I have a 2004 Silverado duramax with Bose audio system.
I have a jvc kW-10 head unit and 2 jl 10 subwoofers.
Got the bugs worked out with the headunit to factory amp stuff.
For some reason my aftermarket subs are not hitting right. You can hear the factory 10 over the 2 Jl's.
Any help?

Bose licensed it's name to a lot of manufacturers but every one is different. You'd have better luck on a Chevy/Gmc truck forum.

reverse polarity on one of the subs
