w7 or l7 solobaric ?

 

Any specific reason why you're chosing between just these two subs? There are a ton of great sub companies online that have killer subs for better pricing. If you're set on those two, its going to come down to what you have for space, money, and what name you want showing (since both are good pieces). Just make sure you've got it bolted down and as out of sight as possible; these cars are way too easy targets for thieves.

 

because i could trade my l7s for w7s trust me i would rather have to 18 inch fi btl or some re xxx subs but i dont feel like getting a lone for a sound system lol

 

If you can "trade" one for the other why not try both in your car and see which one you like better? As it was said before, both are good subs and it's going to come down to personal preference.

 

Between the two, it seems that the W7 is more the SQ-oriented sub, while the L7 seems to be a bit more on the SPL-side. A lot of it will come down to what kind of music you like, but try like previously mentioned; make a quick and dirty adapter and try them both out in your current setup. It may not be the most ideal test, but it could at least give you an idea what to expect.
