My trunk big enough for DC XL 15"?

[KeepItLow91]

I recently saw a thread where someone said for a DC XL 15" you want close to 15 inches of port per foot and 50-80in² of port area. And seeing how I'm only giving it 1200 watts, I wanted the box to be around 4.30 Cu. Ft. to make it more efficient. I'm wanting to tune around 32hz but I can't find a way to get the recommended port and desired box size out of the dimensions I have. Hopefully this won't turn into a back-seat system

DC XL 15" with a DC 1200 watt amp. Max Dimensions - 17" tall, 33" Wide, 21" Deep

You should go with the lvl 4 on that power. IMO 3.5 in big enough

I would go with the Level 4 with the Level 5 upgrade unless you plan to upgrade to a bigger amp.
