I am in the market for an in-dash eq/preamp for my car stereo system. I am using the stock deck, then the signal goes to 2 amps that power the highs in the front and rear. The second amp powers my sub. This is what I am looking for by priority:

1. Sub level control
2. 3+ bands of eq adjustable q if possible
3. Aux input (to plug in my MP3 player in my car)
4. 24db crossover


The closest I have gotten has been the Audiocontrol Three.1. It has everything I want minus the aux input. Anyone got any other suggestions for me?
