maybe try replacing one of the 4" with a 6". then try upsizing both.
more powerful amps
better battery

In StreetB, you can't have two batteries.

the car is Civic Coupe [Smile] i saw that big box is lowering the freaquency.. sub don't like lower than 50hz freq. on 2 Oxigen audio.. still searching good box size.
yeasterday i made a 2.4cu.f box, with port of 60inch2, and 20 inch long. and it made 144+db at 49hz (legal)
and 146.3db with opened driver doors.. then played some basstests on 100+v in amps output and damaged the coil.. now i will try shorter port..

For spl and your frequency I'd step the box up to 2.5-3cf with a single 6" aeroport or if you can fit two that would be even better. 1.5cf is to small for a 15" even for spl with your frequency.

yah for sure shorten the ports. Should be almost half the length then they where with the small box.
