2. Alpine Parrot bluetooth unit KCE-400BT with external mic
3. Alpine Imprint sound processor unit PXA-H100

5. 2 x Jehnhert custom door cards with extra mids, replacement tweeters and tuned specific to car crossovers.

Woofers per side:   4 x 165 mm (6,5") JEHNERT »POWER WOOFER«   
Midrange drivers per side:   1 x 100 mm (4") High-End-midrange driver   
Tweeter per side:   1 x 26 mm (1") Neodymium-Dome Tweeter

Excellent sound quality without the need for any sub bass. This system does it all, even with the top down - I'm very happy with results

Couple of pics - Some a bit fuzzy sorry.

New headunit in place, no power yet but screen on right looks great in red when powered up


Door card out waiting for prep


Ouch, in with the drills


New enclosure ready for speakers


Speakers and crossover in place from behind


Speakers from front view


Amp in place before wiring


Dynamat in doors. Not only helps with sound quality but adds that deep 'thump' when closing the doors


Door card complete and back in place


Other side


Fantastic sound, love it!!

Looks great, but I fear you will be giving Joe Type R expensive ideas for his Clio.  I take it you had this done by a specialist rather than fitting yourself, unless you now have a Range Rover in the garage.

Looks good but what are you going to be blasting out with it?

My ipod is full of stuff. I have a very wide range of musical likes

And with that system you'll have a wide range of coverage too! We'll hear the sound system long before we hear the car coming Phil

Since you are our illustrious leader and gaffer we should be allowed to chose the song that is playing as you drive into the car park for the AGM with the windows down.

I shall propose Snooker Loopy by Chas and Dave.

Thats some install, was it following a recommended set-up or were the components your own choice?

As the Z4 is quite a difficult car to fill with sound due to size and lack of speaker fitment space (dare say a Cobra would be the same too) I researched components quite a lot. The Jehnert speaker equipment was the heart of the system and without that I would not have bothered with such an install.

Found out about Jehnert via forums and then was recommended them by the guys at Western Car Radio in Bristol.
