This is what my amp setup info advise me to do, maybe it will help you out:

1. Set LPF to 100-125

2. Set Subsonic to 30-35

4. Set the gain on the amp to min(all the way to the left)

5. Install the remote gain and turn 1/2 way up (the midpoint on the dial)

6. All EQ settings and bass controls on the HU to O

7. Turn HU volume to 3/4 and insert CD (perferbably a recorded CD and not an mp3 At this time you will have no output because the gain on the amp is turned down)

8. Slowly turn the gain on the amp until it starts to sound bad and then turn it down below that notch.

I've modified it a bit...good luck.

dmm tuning.

Download and burn a 50hz sine wave...

do the math for your voltage ... sqrt(watt(rms)*ohms)=voltage

play the sine wave, and turn the gain till your dmm reads the voltage

if your going to do dmm tuning...MAKE SURE it's a good DMM ideally with true RMS, also make sure your in AC voltage for measurement, if your a little worried about the quality of your DMM just back off a tad when you get your desired voltage.

get a dd1.. The 75% volume thing really holds your system back.
