DSP amp upgrade


Recommended Posts

In case you have the Navi/info system installed and the 6 speaker soundpack but no DSP you can add a DSP amp fairly easy. If you "only" got the 6 speaker sound pack it can also be done but is fairly more tricky.(ask if you need help)

Actually the biggest thing is to run 2 wires from the amp to the info system.

The 2 wires needs to go:

1. From the small black 18 pol connector pin 1 (DSP-GND) on the amp to the blue 26 pol connector pin 6 on the info / navi system.

2. From the small black 18 pol connector pin 17 (DSP-DATA) on the amp to the blue 26 pol connector pin 14 on the info / navi system.

The wiring route can be done thru the same way as the CD wires go (if you have that) or you can use the spare ones.

In order for the big blue connector to fit the DSP amp you need to cut away the taps on the brown DSP connector on the amp. (see pics).

List of items you need.

1. The DSP amp. M680

2. 1 piece of 1 meter 2 pol wire

3. 1 piece of connector pol (000 079 010) cut that in half (used on the info/navi system)

4. 1 piece of connector pol (000 079 009) cut that in half (used on the amp)

Install the 2 wires and hopla....you now have DSP available on your screen. There is no doubt that you can hear the improved sound. :jump:

Good luck, and fell free to ask if any questions

Nope. With PCM1 you only need a DSP amp. and some wiring to make it work, the control unit is build into the PCM system. If you don´t have PCM1 you will need the control modul.

The sound is much better with the DSP amp compared to the regular M490 amp.

With the CDR-220 you will need a DSP amp and the control unit M680-662. I am not sure if the amp and control unit is build in together...Tool Pants will know.

Anyway, if not build together, you will have to run quite a lot of wires. especially if you don´t have 6 speakers and thereby then the M490 amp (soundpacket) But it can be done.

To add PCM1 and then DSP would also be possible......but then there is a lot of wiring to be done. Another guy on Renntech is working on adding PCM1.
