I'm sorry, i cannot aid you in this case, but you can consider to double power of the sub for to gain +3dB.
And for SPL you can use a class D amp and get high power.

Duplicate thread here:

The OP apparently has an amp in the 1kW range and 12" woofers.

He wants to achieve the highest SPL that he possibly can for a local dB drag type contest. Fidelity is of no concern in these situations, only to register the highest number on the SPL meter. Most likely using a pulsed signal, not steady-state. Exciting a mode for huge one-note resonance is key to winning.

For one note with the highest gain, a bandpass enclosure may be the best (but not a simple) option.
Anyone who purchased the repair tutorial, email me (babin_perry@yahoo.com) if you want to download the latest version.

Yes, I saw that crazy...
If it's raw SPL, I'd be much concerned in what's behind the speaker, the body of the car etc. Imagine how many losses from the holes and the pressure
( To OP: you must have problems, seriously. Calm down and search for quartets/quintets with violins, violas, cellos, pianos, harpsicord, harps, flutes etc in gardens, verandas )
