dosent matter you can cut the whole bigger anywaysNo.
OP, does the box already have holes cut and everything? If not, you could upgrade to 18(s). Why'd you sell the subs with a box on the way?
just cut the holes bigger if you do a 18 or 21. throw another layer on top, plug the 2nd hole if youre not using it, doneI had the subs in another (smaller ) box. They were in my 92 Suburban but before I could switch things around the transmission went out in the Suburban. I kept everything but after hearing my brother beg for two years I caved and as fate would have it I acquired another Suburban 3 months later. And yes the holes are cut already.
No prob bro I knew you were kidding lol. I'd love to hear a Jackhammer in person. I'm still looking at subs but I think this might be a good one to start with:Dayton Audio TIT400C-4 15" Titanic Mk III Subwoofer 4 Ohm 295-420**** man, so many people hating on the Jackhammer... it's a joke man
