if the RF amp has high level inputs, take a feed off of the front speakers, and use the x-over in the amp.
Otherwise you can get a high to low level converter from any car audio shop.
Once that's done, you could probably ditch the 4X6 woofer system, as the Denon's will perform much better.

Actually, the front speakers are not likely to have any bass frequencies in them, they will be going through a high pass crossover in the Bose OEM amp. The best signal source is the factory sub speaker signal, and I have already explained why this less than ideal. If the OP just wants some loud, nasty, one note, mid-bass thump, then connecting the aftermarket amp using the factory bass speaker leads as high level inputs will produce sound, but it won't be the same as connecting to an aftermarket deck that provides un-molested sound. Although I don't know this car specifically, I did work in the car audio business for a number of years, so I have some experience with this subject.

Clearly an aftermarket deck is the way to go, but the OP has expressed not wanting to go this route.

Taking a feed off the existing subwoofer signal - doing so before the existing amp would yield the best results, agreed?

You already know that those Denon's in a proper box will be much better than that 4X6 already in the car.

Doubt the OP wants one-note bass, otherwise he wouldn't be here. I also worked in the industry for a number of years, and have built a few SQ vehicles. ;)

The only thing I know about the factory Mercedes/Bose systems from that era is, that in the higher end models (E, S, SL, etc...) they were purposely designed to prevent owners from screwing around with them and in some cases, even being wired into the alarm and other control systems of the car.

Ask a Mercedes specialist before attempting anything; it might just not be economically feasible and you may just have to put everything back the way it was before just to get the car running again!

but my concern is a) does his amp have line level in and b) will the signal to the sub which has already been amplified have too much gain for the aftermarket amp?

if he purchases a line level to rca box will this still be an issue / concern?

How would this be accomplished exactly? The factory Bose deck in my Audi doesn't have a dedicated low level sub signal, and it is pre-equalized leaving the deck.

It doesn't matter how capable a speaker is if the signal is compromised or missing entirely.

That would be why I told him at the outset that you either live with the Bose OEM system as is, or you dump the entire thing.

One Alpine type r sub at 1000 watts and 2 type s 6.5 coaxial at 100 watts each, with proper power wiring, power doubling amps, and a pioneer head unit, will blow that stock system away.

I bought a 1999 MB CLK320 In 2004 & within few weeks ditched the stereo & speakers for something I could truly enjoy. Had it done at Kromer which is gone. The car stereo still sounds great. Today I would go to Number One Sound on College St.

:!: If you are hoping to avoid costly and troublesome
upgrades. I can recommend without reservation that you
can stay within the Mercedes- Bose family of audio parts .
You can unplug your C230 sub and replace it with a flat
dual ported one from an ML 1999-2002. They are located
under the drivers seat. Bose uses the same plug and play
two channel wiring config . The improvement in base will
astonish you. This sub is easily fitted discretely most
anywhere in your Mercedes . Very likely under the drivers
seat. You will have no trouble obtaining one from an auto
wrecker that has some ML's on hand . Removal is easy.
Hope this helps .

Thank you to all, and thank you OKIMPORT for your idea of using another BOSE subwoofer from another MB model. Very ingenious. Perhaps even from another make will work, such as Cadillac, Nissan etc...I will look into that option... There are tons on Ebay and the wreckers as you mentioned. :wink:

From what i've learned so far about my particular BOSE stock OEM system is that I have (1) set tweeters up front, (1) center speaker on the dash, (1) set of full range in the front of door, (1) set of full range in the rear of door and (1) subwoofer in the trunk. The BOSE amp has 6 channels of amplification and are usually 22 watts per channel, one channel is for the BOSE subwoofer. The BOSE system also has a thing called "AUDIOPILOT" sensing technology microphone built into the EQ. The BOSE system is designed to make its speaker components sound the best it can with its propriety EQ volume sensing system. This system limits bass output at higher volumes to protect its stock speakers from damaging, and even if you replaced the stock speakers with a different brand of speakers, you will not get everything you paid for out of the new pair and not all BOSE systems have volume sensing EQ built in. The BOSE speakers all incorporate a very low ohm impedance resistance, common BOSE speakers are 2ohm, 1 ohm and ½ an ohm. BOSE does this so it can extract as much power as possible from its amplifiers, the lower the speaker impedance an amp sees on its outputs the more power it can extract from its amplifier. This low speaker impedance can cause problems when trying to replace a BOSE speaker with a common 4 ohm speaker normally found at any retailer. since the common standard speaker is a 4 ohm model (not including subwoofers) it will extract significantly less power from the BOSE amp making the new aftermarket speakers have a drop off in volume output and not usable.

There are very few options when replacing a BOSE speaker, you can either scour eBay looking for another used BOSE speaker with the same impedance (there are many different types of speakers for the BOSE system, finding an exact match can be daunting though) or you can purchase the only known compatible speakers to work with BOSE speakers. The infinity kappa series. The other option is to remove absolutely everything and replace all, but many of MB systems tie into the engine immobilizer, steering wheel functions and alarm, making it a costly nightmare to upgrade.

If i don't find some substitute BOSE subwoofer donors as per OKIMPORT's suggestion, I still believe there is a way to tie into the wiring at some point with an amp, subs, and a 2-channel line level controller with remote turn on.

Interesting discovery i made while surfing: Many big companies have dropped BOSE.

Mercedes Benz also WAS using Bose exclusively: now is offering Bose as midline and Harman Kardon as top of the Line choice.
Toyota/Lexus is now with Mark Levinson and Harman
Acura was with Bose: now with ELS Surround [Elliot Schiener Surround]
Audi was using Bose only: now, has B&O as their top of the line option: Bose is midline.
BMW also WAS also using Bose exclusively: now is offering bose as midline and Harman Kardon as top of the Line choice.
Ford/Lincoln switched out from Bose... they use THX II certified systems and Sony.
Chrysler uses Kicker
Rolls Royce uses : Lexicon [division of Harman int.] and Bespoke Audio Systems
Jaguar: uses B&W
Ferrari used Bose in the past and now uses JBL as top of the Line choice.
Hyundai uses Infinity.
KIA uses Infinity.
Nissan continues to use Bose
