Wiring an amp and a sub, Installation Help Please Options

[powerkor]

Hello, Im trying to install an amp and a sub (both from the trunk) of my 97 ST celica.

My understanding is that I power the amp by wiring directly onto the red battery terminal, but my question is where in the firewall is there the most accessible hole to run the wire through? Let me know if I should do it this way, or just try to hook it up to my fuse box instead.

My second question: to bridge 2 channels together, I'm using the + channel from the one and the - channel from the other, I think this is how you bridge, but im not too sure, this is my first attempt.

I plan on doing this later today, so the quicker the feedback the more happier you guys would make me :-)

Thanks for your time.

If you have an aftermarket deck you should have a wire specifically for that...should say "Remote Turn on" or "Remote Lead". Then hook it up to the "REM" wire or terminal on the amp.
