio. Even a 99.00 JVC CD PLAYER with amp jacks will sound better/cleaner than your factory radio ever will......

GOOD LUCK.....
