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.

Have you guys hooked up the remote turn on wire from your headunit to your amp. Since your amp is wired directly ot the battery it's got to be "told" when to come on either automaticly when the head unit comes on or manually with a switch between the acc connection in your fuse box and the amps remote terminal connection. This is so that the amp won't drain your battery when the car is off. Without power to the remote terminal on the amp it thinks the car is off and the amp won't turn on.
