I had alittle time to play with my amps yesterday, So I thought I would do my best to adjust the gains.. Turned the Pioneer HU up to about 30 ( My loudest Listining Volume. Then I gently turned my gains up and there it was ( The Coustic amp distorts so bad ) Gain turned up about a 1/5th of the way..Then since my pioneer amp blew up and I had to temporarily use a Fast and Furious amp until I can afford another one my front speakers distort like heck too... I give up ... I think I am just going to pull all that crap out and get me a laptop mount for my truck and just plug it to the pioneer head unit with the front an rear 6x8's ( kickers ) They finally came in and I just installed them Today..
