Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
Once you find that it is working (if not, check the connection on the side of the box behind the passenger seat) play with the fader until it's thumping is to your satisfaction, and enjoy.

If you still have questions about the operation of the rear speakers you know you can fade the sound totally to the rear and check the operation/sound.

I have taken the rear speaker out for a week or two a few times, and the bass response doesn't change dramatically.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

My base doesn't seem to strong. The rear speaker between the seats has some air movement but no sound. Is this working? thank you, James

POST 2Original post

If air's moving, the mid-mounted sub is working. The Bose system (or the "Blows" system, as I've seen it referred to) is really not that great. I assume you also have the door-mounted subs? I have taken the rear speaker out for a week or two a few times, and the bass response doesn't change dramatically. It does contribute, but not to the extent you'd imagine it would, given its presence in the cabin. So, the good news is that yes, it's probably working... the bad news is you own the same crappy stereo I own.

POST 3 / ORIGINAL POSTEROriginal post

best, James

POST 4Original post

Isn't the impedence different for Bose than other speakers? IE we can't just remove / replace the Bose speakers with whatever your fav replacement is?

POST 5Original post

If you still have questions about the operation of the rear speakers you know you can fade the sound totally to the rear and check the operation/sound. Remember, the rear shelf speaker is a base/sub module. The sounds from it are in those frequences, don't expect mids or highs. Once you find that it is working (if not, check the connection on the side of the box behind the passenger seat) play with the fader until it's thumping is to your satisfaction, and enjoy. :dance:
