Need help... Trailblazer SS BTA8100FHC
I just purchased and installed 8" amplified Bazooka in my 2007 Trailblazer SS. I have factory radio and using the FAST -9999 to connect to the factory wire harness behind the radio. Everything looks to be connected correctly but I get very little sound of the tube only no other speakers play even with the radio full volume. I turn off radio and disconnect the FAST 9999 and the radio plays correctly. What am I missing?
