So, I've finally got myself a pair of Alpine speakers to replace both dash and rear originals. Slight issue though.
Someone has already put some replacements in the rear. The originals are long gone with the "new" speakers held in with a combination of screws and gaffer tape....
I'm therefore looking for a pair of old speakers to be able to mount the Alpines properly. Anyone got some?
Also, what was the verdict on replacing the door speakers? Worthwhile or not?

Cheers

Can't help with the old speakers, but I have a Conntinental DAB headunit with the Alpines front and rear, original door speakers. I think it's pretty decent - loads better than stock.

Not sure I'd bother going any further as my car is pretty noisy, so little real benefit.

That's done, had to be when I swapped to the Becker.



Mixed score for BMW- correct pins, wrong plug:



Mr Damnmit,
Did they supply the wrong plug or was it the wrong part ordered ?

Both- their parts guy pointed to the correct plug on his diagram and confidently entered the wrong part number in his order system.

I should probably update this thread.

I swapped out the Hertz speakers in the dash for Morel Virtus 402 midrange and separate tweeter units - silk dome rather than the butyl of the Hertz was one of the things that the audio chap mentioned.

I also had the Focal sub fitted, it's under the dash on the passenger side.

Very happy with how it all sounds now - but still a bit frustrated at the radio reception of the Becker, which is excellent at playing CD's, but seems to struggle to hold onto Radio 4.

Dammit,
Did you use the BMW sourced socket ultimately? If so can you provide the definitive part numbers for the shell and pins please.

With regards to your radio reception, the aerial on the 996 are amplified and need to be powered, does the aerial adaptor you're using provide power to it? Also it isn't unknown for the aerial amplifier to stop working, someone with access to the parts catalogue can help with the numbers.

Was it worth swapping to the Morel speakers? The 996 is quite noisy.

The antenna amplifier is new, was changed as part of the troubleshooting process. Are you saying that the amplifier is powered from the stereo?

I can't recall where I got the socket from in the end (unless I mentioned it in this thread?), I might have a spare - will have a look.

The parts are available, is the good news.

I like the Morels - and bear in mind that my car has no roof, so however noisy yours is, I suspect mine might be worse!

You probably used something similar to this :


The blue wire needs to be connected to +ve ignition on or the electric aerial connection on your HU. It powers the active aerial bit (aerial amplifier)

I don't intend spending lots of money on the audio on my 911, it just needs to sound reasonable, at the moment it isn't, I may have to go down the road of taking the Bose stuff out, the amplifier, the sub and the speakers in the dash. If I can avoid it I will. I don't like altering the original wiring loom so would like to buy or make my own adaptor harness.

Mine is a 2001 996.2 C2 & like the OP's is also pre MOST. However mine left the factory without Bose.

I've upgraded bits in several stages. The 1st was to replace the Becker with a Pioneer carplay unit. The Pioneer's internal amp driving the standard speakers made a significant improvement.

The next upgrade entailed replacing the standard speakers with Alpine's, still driven by the internal amp in the headunit. This was a further improvement, but perhaps not as big a leap as replacing the Becker.

Last but not least, I added a focal active sub, & some dynamat type stuff in the cavity behind the rear speakers. To my ears, it now sounds as good if not better than some "high end" systems I've heard from other vendors (bose, harmon kardon, mark levinson to name a few).

Based on my experience, I suspect the internal amp in your Alpine headunit will adequately drive 2 pairs of speakers. You may want to consider disconnecting the existing speakers from the bose amp, & running some cables to join to these. If you're still not happy with the results, then it would be easy to revert or you could consider replacing the amp, & won't have wasted much beyond some extra cables & your time.

If you have a 3rd pair of speakers (eg lower doors) or bose sub(not sure if this is active or passive?), then you'll obviously need another amp if you want to retain the use of these.

Another option is an active sub like the Focal. They sell two versions (ibus 20 & ibus 2.1). The ibus20 is an active sub. As the name implies the ibus 2.1 is effectively the same unit with an additional internal amp that can be used to drive another pair of speakers. This might be a simple option to allow you to add an active sub, & drive a pair of door speakers, while driving the dash & rear speakers from the headunit.

The Bose sub has its own amp located within the unit. It can be driven directly by an aftermarket head unit with an adapted lead.

I’m clueless with audio install, but do love good sound (especially a bit of bass).

Does anyone know an audio place in London that knows 996 that can sort me out?

I have a 2001 996 C4, with dash and rear speakers. No door speakers or under seat sub (that I know of).

I recently used Auto Audio in Park Royal and was impressed.

I also have spare a rear BOSE subwoofer, i dont have an amplifier in mine.

In my old 996 I used the Pioneer head unit to drive the sub. The Pioneer had a genuine sub output by bridging the rear speaker outputs.
I replaced the speakers in the sub to get the correct 2 Ohm impedance required by the headunit..

It actually worked very well.. The Sub is currently sat on a shelf in my garage..
