Car Audio: Power wire from battery to inside vehicle. HELP!

[96Mazdamx3]

Hi I'm new to the forums as I am new to owning a mazda. I just bought a 1996 Mazda MX-3 for my sisters grad present. Just went and bought her $1200 worth of kenwood car audio (with another 5-$800 on the way) and need help getting power inside the car from the battery (Semi-professionally fits this case best). I only have another day or two to get this done and any immediate help would be GREATLY appreciated. If you feel comfortable shooting me a text you can text my cell at 1-867-334-5627 or respond here. I will be back and fourth from the car to the computer figuring things out.

Thank you for your time and I look forward to hearing from somebody shortly!! :]

If you're going directly from the battery, on the driverside firewall, under the hood, there is a black rubber grommett, approximately 2 inches round...just pry that out with a flat tip screwdriver, drill a hole in it, or cut an X in it, run your wire through it, and re-insert the grommet back into the hole on the firewall. the hold exits on the interior driver side, under the dash, above the pedal assemblies...pretty straight forward,..
