Hey guys,
I installed a Rockville RW10CA slim powered sub in the cargo area of my 2014 Tahoe LT with factory Bose system.
Started with high-level harness tapped into rear speakers — had green power LED but zero bass.
Switched to a Metra WM-LOCKN LOC with RCA to the sub’s low-level inputs.
Added remote wire to Fuse #16 (AUX PWR), good power/ground, checked both the sub’s 25A fuse and inline fuse (both look fine).
Now I’m getting zero power to the sub at all (green LED completely off), even with the LOC unplugged.
Tried flipping polarity, re-checked all connections, fuses look good, wires are tight.
Anyone seen this on a GM Bose system?
Did switching to the LOC kill the power somehow?
Common ground/power issue? Or should I just take it to a shop at this point?
