HPAS Amplifier Help

[911Joel]

So I installed the Porshce high performance audio sytem this weekend. It was a little more work than expected.

The one problem I am having is the amp does not appear to be working.

The hpas amp has 4 indicator lights, one of these being power and it is not lit.

Ive verified power is in the wires all the way to the amp. The fuse for radio options (d9) is ok.

Any ideas where else I should look?

Check the ground path. If you have a good known power supply and the remote trigger is working then confirm the ground.

Ground seems ok. I just reversed testlight where I hooked the one end to postive at the battery and then poked the ground wire near the amp and it lit up fine.

How would I check the remote trigger?

Well I found the error of my ways. I should have done a little more research prior to installing :)

Anyways I have DSP M680 and this will only work as M490. So I going to remove the DSP.

I was assuming I just may have to switch a few leads on the amp cable but looking over the schematic Im not quite sure how to go about it. I guess one of the first things I need to figure out was if the +12 from the stereo is not installed in lieu of the DSP +12. Or is it just a matter of removing the DSP for this to work.

Any help/advice?

Heres the chart:

For the record you can use an existing M680 connection in a M490 amp.

When I first removed the cable I had removed a wire from the pin. When I reseeded all wiring both amps worked perfect.

It was interesing to hear with the DSP amp. If it had more power to drive the speakers I think it would have sounded really good. I hooked up the HPAS amp which I think is like 720 Amps. Sound was incredible.

Much improved over the DSP system.
