I have very low sound coming from backdoor speakers and tailgate speakers.
It was stock radio for Toyota made by Panasonic (non JBL). This is way to expensive radio to have these types of problems. Please help or I will be sending this radio back. Please see attached picture of build.
Maybe something is wired incorrect or I didn't get all the wires. Since so directions on wiring were included with my radio I could be missing something. Please help ASAP because I don't want to send the unit back.
