I'm considering to buy C 200K, but I need to find out whether the car is possible to be installed with sound systems (i.e. amps, subs, etc) because as far as I know it's a fully electronic and fibre optics everywhere in the car electric systems. And also to change the tape deck as well.<br>
<br>
Please, need advice!<br>
<br>
Thanks

I did. To be very exact, a first stage of<br> audio upgrade. As my car is equiped with<br> COMAND, i have no way of replacing the<br> head unit; however, stuck with COMAND,<br> one center-mounted CD player and six-cd<br> changer in the glove box might be not that<br> bad. As a former minidisc fan, i've just<br> bought cd burner and a pile of blank CDRs,<br> transferring all of my MDs into CDRs. Mercedes<br> CD player reads them very well. However, it<br> is unable to read CD-RWs as my sony did without<br> any problems. Back to the audio.<br> As an owner of 320T-Model (estate) i was told that<br> Bose was not available at the time of purchase<br> in the estate version. But on the other hand<br> i heard some bad rumours about new release of<br> Bose, so again it might be not bad to save some<br> money on the expensive audio system that just<br> dont work.<br> Factory speakers (six) sound very lousy and<br> when you hear that, you are pretty sure what<br> is the material they made speakers of - a paper.<br> Entire system sounds just like a paper.<br> No depth, low bass, distorted mids and very,<br> very annoying, attenuated range of 200-500Hz.<br> High frequencies sound pretty good due to<br> tweeters mounted in the corners of front<br> doors, but i feel that high fill could be a bit<br> better. Rear is also lacking highs.<br> But what you can expect of cheap speakers<br> with paper membranes and baskets made of a...<br> plastic! In fact speaker basket is a part of<br> element that mounts entire speaker to the door<br> assembly. This looks very custom and it is not<br> to be easily replaced. So i've bought a set<br> of four identical speakers (Helix; this is a<br> brand of german car-audio maker Brax; perhaps<br> not very old and famous but they were awarded<br> several times on various car audio contests).<br> Speakers were 16.5cm (6 and 1/2 inch), rated<br> 80W peak power - as far as i remember. There<br> were also tweeters and crossovers supplied.<br> I've removed factory 'speakers', and, of course,<br> destroying them, i've made sort of 'adapters'<br> off them, screwing on the new speakers on<br> the plastic elements. I've also mounted<br> x-overs somewhere inside doors, replaced front<br> tweeters with supplied ones. I;ve also cut<br> appoporiate holes in the rear door (WATCH THE<br> SIDE AIRBAG, my car has rear ones), putting<br> two additional tweeters there. Hint: to remove<br> door trim, take a closer look to the inside<br> door handle; it splits into two parts, if<br> you remove outer one, there will be two torx<br> nuts,another one is below the 'SRS AIRBAG' plastic<br> cover, you can pry it off with a screwdriver<br> but do it gently. Rest of the door trim holds<br> on bare clips, just use some moderate force<br> to pull it off.<br> <br> System doesn't sound cheap anymore, thanks to<br> far better speakers. Of course, you cannot<br> get very low bass from 6 1/2 inch spkr, so<br> my next step will be to install a sub<br> somewhere in the rear cargo space. As<br> you cannot connect amp to the factory<br> system (the only way to interface with it<br> is to connect speaker outputs to the<br> amp input, which is not the best way) i<br> decided to modify my COMAND unit, friend<br> of mine installed 4 cinch pre-outs into<br> my head unit. I already have approporiate<br> amp so i'm going to use it to drive<br> 2 rear & 2 front channels, and use<br> separate amp to power the sub. We will<br> see how it does. email me with any<br> q's, i think that i'm somewhat deep into<br> internals of new C right now, and still<br> learning.<br>

I did! after going to 3 and four new places<br> what they needced to do is go analog out from the speaker wires (at the connections on the actual speaker) its the only way, every other way is almost impossible, it cost me a pretty penny though im up to $2,000 in the sound system.. but my sounds great

Install fibre amps...

What I am thinking of doing is<br> 1) replace all speakers as Michael has done above<br> 2) instead of using speaker level outputs into an amp (which compromises sound) or modifying the head unit to add 'preamp' outputs, I was leaning towards the purchase of a Becker Audio fiber optic amp (the Energy 350 is 60Wx4). This will plug right into the fiber ring in the car and the fiber is essentially a preamp-quality connection.<br> 3) next is to figure out how to add a subwoofer - I believe Horst Becker mentioned that you can connect TWO amps into the fiber ring so the second bridged amp can be used to drive a sub box.<br> 4) the only other solution is to rip out everything and install your own head unit, amp, and speakers, but you will lose the and steering wheel controls. I don't have COMMAND.<br> John
