    Reading 25% both sides for some reason. When I’m back home I’ll double check with carb cleaner and probably just to the intake gaskets.

    2004 tahoe speaker whining/squealing

    Mine started to squeal as well but I thought it would be an amp or wiring issue. Could it just be that the speakers are that bad?

    Sub Woofer Addition Wiring

    Hey I was just reading through here and I’m gonna put subs in my Tahoe as well. Just to clarify that harness adapter makes it so the lines aren’t amplified and you could then have your sub on its own amp and speakers on the Bose still?
