Deck screws huh? I think I'll probably just use the classic drywall screws...hopefully I can find some with a hex or torx type head. I'll be mounting the subs face up too, so I'm too worried about them poping out, just is a lot of power. I'm thinking 1" MDF, but would like to stick with 3/4" MDF. These subs are definitly BEEF!

Atleast do the face 1" and use proper box bracing

I was thinking of going a common chamber with bracing or just separting the chambers and no extra bracing.

I'm running my 2 opti1535ds in a 7.5 cube wall with 123sq in of port tuned to 36-37 Hz. On 2 bb2400.1s strapped at 1.2 ohms.

All 4 coils measure at 1.1-1.2 ohms

I'm thinking about shrinking port area to lower tuning and gain a little port velocity and even shrinking airspace to obtain a more musical sound.

On a side note my subs get stinky and my amps get hot quickly full tilt,note gain was set with a DD-1 My best score so far are 148.0 DB bassboxing and 148.1 DB burping sealed at 43hz

If the desired sound is not obtained the I'm considering swapping them out for some SA15s or SSA subs.
