DSP Equalizer question

Recommended Posts


I have looked through the 'search' areas and can not find an answer, so I thought I'd try asking you guys.

I have a 1999 C2 Coupe with OEM CDR-220 Radio - OEM AMP (located under the hood in front of the Battery area) - OEM 6 Disc CD Player.

I came across a OEM DSP Equalizer and want to install it in place of the 'Cubby' hole, just above the heated seat switch plate.

My questions are..........

1. Is there a cable that connects the DSP to the Stereo that I can buy.....or part number?

2. Does the cable go from the DSP to the Radio or does it go to the AMP?

3. Does anyone out there have this cable they would like to sell me?

4. If there is no cable, can someone tell me which 'pin' (inside the female connection) is for making the face plate lights come on?

I have enclosed a picture of the front and rear of the DSP in hope of helping you understand what I'm trying to ask.

Thanks for any help in this matter,


Patrick Ford

Probably not worth the trouble (IMHO). Doesn't do much - and most people I know have removed them.


Loren, thanks for your input...................But for me this unit will look better than a hole (cubby). I really don't care if it works I just think it will look better. Thus.......maybe someone has this 'cable' that will make it work; as I still plan on putting it in my Porsche. Thanks also for the wire diagram photo. as always, you are the man :-)

For your information, or for any future reference, the 6 pin (2x3) connector behind the DSP Conroller, is part of the main harness of the car and it goes to the AMP (M680 DSP, that amp for your info WON'T WORK IF YOU DON'T HAVE THE DSP CONTROLLER PLUGGED IN), you can't buy it separatly. If you'r rewiring it and need a connector, you can use the computer motherboard connector like theses one.. you can take two 3-pin connector side by side to give you the 2x3 pin layout.. It fit perfectly behind the DSP, but I suggest you tu put some glue or something to avoid it of getting loose.. You can esaily find them for free at any Geek Friend's home or computer part recygling shop .. :)

Don't hesitate if you have other questions.. :)
