Amp installation & Firewall

Hey... just wanted to know what the easiest way is to get my amp connected to +B is.  I have a 1993 Mitsubishi Diamante and I'm trying to look for a place to run the amp cable through to the battery, but I can't really find one.  Will I have to knock out my own hole or something somewhere?  Is there a more "graceful" (or existing) way to do this?  Thanks!

Also, my car has a power antenna, but this deck I bought only has a "remote out" output that has +12V when the stereo is on, and GND when off.  I was going to tie that directly to my amp to turn it on and off accordingly, but can I also tie it to my power antenna to make it go up and down?  Thanks.

Make sure ya take out all of the insulation on the inside of the firwall so you can make sure you not drilling any wires

And GO SLOW with the drill bit.....stuff on the engine side of the firewall. Drill a small hole and check for problems....then make the hole bigger if all is well.

You mite want to wire a relay for your turn on and antenna wire, it might not suppl enough current to do both.
