hi all i got a 03 tl es sedan and am doing up the sound system can anyone help me out with info about where to run the power lines through the firewall for a subwoofer. thanks in advance guys

you can run the power through a grommet next to the engine bay fuse housing OR there's another one right next to the firewall on the passenger side that you can run down into the passenger foot well. from there it's as simple as tucking it in under the carpet, up and under the back seat and through a small gap in the wall splitting the cabin and the boot.

Easiest way is to use the large grommet on the left side of the p/side footwell. Then you can run it under the inner guard straight up to the batter. (Easiest way I found).

ok got it sorted thanks guys. just hope this post helps someone else in the future lol
