Oct 28, 2012  Mercedes-Benz C-Class W204 Subwoofer and Amp Install. This video is the step-by-step process that I followed to run the wires in preparation of installing a sub and amp in a 2009 Mercedes C300.

Hey guys, I'm going to add a sub that I had from my previous car into my 06 c230 this weekend so of course MBWorld would be my first stop. I searched for a few days on this and found a lot of threads, but the portion for running the power to the battery is what is eluding me. I did see one install where the poster recommended removing the plate underneath the glove box, where I can find four holes that go through the side wall. My only problem is that I looked at the hole and there's now way 4 gauge wiring is fitting through there.

I'm running a single 10' JL W3v3-4 and I really don't feel comfortable running 8 gauge wiring to that. I also saw another post where the poster ran the power to the stock amp under the seat and tapped that for power, but that doesn't sound too safe either. My question is, to those who have added subs with 4 gauge wiring. What's the safest and easiest way to get the 4 gauge wiring through the firewall.

Did you build that tray yourself?yes of course. The sub fires up thru the existing sub mounting holes. The tray is hung via 4 bolts installed from the top. Heluva job to remove the rear deck to do this. Right now I am running a 600 watt Pioneer PRS sub amp driving the DLS 10 inch sub. A 2x300 watt PRS amp for the DLS Nobelium mids, and 4x 75 watts for the DLS Tweets tweets and rears.

Awesome stuff. The C Class is so very quiet inside and the doors dont rattle at all I also opened up the audio unit and solderd RCA outs to the pc board right after the DSP/DAC outputs. I know this thread is more than a year old, but let me see if I can save everyone a little time. To install a sub amp in the rear you do not need to run a wire from the battery through the fire wall under the carpet to the trunk. There is no commercial 12 volt amp that can consume the current supplied by an AWG 4 wire.
