Recently upgraded from Kicker CVR12's to JL Audio 12w3v3-2 subs and..

It seems like the kickers might have actually sounded better. I think its gotta be the box I am using though. The box I am running is a Subzone Dual 12" Vented Subwoofer Box its got 1.4cu ft of air space. The jls recommend 1.75 for a ported enclosure I asked the guy at crutchfield before I ordered them and he said it wouldnt matter. I have read rave reviews about the 3w's and from what im hearing I think the kickers were better. Can someone tell me if its my box or if those subs are just over rated? I am running them off a Memphis mcd-1100 wired in parallel for 1ohm. The jls are SVC. The kickers were dual voice coil. If you wanna see a pic of the box I am running heres a link. SubZone HD Series Enclosure Any input would be greatly appreciated. Another thing is I have let them break in for id say a good 20 hours.

You should build an enclosure specifically to fit your subs and vehicle.

Prefab box = crap. Make yer nice subs sound like crap too.

Upgrade again to something that isnt over rated and way over priced... but yes it probably the box Id have one built if your gunna stick with those subs

Would i be better off going with a sealed enclose? Also, what means prefab?

Depends on the type bass you want... And prefab means it was mass manufactured box that wasnt built for your particular sub

Where would i go to get a box specifically built for my car/subs?

Well my box was built by a member on here (the one in the sig) and I am very happy with it

You should ask for a box design, and build it yourself or have someone build it. The difference would probably be huge.

I would think the difference from your enclosure to a custom built for your application enclosure would be pretty big. You can tell a builder to do a bit more "generic" air space and tuning so you can have the ability to upgrade and not have a need to purchase another enclosure.

what are you looking out of your subs? were you looking for loudness or sound quality?

 

[rbtrucking 10+ year member]

Id say im more looking for sound quality.

 

[rbtrucking 10+ year member]

For best sound quality i would probably want a sealed enlosure. Am i right?

Yes

I know you said prefab boxes are crap but i was looking at the recommendations in the manual for these subs and i found a box, the sound ordnance bass bunker dual 12 inch sealed box has basically dead on specs. Would that be a bad choice?
