Anybody have this kit?

I am thinking on getting this kit. Wondering where to install the horns. I never carry a spare so the compressor and tank will go underneath the bed behind the axle. Does anybody know of someone here in DFW that could help me install? That has the tools. Thanx and this is my first post. http://www.hornblasters.com/products/details.php?i=shocker-232-train-horn-kit

The good thing about those horns is you can mount them just about anywhere. Just mount them close to the tank and compressor if you are going to mount them Under the bed.

Thanx.
