How abot the JOY RIDE HU by clarion? Now theres a fawkin HU! If you got like $3500 to drop on a HU, thats what I would get! Its got a pentium 3 CPU, GPS (for navigation), 3X4" LCD (might be a plasma display, not sure) for a face -this is also a touch face-and it can play dvd's and display pictures- It has a 100GB hard drive- more than my computer has right now! and you can install anything on it that is on a cd-rom! Now thats a bad ass HU! Its like a frigin laptop that looks like a HU..... Actualy it IS a laptop that looks like a HU! You could probably hook that thing up to your ECU and tune it, the JOY RIDE system runs windows... isnt hondata a windows based program?

As far as amps go there are alot of great amps out there. I chose to use a JL amp and I think they are ONE of the best amps out there because of there versitility. You can run the amp on 11-14.5V and it will put out 500 watts, you can run it from 1.5-4.0 OHMS and it will put out 500 watts! None of this 500@4Ohms 250@2Ohms 125@1Ohm crap, you GET 500 RMS all day long as long as your in the 1.5-4OHM area! Now that fawkin impresive! Oh yea, MOST 500 watt RMS amps will only put out a 707 watt peak, this amp puts out a 920 watt peak
