So I've installed a new HU. System volume can be turned up to 25 without Bass before it gets fuzzy and the HU turns on then off. With Bass on its highest level, the speakers sound fuzzy at all volumes and the max volume can only be 18 before the HU turns off then on. It also happened with the old HU Is this a power issue? Is there any way to fix this or tell if my alternator needs replaced? With the Bass issue, the speakers are stock so I assume that's the other issue.
