ok so i have 2 12 inch mtx 9500's in the trunk of my 97 grand prix coupe and i have 2 rockford fosgate t1500 amps hooked up to them and they are up almost all the way so that there isnt any distortion comming from the subs and im hitting at about 120 decibles and i was wondering if anyone knows how i can get them to hit harder? they are in a slot ported box. would they hit harder in a seeled box or what should i do?
