         I recently bought 2 12" Kicker L7's (2-ohm models).  I'm now looking for an amp that matches up nice with the speakers.  I'm looking at the Orion 250G5 which is an 800x2 amp stable to 1 ohm.  Am I right in thinking that if I hook one DVC sub up to each channel, and connect the coils in parallel ( positive to positive and negative to negative), then the amp will run at 1 ohm putting 400 watts (maybe more) to each sub?

      Am I right about this, also anyone have any other suggestions for amps and how to wire them to get my stuff running at 1 ohm?

Yeah that will work. If it is one ohm stable per channel. The dual 2 ohms subs will run one ohm each if you run them in parallel.

The Orion HCCA 250G5 is a competition amp rated at 200 watts X 2 into 1-ohm per channel, or 400 watts X 1 into 2 ohms.  Since this is the same thing, I recomend you connect your subs in series-parallel and bridge the amp into the 2-ohm load.  This will ensure both subs get the exact same signal since the amp will operate in mono which helps prevent cancellation effects.  Connect them like this:

       I was under the impression that the Orion put out 800 W.  If what you're sayin is true, then I'm looking for more RMS power.  I'd like about 200 W to each coil.  I'm also willin to put out upto about $600.  Can u recommend a different amp, or maybe two smaller amps (one for each sub)?

Yes, 400 watts is about the max RMS power for a S12L7 unless you use a relatively high subsonic filter of 25Hz.  Since I think that's entirely too limiting for the performance of these drivers, 400W is a good target.

So, you need approximately 800 watts mono stable at 2 ohms for under $600?  Take a look at the Hifonics ZEUS BRUTUS BX1500D, a JBL BP1200.1, MTX THUNDER 801D, a PHEONIX GOLD OCTANE R 15.0:1, or a PLANET AUDIO APD.

   Would a Soundstream VGA 1600.2 get me there if bridged and wired as you posted above?

That amp requires a 4-ohm load when bridged, which you cannot produce with two DVC 2-ohm speakers.

PPI PCX 1500 is a 1000 watt at 2-ohm amp.  It's a bit past your $600 target, but a good choice.  If it was me, I'd go for an APD as my first choice and JBL second.
