DSP amplfier


Recommended Posts

I have an '01 Boxster S with the M490 sound option (ie CDR220 H/U, HAES 4x40W amp) and I have recently added OEM rear speakers. I also have purchased an HAES 6x40W DSP amplifier and DSP faceplate that fits into the center stack. My question is this, if I cut the alignment keys off of the connector and plug my system into the new amp will it work and do I need to use the center stack DSP faceplate as well. Thanking all you stereo guys in advance

I misunderstood your post in the other thread - sorry.

Anyhow, the M680 amp should work as long as you also hookup the DSP controller which necessitates an extra wiring harness be run from the amp back thru the firewall to the DSP controller in the center console. That's more than a fair amount of work to do for the results.....

When upgrading amps from the 4x40 to 6x40 (or just replacing) you need to make sure you get an amp w/ the same architecture as the existing... M490 or M680 (DSP).

Good Luck :)

Any idea what the part # for the extra wiring harness would be?

Sorry, no I do not know the p/n or if it's even available separately :unsure: . I'm not 100% certain it would be a separate harness to the DSP from the amp either. It's likely tied in w/ the main harness which runs from the amp to the h/u and then a portion truncates off to the DSP amplifier. You may want to call Jeff Clark at Sunset Porsche or someone at Suncoast Imports as they should surely know the answer. Good luck :)
