hmmm i don't really know of any prefab boxes for the coupe that can fit 2 12"s.
As far as i know, you can get them for either 1 or 2 10's or a single 12". You can always go custom. may have to. what JL's are they?

definitely no prefab will be big enough for 2 12w3's to perform at their best. recommended airspace is like 1 1/4 cubes per sub so you need about 3 cu/ ft gross for the pair to have about that after displacement, bracing, etc

If you want to fit 2 12s, you're going to need to have a custom box built. There are prefab boxes for a single 12.

Just throwing this out there, would it be possible to use the prefab 2 10" enclosure and make the cutout diameter larger for the 12?

Or you can get a single 12, on ethat fits in the corner and buy two of those.

Lastly, custom box as everyone else mentioned.

i think the prefabs for 2 10" are like .8 cubes per side gross, so he would only see like .65 per sub after displacement.

Just go for a custom enclosure, the thin subs will be ok but you might as well stick with what you have and get better output, or sell one and get a single 12" enclosure prefab from Zenclosures

top ones = not enough airspace for your subs

bottom ones might be ok just kinda look weird and i prefer not having the sub firing up in these cars unless you dynamat the crap out of the trunk lid. you want the sub to be firing off as rigid of surface as possible
