The Explorer needed a louder horn. I usually install air horns from hornblasters.com for other people but since I'm a cheap ass I tossed this system together for my Explorer. The hadley air horns have a great sound that will wake you up with a quickness, they are used on many OEM semi trucks and are a quality product. I also installed an auxiliary air chuck by the receiver hitch, for airing up tires, etc. I have a similar system on my Expedition. I ordered a 3 gallon air tank but couldn't fit the darn thing anywhere, just too long. The only place that would have worked was if I took the muffler off, moved the pipe away from the inner frame rail and welded in a glass pack or something smaller around. Wasn't about to do all that so I settled on a 1 gallon air tank. I have it set to 125 psi, it sounds good and the compressor doesn't work to hard to reach that psi. I initially set it at 150 psi, had about the same sound but the compressor had to work a little longer to get there so 125 psi it is. I ran (2) 1/4" air lines from the tank up to each solenoid, and then teed each solenoid into a pair of horns. This way each horn gets plenty of air flow. You may notice that I used to quick connect air fittings, they have double o-rings and don't leak. Sometimes the standard brass compression fittings leak.
1 gallon air tank mounted in rear, passengers side frame rail.

Extreme Air 150 psi air compressor, mounted in rear, drivers side above exhaust.

A total of 4 Hadley bully series air horns, 2 mounted under the hood. I made a bracket that mounts everything to the power steering bracket with 2 bolts. Also another 2 of the Hadley's behind the front bumper cover, driver's side. I wanted all 4 behind the bumper cover but couldn't fit them unless they were seen or I removed the windshield washer reservoir which I wasn't going to do.

Behind front bumper cover, a bracket I made that holds the 2 Hadley horns and two 12 volt air solenoids.

Of course it all has to be wired correctly and clean or it ain't going on my truck. 30 amp fused relay to 12 volt compressor (switch key on power) 30 amp fused relay for 12 volt air solenoids. All wires loomed, heat shrink, etc.

Auxiliary air chuck.
