So, I'm finally buying my Obsidian 15 d4 tommorrow, and I just want to get my first system right the first time. I'm wiring it at 2 ohms at 600 watts to a audiopipe aspm1300. SQ=SPL. Thats the criteria. I was thinking of doing 3.4cubes at 32hz. I just want input on what the box should be. And i will be pointing the sub into my car, i don't want to deal with vibrations from my trunk
