The Impossible Has Been Done
The C4 is not very speaker friendly. The later ones don't even have facilities for door speakers... we are stuck with those damned enclosures on the floor.
However, this is what happens when one gets desparate enough to do something radical.
The speakers are Canton Pullman RS3's. I have had these around for a very long time - bought my first set of Cantons back in 1994!! These drivers date to about 1997.
The set consists of a (nominal) 6" midbass, 4" midrange and a 1" tweeter.
The door installs varied from hard to easy. The drivers side was done by removing the carpeted piece. It is held in by several 9/32" nut headed screws. Once out, remove the carpet, cut out a hole, then mount a 5/8" thick baffle made of partical board. Cover the plastic in 1/2" thick foam and cover that and the baffle in tan suede cloth. All the while, using copious amounts of 3M spray on contact cement...
The tweets are easy... I just upolstered them in tan speaker grill material, drilled a hole, and hot glued them in from the back.
Running wires is EASY... the door channel is open. It don't get any easier.
The passengers door is a bit harder. Due to the contours... I took the same baffle from the drivers side (made 2) and attached some cardboard to it to make a cylinder. Then covered it in fiberglass! the hole was cut into the plastic to make a stand off for the speaker. The plastic was then covered in foam and the panel covered in the same fabric. The speaker pod is then hotglued to the door panel. I do want to redo this because the upolstery job was a bit "off". I want to contour the speaker into the plastic with some bondo.
The floor enclosures are made of 3/4" thick mdf and 1/4" plywood. I coated them in fibreglass and then foamed and covered in the same fabric. The backs got treated with some dynomat as did the insides of the rocker panels.
All said and done, the system sounds so alive, so vibrant. It's insane.
The sound stage is RIGHT THERE. I have never heard such a vivid and clear soundstage.
The crossover points are just perfect. Listening to Rod Stewarts "American Standards" CDs is a delight. The bass is present and accounted for... so subtle, so perfect, so tight. The mids are strong, but not overpowering, and the highs are delicate.
I also have sampled some Metallica - S&M to be exact. There were passages of the Symphany that I had never heard before! Strings that I knew were there, are now there - in spades!
Just beautiful... I am at a loss for words here.
I have no rear fill... just a 10" JL Audio 10W3V2. I am thinking a better sub is in order. JL 10W6V2 may just do the trick.
If anyone would like to do this, I can help ya... just send me the midranges, and the little panels in the doors. I can also build up the enclosures for the floor. It will require cutting the rocker covers. Sorry.
The rest of the system:
JL Audio 10W3V2 10" sub
JL Audio 500/5 amp. 5 channels, of which I am only using 3. 100x2 (front); 25x2 (rear fill or bi-amped tweeters); 250x1 (sub)
currently, I have a nasty looking box of 3/4" mdf. My goal is the sub in the storage bin... Before that, I am going to tune the box some... I don't have the spare $$ for a sheet of MDF right now (the problem of being unemployed, on the other hand, it gave me the time to do this).
I will add this to the FAQ!

The fabric I used is "Suede Cloth". Looks like leather, but it's only 6.00 a yard!
Bogus - next time you do a project like this, please let me know. We manufacture cloth exactly like that in any color imaginable... And I would charge you $0/yard. All I'd need is a swatch to match it up, and I'd send it to you... I've got enough of this stuff to cover from here to Europe!











I would love to hear that.
