Ignition wiring

Just about to hook up an amp. Wheres the best place to get the power from? I want to hook it up to the ignition so its only got power when my ignition is on. On my old amp i wired it straight to the battery (not good leaving it on can drain a battery fairly quickly) so wiring it into the ignition would be much better. I dont really know how to do it, i could muck around and id get it eventually but if anyone can give some help it would save time.

its usually done from the battery for a good connection (with a fuse right next to the battery) and the stock wiring probably wouldn't handle it. The wires arn't the thickest so..

I'd still wire it from the battery with 4ga. or something.

I didn't know the amp drained the battery when its not getting a signal or what not?

time to let the guru's step in

The amp often has an extra power wire connected to the back of the radio, this is the signal. If the radio is not on, the amp draws no power.
All the same, I tested mine when I installed it...

you usually connect a wire to the battery for constant power then another wire which is remote turn on which goes to the back of the head unit which makes it so the amp only turns on when the head unit turns on.

You would be mad not to connect your amp to your battery. Make sure you have a fuse installed near the battery too.

Use proper power cable. Its the red stuff (my brain cant seem to recall the guage of it...someone will know) and make sure you run ALL power cables down one side of the car, and all speaker cable down the other.

yeah as the others have said
1. you need a good power supply for the AMP ( has to be nice thick wire fromt the battery )
2. there is a wire that hooks up to the head unit so that the amp turns on and off with the head unit
