Thanks for posting the links. I will try to paruse them over the next couple of days. I'm definitely not looking to build my own amps at this time... but the setup you're working on really does appeal to the techno-geek in me, Shankenstein.

The Mini-DSP intrigues me, though I admit that currently the Rockfort Fosgate 3-Sixty-3 is high on my list right now as well and would be the "safer" choice that still gives you plenty of options to play with. My big question about the Mini DSP is what sort of adaptation is necessary for the mobile audio solution where it's going to be subject to significant vibration and other harsh environment factors.

I'm currently working out what sub driver to buy... I think I've pretty much settled on the JL Audio 10W3v3 but trying to decide whether I'm going to get it in 4ohm or 2ohm versions. In the past I've always used dual 4 ohm voice coils wired in parallel so they showed a 2 ohm load. I'm leaning towards the 2 ohm for the reason that it will push a bit more thump for the same power, but that will be amp dependent.

Still haven't finalized my amp options either. I did want to go with one 5 channel amp rather than two separate amps... I was hoping to find something with enough power to safely handle the sub I've chosen, plus still feed 75W or more into the components once they're installed... though if I'm running them without the passive crossovers, do I need as much power going into them to make them sound good. I've been trying to find some individual specs on the power handling to get a line on how to handle the tweeters. Another option that I was interested in was Speaker Level Inputs, so that I could hook it up and get the bass channel done without having to pick up some kind of line output converter... but I'm favoring the Alpine PDX-V9 which would need a LOC to hook up the bass before I get the processor.

If anyone's got some good input on which impedance to go with on the sub driver, I'd like to make the purchase by the end of the week when I get paid. Amp suggestions will also be helpful since I might jump on the right one once I make up my mind.
