Rear Bose subwoofer error.

[Jeppesa]

Hi all.

I'm new here and I could use some help.

I've got a caynne 4.5S from 05, with the Bose sound system.

I bought the car about a month ago and found that the subwoofer in the spare wheel compartment was missing!? I have now bought a used Bose subwoofer/bassbox, in working condition (according to the seller).

Issue: when I connect the bassbox, the only thing I can hear coming from the speaker, is a popping noise and no actual sound or bass. And the popping noise is making a "pop" for approximately every second passing - pop, pop, pop, pop, ect... It's not even following the rythm from what's playing on the head-unit.

What can this be?? A faulty speaker or the amp attached to the Bose bassbox?? And how do I find out?

Hope I've got enough info, for you guys to understand.

Any help is much appreciated!

Kind regards, Jeppe

IIRC - this is a rather common failure - of the woofer amp. Usually after it gets wet from a flooded tire-well. Fix is a new amp.

Thanks your reply deilenberger.

I've heard about the flooding issues on the cayenne and is probably why mine was missing in the first place. Quite annoyed to have bought a faulty bassbox, when it was supposed to be fully working though.

Do you by any chance know where I can get a hold of one of these Bose Amps? They do not seem easy to find anywhere.

Thanks,

Jeppe

I saw a few on ebay for ~450 USD

So I've bought a new amp and it was the issue. The subwoofer is working just fine again. However I found it difficult to get hold of an amp from a Porsche Caynne, so after some research I found out, that the Audi A8 models with Bose, use the same amp for the subwoofer. So I ended up buying a whole subwoofer unit for an Audi, to only use the amp from it. SO much cheaper though! And exactly the same amp. Win!

Once again, thanks for the troubleshoot!

Great info on the alternate source for the amp..

Well guess I'll be replacing mine too. I've been noticing my music sounding thinner and thinner week by week. Today I decided to investigate and here we go! Anybody have a working sub or sub amp you'd like to part with?

Hi All!

 

Old post I know but I finally got around to installing a new amp and the sub still doesn't work. Does the new amp need to be coded to the car? Thanks in advance.

okay update. took everything apart and reconnected the new amp. still no joy. did the 1-4-8 reset and the new amp works just fine. just fine enough for me to discover the subwoofer is blown too! gotta love it!

If you can't get hold of any Bose units you could think about changing the sub for an after market item, the 6" Bazooka bass tube fits behind the panel in the boot above the wheel arch with the liner removed. That is if you don't fancy the custom box route, which is a whole lot more hassle and money.

update, I actually got a Bose 5.25" woofer.I bought an old Acoustimass system from a yard sale and the woofers - there are 2 in the bass module - are exactly the same! who knew!?!
