4 level four 15s in a sealed box?

[Nu_South_Audio]

I built an avalanche about 4 years ago using 4 mean machine 15s. Its a sealed blowthru a gets pretty loud on 3k. Now the customer wants to double the power and change subs. How would the level 4s perform in a sealed box. Its never been on the meter but he's definitely louder then i am with his current setup and i hit a 146.7 burp and a 144.? On music. Does anybody have any experience with any of the dc subs in sealed boxes?

The level 4 15s will perform great in a sealed box. Look up mr ps jeep before it was parted out. He had 12 level 4 15s in a sealed tunnel.

i built this last weekend.

lvl 4 18s and it was sealed cause the customer had to have sealed. it sounded great to be honest...it caught me off guard and i was really surprised as to how hard it hit. plus the crispness it was great.

the subs are good sq subs even in the right ported box so in a sealed they are awesome. i would suggest it...

i hope this helps

Any pics of the back of the box? How big was it ? I just made a box and throu it back there. I love the sealed off look. How much does something custom like that cost? do you ship?

Sorry but it was for skyhigh since he posted the pics.Don't mean to thread jack just thought that a picture of the back would show better how everything fitted with those 18's

No problem. But those avalanches are super easy. U don't have to cut nothing just build a box to fit in the bed and a trim ring. That bed cover leaks but as long as u throw some glass on the box and the back of the trim piece your good
