ok...so here is what I have installed and I can't seem to get things tuned right...I have an ED 9.4 installed with channels A/B connected to a set of Polk Momo 5250 components in the front the C/D channels are bridged to a JL 12" sub in the rear...I am running an Alpone 9856 HU. I can't seem to get the HU and the amp all tuned to sound nice...I'm not looking to get any car shaking bass, just some nice low end from the rear and nice sweet highs and mids from the front...any audiophiles out there any help would be appreciated...i really wanna start enjoying all this new gear....thanks

Its not perfect but its safe and works well.

I read the thread earlier, but it's doesn't seem to take in the polk crossover settings or the settings on the amp itself...i'm looking for something a little more specific than the turn the HU up all the way and adjust the gain...oh well...i guess that is just how it is done then...thanks
