I'm installing a PA on my car in front of the radiator and behind the front fender. The speaker wire is going to connect through the firewall into the cabin where the CB radio with PA option will be housed. Can someone help me with finding holes in the firewall without tampering too much, and where to find them in the cabin and on the engine side. I have a 2004 xterra se. Thanks!!
