I find it ODD that GM uses that same part number for several DIFFERENT cabinets (Cobalt, G5, HHR) but I have seen them listed this way. The Cobalt /G5 version looks like a more compact version of the HHR cabinet. Cleaner, and more streamline I guess you could say. Has anyone tried one of these Cobalt units out for an HHR? Does anyone have a cabinet for sale? If so, please PM me with pricing. Located in Georgia
Thanks!!! 2nd HHR, but my first PANEL & my first post!


Upon digging a little more, it appears the correct GM assy number is 15906941..... also on the Pioneer decal

 

The GM part number is 15906941, fits all HHRs, and nothing else. I don't know who makes the part you're looking at. The number has too many digits, and no results on GM parts sites.

 

After posting, I believe the other number I posted is a Pioneer reference of some sort.

 

Are we to guess that you are talking about the woofer cabinet?
