W203 Coupe Parts - Performance Pulley & Stealth Box w/Sub & Amp
Thanks, Dave
1. Custom machined crank pulley to increase supercharger boost and inflate that "smiles per mile" ratio. Slightly larger than any other pulley offered on the market. GREATLY improves performance!! Belt included and no core charge, you keep your stock pulley! About 20K trouble-free miles it. No computer retune needed! Will fit 2000, 2001 & 2002 C230 Kompressor coupes, sedans and SLK's with the 2.3 liter engine.
$200 plus shipping

2. Wanna add some bass to your coupe, but don't want to lose any hatch space? Here's your answer. A custom made fiberglass enclosure with a Pioneer Premier 12" sub that fits in the stock Bose sub box space and Alpine MRV-T320 amp that fits inside your spare tire wheel. Dramatically improves the sound without loosing any space at all! Includes all Monster Cable wires and Pac high to low level converter for an easy 3 wire hook up. I can help with wire colors and placement if needed. These were listened to at "conservative volumes", but tested to reveal surprisingly high output and sound quality. I am positive you will be very pleasantly surprised! Surely this could also be installed in a non-Bose coupe also, but wire hookups will most likely vary and could require a longer RCA cable.
$450 plus shipping (shown installed for proof of stealth fitment)

I honestly hadn't thought of selling the amp separate from the sub & enclosure as they have been matched to work with each other (i.e. gains, inputs and eq's set). I just figured it would be a nice "plug and play" setup for anyone looking to add bass to their coupe. Hit me up with a PM though as I may have something that might work for you.

for clarification purposes, is that a crank pulley or a supercharger pulley? they are NOT the same thing.
supercharger pulley is machine down and sits on s/c to get more boost
crank pulley sits on crank and is larger to generate more boost and to spin s/c pulley faster
The accessory ribbed area has not been modified from the stock diameter.
The aluminum ring near the front of the pulley has been machined to accept a ribbed serpentine belt that spins the supercharger. The black part of the pulley shows the stock diameter. This pulley works with the stock supercharger pulley just as the ASP performance pulley does. I have altered my original post in hopes of a more correct description. Sorry for any confusion.
Nice "signature movie" BTW!

I believe the 2.3 liter engines were in 2000, 2001 and 2002 coupes, sedans and SLK's.

No problems with heat build-up in the amp? Did you run the amp in that location with all of the normal parts of the floor on top of it?
