i have a 4 guage power wire run for my 600 watt concept amp and i have been trying to find the best place to get through the firewall. The amp is pushing two american pro 12" in a custom built box. for mids and highs i have a memphis coponent system. 6"1/2s in the door and i am looking for a place to mount the tweeters. Sony headunit. If anyone has any tips on the firewall or the tweeters please let me know.
