You might add this link to your other post instead of pics. The horns sound great. Nice truck and install!
Those sound pretty dang good. One thing - you have a few wires passing through a hole in the frame. I would protect any wires going through a metal hole. You can use a grommet, split loom, or even wrap some layers of tape.
Nice install - I think you need a bigger truck!
Cool install, only one other small thing, you may eventually have possible trouble with your compressor. I have two customers who mounted their compressors on the side, and what it does is wear the piston ring un-evenly on one side as opposed to having the compressor upright. Other than that, them Horns sounded sweet!
Thanks for the suggestions. Those are very good points. I have my new 5 gallon tank coming in today, so I will be separating the compressor from the old tank. I will try to figure a way to mount the compressor straight up and down. Also when I go back under there I planned on running wire loom from the back to the front on all the wires.
