Amp Cuts Out With Volume
|
New member Username: JdgrahamPost Number: 1 Registered: Jul-09 | I just put in my sound system and all was working well until yesterday when I hit 140 on the highway and the amp cut out and has been ever since once I turn up the volume. I also noticed that my sub is rattling now and it wasn't before. Please help, confused as to wether or not its a blown fuse, blown sub, or wiring. Thanks. Ps. When I eliminate the bass/sub and blast the speakers they still pump good clean sound and the amp doesn't cut out. |

This is what i use to set my gains, i tune it with the dmm first, then by ear afterward and make sure it still sounds good. http://web.archive.org/web/20080104010047/http://www.subwoofertools.com/forum/se tgain.asp |
