Well, I bought blown hdc315 for $50, having it reconed to 10" and gonna run it for while next off american bass 120.1. Its going to be in a scion xb, back seat is out now because still have my obsidian 18s in til I get this built. Should I do slot port or aero, daily use, maybe a comp or 2 if they are close by. Around 1.5 cubes @38hz? Any suggestions
