so im having a bit of trouble putting my deck in my car. the previous owner cut the wiring harness, and installed new speaker wire, but left the old wire as well...so i have alot of wires, and dont know what most of them are for. theres all the stock wires, plus 5 yellow ones, which are for the speakers(not sure why there are 5, and only 2 of them seem to have ever been used out of the 5). the car is a 92 eagle talon, and the deck is some cheapo canadian tire nextar 990c or something. i understand all the mathematics of car audio, i just dont have much actual hands on experience and i dont wanna fry anything...if noone can help me thats fine, i guess ill just use a voltmeter to find out which is which, but i will be hard to do so because the wires were cut a bit short and arent too easy to access.
