Hi. Envoy xl. With bose speakers and amp. the head unit is aftermarket. The sound was bad and making some noise and buzzing . The rear speaker's sound is very very bad.
The front was little fine. So I removed the headunit to check the wires (because some times if I pushed the unit back the buzzing and noise go away)
So I found the wires was spliced and tapped padway.
I spent hours searching and reading the wiring diagram.
Its different than what I have .
The current installation and wiring was reversed the front and the rear. So I corrected that but iam still having bad sound and bass. And the rear speakers is still very bad.
Is it related to the low Level wiring?
Any help please. And if anyone have a wiring diagram that will help allot.
