i got mine done by traffic jams in buford,ga. They ran the line from the battery under my dash (around the steering column), then from there under the trim along the door to my amp which is on the back of my seat. I had them leave extra wiring just-in-case which i put under my rear seats.
I ran mine from the battery, through the firewall (I had to drill my own hole/add a gromet), down the left side of the car and through a hole that was near the top of my left rear passenger seat. It leads right into the trunk without having to travel around the seats etc.
Nice, I have two JL Audio 12w03v3's and at the moment I need to buy a more powerful amp their severely underpowered with what I have now.....although they did just break my license plate frame today. and i lost 3/4 screws -.-
haha nice, ya so is mine. its just a 12'' polk but sounds good. i put a piece of styrafoam (i don't know if i spelled it correctly) under my licence plate. it eliminated some rattling and it wont scratch my paint.
