your gonna have a loud system there, not a fan of twin subs but nice nether the less.

just posted on your other thread bout this mate!
DONT CRANK THEM UP LIKE THIS!!!!
you could blow ur amp cos ur running them at too low an impedance.
ok you said you have two spare terminals on each sub....
on each sub......
move your negative connection to the negative connection that is free and leave the positive one where it is. then link your two free terminals (one should be positive, the other negative).
this will work fine and give you the 2ohm load resistance which you need
