     I wrote something up about the subwoofer setup and I will paste it to 
     this email after this...
     
     My entire system is VERY simple in concept. It quite possibly sounds 
     better then any you've ever heard (especially considering that the car 
     itself has not been compromised, in any way). This car can be returned 
     to the factory system by simply putting the front kickpanel speakers 
     back in, the rear speakers, the radio, and plugging everything in. I 
     will be posting pictures of the speaker setup (front and rear), as 
     well as. a not to scale drawing of the rear setup to my web 
     page...soon (I need to drop the film off to be scanned). 
     
     My system: 
     - (1) Alpine 7930 CD/Tuner (not top of line)
     - (1pr) DynAudio System 240 (7" mid and tweeter...really need to see 
     the pics on this part)
     - (1pr) Rockford Fosgate Power 10's (see below for details)
     - (2)   Rockford Fosgate 400x4 (bridged to 2-channels, each. Using the 
     x-cards for crossovers)
     - lots of Dynamat, lots of fabricated pieces (underside of rear deck, 
     kickpanels, amp rack)
     - good wire 
     
     *Notice: NO processors/equalizers/external crossovers...I might add a 
     1/3 octave (trunk mount) eq to fine tune the system (but it really 
     doesn't need it). 
     
     Here's the pasted part>>>>
     
     What I have is custom built by Woody's Car Audio in Arlington, Texas. 
     Woody's has done 3 (maybe working on number 4 now) E36 cars exactly 
     like this (mine, a '95 Dinan Supercharged M3 and the contest winner 
     car of a 45 year old business man, and one fabrication to be shipped 
     to a Mr. Avery from this list and to be installed by his shop). But 
     the basic Aperiodic setup is nothing new (I've read a white paper on 
     it from 30 years ago). You can read about a store bought version of 
     this type of system at Dynamat's web site (their version isn't pretty 
     but the concept and sound would be the same) www.dynamat.com. 
     
     When you look in my trunk you see (2) Rockford Fosgate Power 10 
     woofers (these are designed to be used in the sealed enclosure) 
     mounted were the factory rears used to be be farther back to clear the 
     shock towers. These are mounted against a ring shaped cutout of the 
     MDF that is carpeted to match the trunk liner, this ring is then 
     mounted to a piece of MDF that completely covers the underside of the 
     stock rear deck (2 pieces with a seam down the middle), also carpeted 
     to match and routed to look nicer. The entire deck is covered this way 
     to damp to metal and reduce vibrations and resonances. Above the false 
     deck (you can't see this) is the membrane material with speaker cloth 
     on each side (it's a fiberglass material and this keeps the stuff 
     together) and it's sandwiched between the top side of the false deck 
     and one more MDF ring...it's all bolted together with long bolts from 
     the top down through the speaker mounting holes and double nutted. 
     
     Inside the car: stock rear deck, no metal was cut...recommend removing 
     the stock deck and Dynamat-ing the metal underneath then re-install. 
     All the sound plays through the stock grills. No rattles, NO EXCUSES, 
     VERY IMPRESSIVE. 
     
     Cost: Woody's charges $1500 for the rear deck (installed) including 
     the Fosgate Speakers which are about $250 each (this excludes 
     Dynamating the inside the car metal and any other equipment like amps 
     to drive them). I don't know how much the Dynamat version is??? I'm 
     not sure how much they charged David Avery for a build and ship 
     version. I do know that they need to make a template off an actual 
     vehicle (if it's not an E36 coupe). 
     
     I love the sound of my bass (tight, accurate), but my car system 
     really outshines ALL on the mids and highs...yet another story and 
     another $1500. The only thing left for me to do to this system is a 
     1/3 octave equalizer (in the trunk - "set it, forget it") to fine tune 
     some of the resonances of the car interior, and possibly a better CD 
     player (maybe something with an outboard DAC). My car stereo sounds 
     better then all but the finest home applications...trust me I'm into 
     this even more then the car stuff!!! It is one of the best sounding 
     systems I've ever heard in a car, including some really mega buck 
     (ruin the car) stuff...my car is NOT compromised AT ALL, and my trunk 
     is fully functional...as is my right foot. 
     
     This car is NO garage queen either, I do drivers schools and 
     autocrosses...

Hi Dean,
I tried emailing you the other day about your bass solution for your E36, but my email bounced.
I'd be very interested in more details about your car stereo, both for my knowledge and for others via my E36 homepage www.unofficialbmw.com/e36.html

thanks
Dale
