tune box to most resonant frequency of car so you can put more power into that 1 frequency.

Double up drivers.... 1 8ohm speaker off an amp having 90db/w/m. If you hook up 2 of these speakers in parallel you should now have 96db with 1 w/m/into 4ohm load.

Or add another amp channel with the exact speaker for a +6db increase.

Remember you need to double area driven so 1 speaker 8ohm 90db, 2 speakers in parallel 4ohm load 96db, 4 speakers in parallel 2ohm load 102db. But most amps run cooler and live longer at 8ohm. they live less long at 4 ohm and even less at 2 ohm. Assuming that the amplifier perfectly doubles its power into half load.

Yes I know they have a crap load of transistors, but current through means heat. The more current, the faster it will die.
