My 993C4 is a regularly used car, not a shrine to originality. I take the view that Porsche built a fantastic car but that in the 20 years that have passed some of it has deteriorated and technology has progressed. I drive the car on occasional long trips (it's been to Le Mans this year - great fun) and will probably visit the South of France next month. On those drives I want to be able to hear the engine and my stereo, but nothing much else. Those of you who think that a Becker through aged Nokia speakers is the only way, please look away now, you won't like this! Anyone who wants to know how good a 993 can sound, please read on...
I have replaced all the speakers (JBL rear, Morel front) and the head-unit (Kenwood) but still found that the sound was disappointing. So sound-proofing was (one of) the logical next step(s). This work and the stereo upgrade was all done by www.enigmaaudio.co.uk in West London, to whom I am very grateful.
The first thing was to remove the door cards. Behind them the old door liner was torn and taped-up with masking tape. Having removed and discarded the old liner, in the door, old "brown bread" insulation that had fallen off the door and was just sitting in the bottom of the door. The pics don't really show that in the door but there was loads of old hard, cracked foam just rattling around inside the bottom of the door.
After each door was cleaned up, the outer skin was lined with sound proofing (stuff like Dynamat but actually http://www.fourmasterscaraudio.co.uk/store/skinz/) as in pic 3 before a dense foam was used to neatly line the door interior. Then each "hole" in the inner skin was covered with skinz before a new door liner was applied and the door cards and fittings replaced.
One of the few things I don't like about my 993 is that at m-way cruising speed there's an irritating drone from the rear bulkhead/engine bay. So we decided to sound proof that as well. The rear seats and interior was removed, Skinz applied to rear bulkhead and sides, lined and all put back together. Simples! (well, simple for me as someone else did it). Pics also attached. The eagled-eyed among you will spot a silver 993 Targa in the background having something else done.
So - what's it like? Well, the first thing is that it is not visible in any way, but it is instantly noticeable. Close the door and the shut is much more solid. Tap the door and the knock is utterly solid. Inside, fire up the engine and whilst the engine noise is surprisingly unaffected, as soon as you start to move you notice a huge reduction in roar noise, rumble & rattle. It's really like a new car. The effect on the stereo is equally profound. Making the doors more of a sound-box lets the Morels work properly. They kick out deeper bass, richer treble and because they are competing with less noise then you don't have to turn the volume up as high. Everything is just better. I've only just got the car back but already I am delighted.
(Had to cut a couple of the pics as I can only add 7)
So, a huge thank you to Sylwester and his team at Enigma Audio.
