97 Tahoe..Couple Issues with Speakers

[SeriousSide97]

Guys my rear passenger door 6.5, I believe, is not working. Also my passenger side front component speakers are not working. Front components were working good, rear 6.5 has never worked. Help me out here. Their all alpines and headunit is El Chamellon JVC.

it is possible your rears were powered by an amp under the driver seat that may have been removed or the power relay for it is not being activated by you head unit.
