I have to agree with the possibility that your wired out of phase between two or more subs.

pics and vids tomorrow and i will also take the subs out and check to make sure they are wire in phase right. hell you guys might be right with 8 voicecoils to wire up i could have messed one or two up

double check your amps and wiring? head unit settings?

easy answer to this, just take a drill battery and "pop" all the subs to check polarity, as long as they are going the same you should be good

i remember saying before 2.5cubes is small, but if they reccommend it i cant argue since ive never used them

Or any battery.....

I'd be willing to be some of the coils are out of phase as well.

 

[bvr_j_0969 10+ year member]

[hoodkid 10+ year member]

im pretty sure they are all in phase, 2 ohms and they should be getting 325 rms per sub (rated at 300 rms)

Heres a thought, your expectations are too high.
