1. Put a tractor trailer horn on the vehicle.
2. Purchasing a higher decibel horn is the way to make your car louder. Air horns are nice too. Check you local car parts place for aftermarket horns. Link below for example.
3. my friend had one and it was pritty expensive .... its an air horn... he needed to install a compreesor too.. good luck..
4. ive done it before and it was awsome all you need is a tank that will hold at 80 pounds of air some 15 feet of air hose a air compressor that can supply a tire 35 pounds of air in about 2 to 3 minutes cause those horns take a lot of air and a switch that turns off the compressor and you got it made and you will need a switch to activate the horn but you will have a laught or a really good time but make sure you have the space for the horn
