15s require alot of cubic feet.. HUGE box!! and may have clearance issues in ur trunk.. i would fire the subs and port in same direction.. this yields higher SPL.. and facing forwards reduces the shitty trunk rattle.. my last comp i hit 145.9db at the windshield wit windows up.. and u could barely hear it outside

dude i can help u with a system.. If I was you, I would run 2 12s in a custom ported box firing towards the cabin.. realize that your amp's RMS should match or be higher than your subs combined RMS. and Higher wattage amps require juice.. we're talkin 0/1gauge wire, extra batts, alternator. I only run 3000watts rms and needed 2 extra batts, optima yellowtop up front, ALOT of wire, an alternator.. i suggest 2 Audioque or Digital Designs dvc 4ohm subs and 2000 watts or so.. the AQ 2200D is a beast and would be fuckin insane on 2 SDC2.5s in about 4-5 cubes tuned at 35ish hertz.. and Knukonceptz 0ga wiring and Kinetic hc2400 batt or 2 Deka Intimidators
