Its time for me to get some JLs but I dont know what will fit in my car. Two 12"s or two 10"s?? What kind of box does everyone have? I want the 12W3s soooo bad but im worried the top of the box will hit the bose speakers and not fit....any ideas??

Just hit 122,000 today

 

I have two JL 12" W0s and they fit beneath the bose speakers

 

Any 12" box will fit under the speakers. The trunks in our cars are pretty big. Most JL's use small sealed enclosures so you will have plenty of room. As far as getting W-3's I would pay the extra money for W-6's. I personally dont like JL's much but the W-6's are pretty good. Deffinitely better subs out there for the money.
