The remote wire was the easiest part of my install so far. Tapped into the fuse box and ran it under the weather seal for the doors under the rear seat into the trunk, took about 5 min.
I'm still trying to figure out the best place to tap into the speakers for input. I see others only tapping into 1 channel, but I'd like to tap into both as my amp has inputs for both right and left and I assume it combines them into the mono output to the sub. I'd also like to mount the loc somewhere where it is fairly easily accessible for tuning.
