Hi guys,

wondering if you could shed some incite.

I have a 2003 MB c230 kompressor coupe with a premium BOSE fiber optic OEM stereo system. The head unit is BECKER and it has a 6-disc cd changer in the glove box. The bass is a little weak as it has a small 4 x 6" subwoofer in the side of the rear trunk. It's not bad but my brother wants to give me his vintage Kicker stillwater mid's and tweeters. I'm wondering if you think they would sound better than the BOSE? or just keep the BOSE.

Any incite into how i can get more bass into this fiber optic system without changing the head unit would be really appreciated.

thanks

You generally can't make piecemeal changes to a OEM Bose based system, so upgrades are pretty much impossible. Bose factory systems have proprietary equalization for the specific vehicle, and also sometimes have unusual speaker impedances. The real question is do you want to replace the entire factory system?

I was able to change the head unit in my 2004 Audi S4 Bose system using an aftermarket adapter, but it's analog (RCA) based. The required adapter was quite expensive as it has to turn the Audi factory wiring bus into conventional deck wiring, and I suspect MB will require something similar. I made the change to add Bluetooth and NAV functionality, not for sound quality. If I want to take the next step in sound quality, it will mean changing all speakers and the Bose factory amp.

The optical fiber is probably just a signal connection between the head and the sub amp. Same as a fiber optic toslink cable but with out the toslink connectors.

The fiber only runs between the head unit and amp.
A speaker swap is possible noting impedance but much more looks like some wiring is required.

That's what i thought. It's all or nothing. The designers at MB and BOSE probably spent months figuring out the best sound for this vehicle putting in new speakers may change the dynamics.

If I can only get i little more bass I think that's all i need. Any one add a sub box to their OEM system? and how did you do that, please.

thanks

Your only option to add a sub box is to try and pull a high level signal off the factory Bose sub amp. The problem with this approach is that signal probably won't extend down to 20 Hz, as the factory sub is not designed to play that low. Also that signal will be equalized for Bose's choice of crappy woofer. There are expensive solutions that can re-equalize the signal, but that won't help the missing low bass frequencies.

I took a meter reading to the BOSE subbox and got a weird ohm reading of 2ohms or something like that...I have a ported wedge type small box with two 8" vintage DENON 4ohm DCS 802W's woofers and a vintage 100w Rockford Fosgate Punch amp, can i not run a separate power direct to the battery and then disconnect the BOSE sub box and tap into the sub box wires somehow?

Did you read my last post? I pointed out exactly what is wrong with trying to use the signal off the Bose sub amp.

Sure there are, but one guy quoted me $750 and one guy $3000. As soon as you drive in with a Mercedes, cha ching... I have the parts, and I thought this is something i can DIY.

If it was me and I wanted to upgrade, I would consider the "Mercedes-AMG C 63 S"... now that would be an upgrade!!!
