Jbell- yeah I did completely check it out I'm just not too worried about keeping everything 12v- and the 24v/48v 600W class D amp I mentioned looks to be higher quality, higher output power, more versatile (2ohm bridgeable), probably a lot lighter weight, and about the same cost- just without the built in crossover. I could use cheap components to step down to 12v to run all my other 12v stuff like mixer + wireless + el wire + etc.
My guess: that philips amp has a switching power supply that steps up the voltage to 40+/40- volts on the rails. I don't trust the efficiency of car amps, even class D. This is just speculation, but an amp asking for 24-48v supply probably means the power goes straight from the leads of the battery to the rails of the amp, no in-amp switching or voltage conversion necessary- that seems ideal for an amp putting out some power!
Looking at some efficiency calculations, it seems that the faital pro's will have the same 120dB max output with only 2 drivers at just 30W per driver (60W total) compared to the NS6 which is 4 drivers at 50W (200W total). I'm thinking now I will just use the faitals and make an MTTM enclosure which will be smaller and provide slightly better battery life.

The Peavey speakers have fine mids, I don't think a three way system will gain you much output and complicate the project.
If I built another one I would use four of these tweeters
and try to bump up to a pair of 12" or 15" neo drivers and have them fire 360`.
Thanks for posting a pic! Come to LA and ride with us!!
Once again my whole reason for this project is to get the lowest & loudest bass possible out of the smallest / lightest setup. I know that low frequencies outside are possible, my eon 518s sound great outdoors- granted, they are 18's. However won't devoting the 4 x 10" peaveys to just the 150hz and below range free them up from the mid range and allow them to get louder at lower frequencies? Originally I did want to keep it simple with a 2 way system but having dedicated lows makes a lot of sense to me- relieving the mids and highs from the lows to get the most out of the lows.
Ok I am seriously honing this setup in, thank you guys so much for the help and criticisms.Drivers
