Hi All, I've currently upgraded my facelift CLK with COMAND and I added the Fiscon pro on the weekend, replacing the existing UHI and iPod setup, as it was getting a little clunky. All working nicely. My next step is to look at upgrading the audio to another stage, nothing thundering and I don't want to upset the exist loom and hack it up. My main goal is a little more bass, clarity and volume. Ultimately I would be happy to retrofit the harmon kardon setup to the car, which would be time consuming, but essentially too pricey to add to a car which is getting on a bit. This is my thinking: Speakers and Amps I currently have Morel maximos in the 'front speakers' of the car, as well as the tweeters and crossovers installed. These work fine. I have a brand new and unopened rockford fostage punch amp (PBR300X4) sitting in storage which I never got round to fitting to a prevoius car. I am thinking of using this to amplify the system, but again - i don't want to hack the loom up. My current thinking is to purchase a quadlock extension, cut and intercept the speaker wires coming OUT of COMAND, INTO the amp and back out through the original wires of the loom. My assumption will be that the factory speaker wires should be suffient to handle the extra power the amp supplies (and I don't want to strip the car for this). Subwoofer: Currently considering an active sub (yes, I know another amp somewhere) such as a pioneer TS-WX206A. The idea is that it won't take up my space in the boot - i don't want thundering head shaking bass, just the bottom end to be catered for nicely. Failing that, does anyone know of any premade enclosures for the CLK that I could fit a custom sub / amp into? Thanks for the advice!
