Boston Acoustics Speaker

Hi everybody! I've been lurking here for quite a while, even before I purchased my 2011 IOM 2SS and have always found tons of useful info on the board. Hate for my first post to be a request, but I here it goes..

Took my car into the dealer to get the left rear speaker replaced b/c it was blown. When I go to pick it up, I notice a difference in sound between the left and right. The replaced speaker is noticeably weaker in bass and overall sound. I asked them if they were sure it was the right one and they assured me it was. It was replaced with part #20984302.. And when I go to google it, it seems like that's just the stock speaker. I can't find the part # for a rear Boston Acoustics speaker anywhere. Is that the right part # and could it be something else attributing to the sound difference? Or is there a part # I can give them to make sure I get a BA speaker? Just doesn't sound the same! I hope someone out there can help!

It's the same speaker with the same part number, BA is 2ohm and regular is 4ohm, your speaker might not be hooked up to the factory amp somehow.

I really have no idea though....

You know there is an audio section? I blew through both Boston
6 X 9's and even if under warranty, you'd be better off just buying better quality.

Sorry, I forgot about the audio section.. If I could move it there, I would.

Thanks for the link. It looks like that OP was referring to the front speakers when saying they were the same part #. They then go on to say how different the rear speakers are. I magnified the pics of the rear speakers to get a look at the part #'s, but neither match the part # they put on the paperwork.. After looking at the pics, the stock speaker looks a lot smaller than the BA. Went and looked in the trunk and they look to be the same size.. Must be something else? Not sure.

Is it the driver side 6x9 ?

Check to see if all the wires are connected exactly the same as the passenger side 6x9

Does it cost to get a speaker replaced or is it under warranty?

I've read about a lot of blown speakers. How does it happen? Radio all the way up? Bass all the way up? Or is it just from moderate volume say 20 or 25 on the volume display. I have the BA sound and I'm just wondering what I have to do to avoid blowing out speakers.

It costs your TIME at the dealership.

You take it in. They insist on "checking it out" themselves. (Got to charge that warranty time to GM).

I waited. Almost two hours later, they pull my car up and tell me it IS blown and they have to order it.

When it comes in, another trip to the dealership. ANOTHER two hours waiting for them to replace it.

Two trips. Four hours. No thanks.

if this the case, your speaker is drawing only 1/2 the power from the amp(4ohm resistance vs 2 ohms), thus sounding like 1/2 the volume.

Regular use, in my experience. I don't rely on the rear speakers for bass. I installed a sub amp and box for that.

All the rear speakers have/had do was normal volume and bass.

I kept the BA speakers when I upgraded and installed the sub. Live and learn.

The BA speakers are crap IMO. They will be replaced with Alpines!

It would have been nice if they would have at least went with the Bose system that is in the Tahoes.

Ya, didn't mean to get off the original topic there. If you are noticing a difference in sound quality then I would suggest just replacing them with a better brand.... Save the hassle of wasting time at the dealer etc. etc.

Unless, of course, you are wanting to keep everything factory...

Heck, I would offer you mine but I just got the car..! New speakers and sub is on the to do list though...

Yea they r still under warranty so I figure I'll get them to replace for free (paying my time of course) and if they blow after that I'll just go better quality. It just went for no real reason though, I don't max out the volume ever.

After looking into my speaker problem again, I couldn't really figure out what was going on.. Looked like the same speaker and that it was installed correctly from what I could tell. Then took another look at the paperwork.. The tech's note says he replaced the RIGHT speaker, not the left! Going in there on Monday to give them a piece of my mind and get the left one replaced. UGH!!

LOL!!! "No, I said the other left"

Maybe use passenger side and drivers side instead of left or right when you take it in. Hopefully there will be less confusion when the tech gets a hold of it.

Speakers usually shred because of distortion, not necessarily sheer power. Once the source material overwhelms the amp's ability to output 'clean' power, the power signal to the speaker overwhelms the speaker's capabilities to reproduce sound as we know it and basically melts the voice coil. Older speakers will also fall apart when the foam surround falls apart or when the cone material disintegrates.

It's very, very easy to replace the speakers in the rear deck. Two wires and four fasteners and you lying on your back for a few minutes. I'm quite surprised anyone would waste their time getting stock stuff put back in under warranty when a quality pair doesn't really cost that much.

Hit the tab on the left, "Car Audio..." and select "outfit my car," tell the system what you have now and they show you everything that fits in the various locations. They also include any adapters or wiring harnesses that may be necessary, plus include installation instructions. You can read reviews on anything they have sold more than a few of, too.
