is this box in a trunk car?
if so, turn the box around so the port is forward and take the 2 subs closet to the port and fire them forward as well
so you have 2 subs firing up and 2 forward

Wait till deadly gets back to you. You need to seal it off the car and figure out if you wanna burp loud or play music that you listen to daily. You could build a burp box and daily the sealed one. I would ge a bit more power as well. There's a on of heavy hitting amps for sale here too. Then figure out if you want to seriously compete or if it's just for fun.

Not a bad idea Less. Yes, it's in a trunk. Derek has a box that would allow him to fire all 4 subs and port into the cab but your way he can reuse the box he has. Wouldn't be bad.

Maybe try Less' idea first, get tested, then test with dereks box and see which one you gain more from. It's the only way to tell for sure. Honestly, for daily driving and LARGE SPL, you need either LOTS OF POWER, or 2 boxes. One for comps and the other for daily.

I hear that a audio shop in Chatham will have a meter soon...

You also have A LOT more power than him... Not to mention it was WAY to low to be successful in SPL comps. It was good daily, but your forward firing boxes kill the old subs up one. ... and sounds better doing it. lol
