I wasn't too happy with the level of bass from stock 6x9 subwoofer, so before splurging on aftermarket subwoofer and amp, decided to see if I could improve the stock setup with a 6.5" subwoofer.
I used DCS165-4 6-1/2" Classic Subwoofer 4 Ohm with 3D printed 6x9 to 6.5" adapter.
Factory box...
Just wondering if anyone has seen this. There is good LTE signal and music apps are working.
I've already tried full reset (15 sec with flasher and far left button).
