I purchased a Crossfire BMF W15D Semi-Cheap off a friend, and thought I'd try a Home or Car 15" DIY project. With that being said, does anyone have an idea where I might find how big an enclosure I'll need for this sub? Sealed or ported? (For the Home DIY People...)Do you think a Velodyne Amplifier VLF Series (unsure of wattage & Velodyne website isn't helpful) would be enough to drive at least so I could enjoy it? P.S. I do have 2 Amps if you think I could do one on each Voice Coil(hmmm?) Unsure.
