Ok, as of right now judgement day didn't turn out so well. I have the amp rack in and all pwr/grnd/rmt/rca/Ai-Net wires run and all the amps and PXA-H100 are getting a good 12v w/ the car on, but engine off. Problem is I'm not getting any signal I know this because when I went to set gain on amps I only get milivolts at 75% volume out of the speaker terminals from my test tone CD, so I plugged in a speaker and there is nothing, not even tuner.

So it seems I need to troubleshoot the signal system, so I have 9886 giving signal to H100 through the Ai-Net. There are no RCAs connected to the 9886. The 9886 sees the H100 because the expanded Imprint options appear. The H100 is giving signal to the amps through some Monster Home Theatre RCA (didn't have time to make my own yet). This seems pretty simple, so I'm assuming there is a setting or dip switch somewhere that is not correct. I left the dips on the 9886 at Norm instead of the Ext AP (or whatever it is).

Any ideas here?

K, so the no signal was due to dip switches on HU, but now my tweeters are acting weird.

When I play the 1khz tone they can't be heard until the volume gets about 50%, then at 75% one of them starts making a faint pulsing sound while still playing the tone, then it pops (clipping I guess).

Mids are good and loud below 50%. Tried the tweets on the mids amp and exact same thing, so it isn't amp.

Put in the IASCA test disk and the guys voice is not at all correct. Sounds like he is far away and it is also hard to understand through the tweets. When you turn up the volume, a white noise type sound increases at a greater rate than the voices. It sounds as if it thinks it is really loud!

Thoughts?

Ok, reset the deck this morning and still no good. If I just run the tweets they sound awful, the USCA disk has the guy talking and he is hard to hear and I still have a slight pulsing sound coming out of one speaker.

Currently all my amps have filters off and set to full range and my HU has all settings off (bass boost, EQ, etc.). I'm basically thinking the H100 is a crossover and that it is sending the correct freq to the tweets by default. This could be a mistake on my part.

The tweets go to the 'rear' RCA on the H100 correct? This is what the manual says, but seems counter-intuitive (would think 'front').

I think I'm going to resort to some local guys for help since there are so many variables that could be wrong (tweets blown, sys not tuned, misc noise, etc) that I'm lost.

Ok, so the 'pulsing' sound I was getting out of one of my tweets has been isolated to the Ai-Net replacement cable I bought from eBay (haven't been using the factory cable at all since it is only about 6 feet:

So do I get this and use it to extend the factory:
