Who's got 'em? I'm interested. Let's see some pics of where you mounted the air tank, compressor canister and horns.

 

i had a buddy who had large tires on his truck, so there was no spare- the horns and compressor were mounted around there. i think the tank was there too.
be sure to mount it facing backwards if behind the cab or in some way where its not going to blow your ears out when you toot it...

 

I want a set to alert those pesky cell phone drivers to get off the phone and stop blocking me.

 

I thought bout puttin a set on mine as well an thought bout putting the horns under the bed on either the pass or drivers side. I've got my PA speaker under there an it stays pretty clean and it's up and outta the way.

 

Actually just sold mine to a buddy... buuuut, they were mounted on the roof; looked pretty good, but not the best idea. The compressor was behind the seat, which was fine, but was loud when refilling the tank. The guy who bought mine will be mounting them vertically on his headache rack with the compressor in a toolbox. Loud as heck and oh so fun, I already miss em.

 

I put a set on my dodge. The horns are under the passanger floor facing backwards so the dont fill up with road debris, the tank is in front of the passanger side back tire between the bed side and the frame rail, the compressor is in the toolbox. I had pictures but my phone decided to clear them all off my memory card so I dont have then anymore. If you do it get a big enough compressor and tank so that it would work for onboard air. You dont realize how much you will use it until you have it. I have a viair 480c and a 4 gallon tank its an awesome compressor. It will go to 200psi which is to high mine is switched at 150 psi. I can run air tools to change tires and such if I need to. I am going to run a line to the front and the back of my truck and have a chuck on either end just in case lol. My horns aren't the loudest but they work. I found a set in a petro truckstop in North Carolina the other day that were 156db! They were a triple horn setup with the solenoid for $109. I will try and take some more pics and put them up.

 

Here are a few pictures of the hornblasters.com Conductors Special 540 horns that I have installed on my truck.

 

Thats not fair. You took your front tank out! Im trying to find where to put mine. Got mine from hornblasters too. I love em'.

 

I'm getting these.
