You'd be surprised at what I've found.
It's important to test *each* output and in the passband it will be playing as not all of the outputs will clip at the same output nor the same frequency. Even on "higher end" units like the P99RS I've found this to be the case. I attribute this to the part tolerances used in manufacturing.
My HU clips at 51.4% of max volume. That is an actual figure... Knowing this allows me to maximize use of my DSP.

Why would you pull back on the DSP outputs and not the amp outputs? 2 reasons I can see not to:
1 signal to noise ratio, trim those amps back
2 you only have so many bits in the digital domain, use them all.
I've seen one instance to have a reason to have amp inputs just pinned, literally pinned.. To keep some jackwad from turning them up after the DSP is locked.

Well I am going to try and make this mini speaker to set the gains. I don't have Radioshack in Canada but will try and see if I can find a similar item. I found all the instructions on the rockford fosgate site.....

Lets just hope I can find a mini speaker like the one from RS!
Great find! I'm just going to start linking to that lol. The only thing different that I saw from the "kit" that mark uses is he put his voltage divider into a small enclosure with RCA inputs/outputs on it instead of putting the resistors inline on the harness. Both end up at the same goal though.
