I think I have narrowed an issue down to my horn, I get a static sound that goes away when I turn the horn off. I know how to make a sub dance and test a speaker but is there a special way to test a horn? My friend has a tone generator (9 volt, alligator clips and a button to make it beep) I can use to test speaker lines, I am thinking this is the only way to test a midrange. Is there a better method or easier method so I do not have to drive over to buddy's shop. I am trying to find out if the static is coming from the mid range or if it is an issue in the crossover, the cross over is fairly simple though so I am thinking it is the mid range. I already opened the cabinet and checked all the connections, the spades were all secure, I reset a couple of them. The tweeter control is soldered on; the joints are all shiny. Thanks in advance!
