LUV bass

Yeah, the doubling up is probably a good idea. Is there a specific formula for a 4th order, or just plug stuff into WinISD, that's what I've been doing, but the frequency response always seems pretty peaky.

Thanks man! Yeah, drove the luv through high school, def. a chick magnet. I'm in college now, and the truck is back home, but I really want to get this underway over the summer.

There we go

So apparently I'm a noob and don't know how to post pictures.

Here's the truck and a sketch of a possible box design. My question is, does the space between the subs count as part of the port? So like if i plug this into WinISD, do I add the length and area of the common center chamber to the port tuning? I'm just not sure how to tune a box like this. The box is for 4 15's (i'm thinking DD 515b's) The dimensions for the back of the truck are 73" long, 15 1/2" high, 52" across with 39 1/2" between the wheel wells. If anybody has feedback on the box, or a better idea, I'd appreciate it.

Hey everybody, I just joined the forum today, but have been looking at it for a while now. Does anybody have feedback on the Digital Designs 500 series 15 (515b)? Or suggestions for comparable subwoofers? Any advice would really be appreciated!
