Alright so i've got two sets of Clif Designs QX6500 componets and a KX650.4. I've got a full car's worth of dynamat extreme on the way to do the whole car. I've got a US Amps XT2000D waiting for the sub. The car is gonna be a 1999 Diamante as long as transaction goes as planned. I've been set on a single 15 for awhile but after lookin in the trunk i may have room for an 18. Any suggestions, maybe another set up???

I haven't seen too many 18s in trunks because the box is humongous. Before building, I'd make sure that it will not only fit but you can get the box into the car as well. It would suck wasting all of that MDF and time. If you are hell bent on putting an 18, you can build it in the trunk.

Your car will probably ride with its ass draggin'

Ya i was set on a 15 but after seeing the size of the trunk i'm very tempted to try to pop an 18 in there. I'll measure it up and see if i got room. Maybe two 15's??? Damn it gets harder to choose when it gets down to it.

i personally would go the 18 just because not that many people have 18's.

Get another 15. That would rock. Never had a 18 before but I listened to 2 brahma 15 and it shakes my balls out of my pants.
