Hanging alongside those horns at pep boys I saw some horns that had built in compressors and relay etc. They are dual horns that you hook up to each other and then to the stock horn connection. I installed them today and was able to get them into the stock location although pointing downwards. They are pretty damn loud and work great. They are about 10 bucks more expensive than the other ones. I figure the ten bucks was worth the time and wiring they saved me. Have any of yall tried these. I will post pics as soon as I can.
