Please Help everyone but understand that I am new to the whole stereo install area.

I own a 2007 coupe and the factory amp finally went out. I am replacing it in the stock location as I was able to find an aftermarket amp (JL Audio HD 600/4) that fits into the same place where the original amp is located. I previously replaced all of the speakers in my car and so I am not using any of the factory speakers.

My question is this---In installing my new amp I need to run a power wire and ground wire from my battery to the amp (same location as original AMP). For the life of me I cannot find a place to run the new wires from the inside cabinet (passenger side) to the engine bay where the battery is. Can someone hop me find a hole or break in the firewall where I can pass the wires thru.

ANother thing. The reason why I am running a new power and ground wire to the aftermarket amp is because I cannot find the power wire for the stock factory amp. Also my aftermarket amp calls for a 4 to 8 gauge power wire. I do not know what gauge the factory power wire is. But Like I said I cannot find the power or ground wires that plugged into the factory amp, although I was able to locate all of the wires going to the speakers.

Remember I am new to the install game and so if someone could provide me guidance here I would greatly appreciate it
