E38 audio upgrade

[1989 e3o]

My car has "dsp" but only has 2 rear deck speakers or subwoofers. I was under the impression that it should have 4. Both of mine are blown (old age and p.o.) I want to replace them but was hoping the bav sound kit included them. Do I need to find 8 oms rear subs?

I would consider this as well but being in Canada the cost of getting them here is brutal

[SawwuceBawse]

I would consider participating in a group buy. But I can't imagine it being more than 10% off

[BAVSOUND]

For those of you who mentioned interest in the group buy, I did get authorization to do 20% off, as well as free shipping assuming we can get 10 interested parties. This means $400 shipped to your door. See the thread below for full details!

Can anyone give me an update on there experience with bavsound the company and how there speakers sound in an e38?
As well as some advice on what to replace the rear deck subs with and I would like to keep the factory box setup

[Carcraz8]

Anyone?

You need to search around a bit to find some feedback on the Bavsound upgrade. I beleive the reviews are largely positive, but the difference befween the new speakers and your factory speakers is not enormous if your factory speakers are not shot with bad surrounds.

For the rear deck sub search "Monsoon upgrade" or find the "how I got deep bass from my factory enclosure" thread by dville. Basically get four VW Monsoon speakers from the junkyard for cheap and install them in the factory enclosure for a big difference in sound.

I still need to do this upgrade.

Has anyone unplugged the 3/4" tweeters and just ran 1" and 5.25" component sets in their car? Do i really need the 3/4" speakers?

And yes, I know I'm being cheap lol

I refoamed my 4 door speakers surrounds (until I get some funds up for an upgrade etc.)... the refoam kit off ebay is like $30, I hammer my speakers and no problems with it .... you'll need the measurements from the speakers in the doors, if you do a complete refoam pull all 4 door speakers and get them all done at the same time or the glue can go bad.....

Mine are all deteriorated so I'm replacing everything but 3/4s in front. I'm just wondering if you really lose the highs by unplugging. If so, I'll order new ones too

3/4" is that the tweeters? depends factory amplifier has separate amplifiers (12 separate discrete amplified channels are in the dsp amplifier dsp unit total) for the woofers mids and highs up front if it's all factory unplugging the tweeters you will lose highs if it's the mids that are "3/4s in front" my guess is it may sound a bit like the rear seating areas but I believe the highs up front factory may not be exactly as high as the rears not sure though.....removing the mids up front (not recommended) but may sound a bit crisper up front is my guess.....

So the front doors on DSP have one 5.25" mid woofer and two tweeters (1" and .75"). Seems like one is for mid highs and other high highs. I guess I'll give it a go and see how it sounds

so uh the 0.750" driver is actually a tweeter huh ok then with that speaker unplugged there will be loss of treble definitely will need another one if that's the issue, with the 1" driver there will be a loss of coherency if the 1" mid range is unplugged in the the midrange freq. ..... in the front upper driver assembly the tweeter is the smallest driver / speaker.....

Ahhh ok. I thought the 5.25" was midrange and those both high. I'll check the condition of 0.75". If it's shot, I'll leave for now and upgrade the rest then order.

These damn luxury cars have too many speakers! AND for some reason BMWs loves to use speaker material that crumbles with sun. Appreciate the help!

Talk about revival of an old thread... This is what I decided to go with and 3 years later, the speakers still work great and added an Alpine MRV-M500 amp with 12" sub (way overkill for the setup). These speakers are likely no longer available BUT, at least you can get the specs and find something close if needed to accomplish what I did.

how did you put the sub in the car? in the trunk facing thru the rear center armrest or rear shelf area, that's what's keeping me from putting a 12"subwoofer in the car not sure about the best way to get it installed....

I have a ported box facing the trunk with an Alpine 12 and combined with the Alpine MRV-M500 mono amp, it is PLENTY loud. I don't blast my music with the windows down so everyone can hear... and even then I keep the remote gain set < 1/4 for balance but the sub really is overkill. the 250w amp would have been a better pick Since I have yet to listen to the sub with the gain at 1/2 or above as it drowns out the speakers very easily.

nice to hear about that placement can be covert with no mods etc. I might have to install some older stuff I still have..... rockford fosgate 200x2 run in mono just a 12" subwoofer with it ..... for freeway driving or out my area drives etc.
