2 amps, 2 subs, what can i do

hi there. new here.

i have two mtx x300dp under my seats they are 300 rms @ 2 ohms and 200 rms @ 2 ohms.

i have two mtx mxs 1004 in the hatch. 4 ohm svc 400 rms 800 peak

i just got the second amp

before i had them bridged to 2 ohms. i was told by a guy that each sub received 300 rms. im not sure if that is true. i was under the impression that the max rms for that ohm level was split by the two subs so 150 rms to each? was i wrong?

if so, that would mean that im now running 100 rms less and consuming more power.

how can i (if posible) wire the amps and subs so both amps are bridged and maximizing power? or did i just spend 150 bucks to say i have to amps?

Each speaker was getting 150 watts before.  Now each speaker will be getting 200 watts. 

sweet thanks. btw, your not an idiot. i am :)

idears about the wiring situation?
