2011 - C-300 Sport 4MATIC - Palladium Silver
If anyone can help it would be appreciated.

I just bought this powered sub and plan to place it in the rear shelf.

Boss Bass1400

these are my car specs - 2011 - C300 SPORT without HK premium sound - just the stock Audio20 and stock speakers.

I'm not planning a DIY project but would like to know what to expect on this install as I search for a professional shop.

From what I've read so far on this thread.. here's what I have:

1) pull power directly from battery and run it through car to the trunk
2) confused on where to draw the sound from? Anyone know for sure if the Audio20 has an easy way to install a powered subwoofer to it like the one I mentioned above or do I need to cut into rear speakers?

I purchased a Boss KIT-2 Complete 8 Gauge Amplifier Installation Kit - Does anyone know besides tools what else I will need for this project?

Any help here is greatly appreciated. I want to be able to let the installer know exactly how I want this installed without getting a quick and lousy install.

both these should be resolved by adding a high level converter from what i have read, it hooks up to the wires in the back of the deck, and it outputs rya cables and has everything u would need for an aftermarket sub/amp install,

Is it possible to replace the stock sub? Where is it? I've got one from my old car and I would love to just replace the one one. I've also got the base, stock stereo system.

(sorry in advance, I know ABSOLUTELY NOTHING when it comes to stereos)

Tap the remote wire with an add a fuse. I will have to look and see what fuse I tapped but it is in the rear set of fuses. Just make sure you pick one that one gives power when the car is turned on. I need to install my setup in my 2010 so I will be doing it next weekend. I can post pics then.



Hope that helps.

Working on this right now... Like others, I am trying to keep all but the speaker wires coming from the trunk. Anyone have a pic or more specific details on which pos wire to use from the fuse box in the trunk... And is there a fuse back there that would be perfect for the remote wire?

Here is a pic of my rear fuse box - there are 2 red wires (one is a little bigger than the other)

Can one of these red wires be used as a POS for the amp? And if so, how would you suggest doing it? - splicing the wire and attaching another wire to it sounds harder (and maybe unsafe) than to just run a wire straight from the battery... And is it ok to unplug the wire to splice it - I guess one should disconnect the power wire from the battery?

Any suggestions or tips would be appreciated

I know this post is pretty old but I thought I would post this up for users that are looking for this answer more recently. I had been looking for information on how to remove the rear seats on my C300 and found little information when it came to detailed pictures or videos so I made my own:

W204 Rear Seat Removal - YouTube.com
W204 Subwoofer and Amp Install - YouTube.com
W204 Sub After Install Performance - YouTube.com

As far as the remote wire goes, I tapped into the 15 amp fuse in position 76. I have been using it for a while now with no issues.

Thank you...

Followed these directions... great writeup. I did add a much bigger gauge wire from the battery. . Tapped my remote wire from #76 on the fuseblock in the rear. Ground to the groundset behind the rear fuse block.

I'd only add that pulling up those plastic pieces on the floor to gain access to the wire trays are a beotch...

Oh yea, instead of pulling out the wiring harnesses from the doors, I just tapped into the wires from the bundle of wires leading up to them .

I added a Bazooka 8" sub coupled with a Bazooka Branded EL1500 sub amplifier.

Remember to use the right crimping tool and to use heatshrink tubing!

Fronts/Rears are next...

Regarding REMOTE, use a control ligt on the fuses in the rear SAM module, one fuseblock is activated on ignition position 1 and another fuse block is activated with ignition pos 2
Go to your dealer to get the correct fuse holder for that block, then you can just solder the contact carrier to your remote cable and hook it up to the SAM and insert desired fuse.

My friend has done smething like this similar i think, he doesn't run power to the battery (front) but he does it all from the rear. Do you know what that is?

Vic - If you have the time, could you take a picture or describe exactly where to tap into the power that goes to the SAM module in the trunk and where to connect to a good ground?

I have a 2008 C300 4Matic and will be installing Infinity speakers in the doors as described in other threads. Your thread with pictures on installing the HK speakers in the front doors is invaluable, BTW.

I must say I don't care for the looks of the Bazooka. I'd prefer a self-powered sub under the shelf, like the Boss installed by AcapulcoGold, but without running remote wires to the front.

I'm actually running a double insulated 14 gauge wire (instead of the recommended 16 gauge) for the power wire and 16 gauge wire for the speakers wires (high level inputs) for my 100W amplified bazooka. According to Bazooka, that will suffice.

Taking off all the interior pieces (especially the B Pillar covers) took very little time by the way.
It's been a while since you posted this excellent DIY with pictures but was wondering whether you could help with two questions I have. I intend to install a small Kenwood sub in the passenger footwell, where the netting is. It will fit as it is very thin and small and maybe 75 watts. Looking at your pictures, is it possible to run a coat hanger wire through the grommet in the footwell and pull the power wire through the engine compartment without removing the battery?

Also, since I am going to take the speaker level wires from the HU, are the colors the same as the left right +and - wires at the B pillar clips you have photographed?

Any suggestions are welcome.

One more thing. Since I need a 12 volt remote, I was planning to tap into the 12 volt supply to the outlet in the glove compartment. Any way to tap into that without dismantling the glovebox? Thanks in advance.
