Looking to build a new system, and figured I'd ask you guys. Which one would be the more practical way to go?

i would do an 18" if you have the space

2 15's would require more space than a single 18" wouldn't it? plus i'd think the 2 15's would be louder. but require more power for 2 subs as opposed to 1.

2 15's is by no means im-practical...and probably got an edge on 1 18"

Yeah, I've got a '95 Grand Cherokee, so space in the back really isn't too much of a problem.

Edit: You all bring a good point...I never thought that the two 15's would be taking up more space. Also, how big of a box would I need for the 18 to reach optimum performance? I really didn't plan on taking up my entire cargo space as I do a lot of travelling.

Can anyone tell me how large the box needs to be for an 18", and will it most likely take up my entire rear area?
