Wiring Up a Power Amp and Sub Woofer, pre existing hot wires? Options

[Lexicon_Devil]

I'm in the process of taking my small, alpine power amp and sub box
and wiring it up to my Celica. My stock amp is already bypassed and
the car is pushing the six speakers from the head unit.

I'll be using the RCA outs of my head unit for the inputs on the amp.

My question is -

Are there any wires down there that are already "hot n ready" for the
amp? Or will I need to run new wiring? I need power and a ground.
I don't want to cut into my head unit. Want the amp and woofer to be
independent.

Thanks guys.

By the way, I already have the console tore apart. I'm just lookin' for
a possible tip. Haven't played with it since I installed the head unit in
2003.

Finished it. Sounds great.

I ran straight from the battery, through the fender, through the driver's door
and to the amp. grounded underneath the hatch latch and hooked up to the
power antenna.

It's just a small amp and small sub. Just enough to give me the low end I
lose from driving / road noise. Totally does the job.

Thanks for all the help.

Noo! bad idea! lol if u run it in the fender though the door jam the wire will break over time or short out. u need to run it though your fire wall drill a hole down and a little to the left of your clutch you have a 4 inch opening were you can rout some wire or take your fender off and run it with the rest of the factory wires are ran and then pop it in the back side of the kick panel. trust me the door is a very bad idea....
