Help, i need to find a wire
well my brother and i are trying to do the sub and amp install on my car using the stock head unit.
The only problem is i can't find the power on wire for the amp.
If anyone knows which wire it is PLEASE reply as i need to get this finished up b/c i need to drop my car off to get inspected
thanks
Matt

Generally you turn on an amp form either a power ant lead or a remote turn on lead. Neither of which ar on a factory headunit.
So your solution would be to just hook it up to an ignition wire. Find a wire that goes hot when you turn on the car.
Or the other solution would be to pick up a line output convertor that turns normal speaker outputs to line level outputs. Some of these have remote leads on them for amps.
Or lastly, better amps can actually sense an input when using their speaker level inputs and will turn on by itself.

hey thanks for the reply
yeah i was looking at those line level changer thingies except my amp pushes 1000 watts and those things say they are only good for like 50 amps max i would burn that up in a second!
soooo hmmmmm
but shoudln't there but a radio turn on wire b/c the radio needs to sense when to turn on and off when you turn the key in the ignition right???
But thanks for the help so far, im getting to the point where i am going to go out and buy a new head unit

ok hey i found out that my amp is suppose to turn on if it has speaker inputs
so now i thought i had it hooked up to speaker imputs but i guess i am wrong b/c it still won't turn on, the speaker inputs on the back of the radio are the black ones with red dots correct???
Any diagrams would rock
Thanks

be sure and check your ground on the amp; as well as the hot line (with a multimeter). If either are messed up obviously it wont turn on.

Hey guys,
Thanks for all the help i believe it was a bad ground, i got it ghetto style on one of the bolts on the roof of the trunk, ill have to tap a screw into one of the holes but thanks a lot for guiding me through the way.

Let me know if it works for you it works perfect in MY01 RS so it should work good in your car it took me a while to find it after checking every wire going into the stock deck.
