In preparation for my real subwoofer (JBL GTO 1014) in a sealed box, powered by a Kenwood KAC-7204 500w x1 @ 4 OHMS with an MTX Re-Q for the line level output and bass restoration, I built a box to seal up the rear deck. This will tighten up the Mid-Bass and protect the 6x9's from the pounding the JBL would give them from below.

3" H on the Rear of the box
2" H on thr Front of the box
1" x 1" - 45 degree cut for the drop to 2"
38" Wide (If I remember correctly)

I used black Plasti-Dip to paint the box and "L" brackets to mount to the rear deck. I put 1/2 thick door foam rubber insulation to seal most of the gaps between the deck and box.

Did you put any dynamat (or similar) product in the box? Or would it not be needed having them in that small a space?

The box is so shallow, I did not put anything in there. I will probably Dynomat the top of the deck at some point. The rattles may appear after the sub starts pounding the trunk. I don't think I'd seal the 6x9's unless you are adding a real sub. The bass seems to be tighter, but may not play quite as low, I'm not really sure... It sounds great, though, less sloppy with heavy bass. The JBL will provide the super lows soon

Completed the Woofer Addition

I used an MTX Re-Q, tapped into the 6x9's for high level input, had a 4 gauge power wire run from the battery, installed my Kenwood KAC-7204 and Polk Dxi 10" 4 ohm woofer in a sealed .9 cu/ft box. I'm really pleased with how it sounds now.
