A while back i had music playing pretty loud in my car ('95 Q45) and i heard my rear speaker behind the back seats start to buzz. now when ever their is a loud bass drum or bass guitar or something it will buzz. it doesnt distort other stuff just for lots of punchy bass.

does anyone know a good place to replace this speaker or how much it will cost?

Amp or speaker? Have you examined both?

i have some good condition factory BOSE rear speakers (6X9). I can also rebuild most BOSE amp failures. email me if interested.

I have the same issue. An 808 kick spells disaster.

I'm thinking of just replacing the whole shebang with something AM.

Do they need to be factory or will any 6x9s do? I am having a similar experience.

The amps are built in and designed for each speaker. If the foam surround is bad, seems like a kit wouild be available.

Please note that the factory Bose 6x9's are 2 ohm jobs. An aftermarket 6x9, regardless of brand name, would work, but they are of higher impedance (4-8 ohms) and the factory Bose amps that are installed over the magnets would not drive the aftermarket speakers well. I tried 6x9 Kenwood 6 ohm replacements for my '94Q, but replaced them with used Bose 6x9s because the door speakers, in great condition, would simply overpower the rear deck ones. So, this was merely a temporary solution, just to get some tunes.

They will work, but at low volume, meaning you won't be happy with the result.

There are usually original Bose 6x9's available on eBay, sometimes cheaper than the re-foam kits available. Hold out for a donor set, if you're going to keep the head uniit and other Bose speakers in place.

Good Luck!

Actually the factory speakers are considered 1 ohm speakers, but to be specific, they are usually around 1.3-ish most of the time. Regardless, yes, they are way different than what is in the aftermarket.

Anyway, to the original poster, the amps are tuned specifically for the Bose speaker, so just as was said before - you will get poor results using anything other than the correct speaker due to that, as well as due to simple fitament mechanics.Simply hit your local pullapart. 89-94 Maximas, J30's, and many Bose equipped GM cars have the same 6X9 drivers.

However, before you simply assume the problem is the speaker, remove it from the system and test it independently from the car (with a home stereo). Also check impedence as well as do a smooth cone travel test.

If it is good under these conditions, your problem is the amp. If you need to replace that, make sure you use an exact match, as all equalization is built in to the amp, and is specific to the part #. In other words, every Bose amp is tuned for the car it is in and it's location in the car (front or rear). Using whatever you can find (amp wise) will result in poor performance.
