Best Christmas Gift Ever....

Amazing kit... My father and brother decide to surprise me with this kit after I mentioned buying one after the holidays. Tried to get it set up the weekend after Christmas but ran into a couple of snags. Finally got it installed yesterday and I love it (pretty sure my neighbors might hate me sooner or later) it's loud and gets it's point across.. easy as pie to install but I do recommend having an extra set of hands around if you can. Got it done in about 4 hours by myself. Tank and compressor are in bed of my Ram 1500 and horns are behind front bumper on a plate secured to Tow Hook mounts at front of frame. I absolutely recommend this kit to anyone looking to make some noise, protect their investment and have a few laughs...

Conductor's Special 232 Kit

I absolutely LOVE this horn! It literally blows the competition away, everyone that has heard it tells me it is by far the loudest horn they've encountered. Every step of the way - from advice on what to purchase, explaining in detail the specific parts I needed, installation, even returning some items that didn't work out (completely my fault) - you guys have been so helpful and made this process a breeze. I can't recommend you highly enough, and already have. Thank you!
