Installed kenwood DNX570 and Kicker speakers from Double D. I love the system but the stock Bose components seem to have a problem - likely was there before the install. No signal to the passenger door woofer from the 100W amp. There is signal to the 3.5" and the other speakers work fine. The speaker tests fine.
Have tried a diff. 100W with no effect and then a diff. BCM - no effect. Where to look next? Thanks
What interface adapter are you using? Make sure all plugs are seated properly.
Swap entire door sub/3.5 setup LH/RH and see if problem moves. If it moves the issue is in speaker/amp, if it stays problem is power/signal getting there.
