Subwoofer locations without losing the spare tire

Better as in night and day difference to an average user or better as in only noticeable in a competition?

I like the upfire box cause it's smaller, lighter and looks like a better visual fit to me since it doesn't extend higher than the side panels. Overall goals for the car are much more performance oriented so I'm more concerned with having something that sounds better than stock, but it doesn't need to win any awards for SPL or SQ. Hence the desire for a pre-made box vs a custom built system.

Ideally I'd find one that was half this size and held only one 8" sub and an amp If I go with just one sub I'll use a JL Audio 8W7, if two I'll go with something comparable but not quite so pricey so feel pretty comfortable with 8s over bigger subs.

Thanks for the tips guys
