so here goes:
I have hifi not logic 7 no I drive professional hu, no fuse on amp, Bluetooth with auxiliary in middle cup holder area.
was on a trip and using a DC converter when (unknown if coincidence) my speakers stopped working as well as my 12v fuse blew
I replaced the fuse and 12v works but no audio sound at all.
checked the radio fuses (all 3) all are good.
couldn't find anything burnt or anything.
thought it was my amp, bought a replacement (exact model) plugged it in and still nothing.
then thought the mulf unit went out, bought a optical jumper and jumped the fiber optic to the unit (in trunk under mat in middle), nothing. I had a spare stereo HU (aftermarket) and adapter so I plugged in just the speaker cables from the HU and left my stock HU connected at the same time and still no sound ( not my HU i guess).
the one thing is that there is no light from the fiber cable that goes to the HU, so what else is in the MOST loop? am I missing something somewhere?
