I have a quick question, i have a sx900x2, and 3 10in L7's.i understand that series/parallel put me at a 2.67 ohm load. and parallel/series puts me at 6 ohm. whats going to be better for my set up, if ran at 2.67 what will happen.

You amp is stable at 2 ohm in stero mode and 4 ohm bridged
You safest way to wire them is with a 6 ohm load bridged
but I feel that the amp would be safe at 1.33 ohm per channel, with 3 4 ohm coils per channel of the amp.
I would highly reccomend the first option as it is the only safe manafacturer recomended way of wiring it, but I believe you would be fine with the second option as the coils on the L7's actual measurment is about 4.4 ohm and with impedance rise of your enclosure you should be fine
If you decide to try the second method make sure that you amp does not produce excess heat at any time

So this will make the amp overheat a little faster, i ask this because its going to be behind plexi. it will have fans moving are threw the compartment but dont know if thats going to be enough.
