Skar audio Zvx 12 dual enclosure

Recommended Posts

I've been trying to figure out the right specs for two Zvx 12v2's. Their website recommends 3 cubic feet per sub 6 cubic feet total after displacements but I've heard anything from 4 cubic feet to 7.5 cubic feet. Any pointers on what I should run?

I'm not sure exactly, but going with factory recommendations didn't exactly work out for a single enclosure. Everything was tuned right and the sub was bottoming out (running rms power) at a volume well below clipping on my head unit. So far both shops and friends that I've had look at it have all said that the problem is the box is too big. The volume was 3.8 cubic feet taking into account the .65 cubic foot port displacement and the .15 woofer displacement and tuned to 34hz like their website recommended.

Not just the enclosure, but most likely amplifier power. Running recommend ???

Yes Recommended is 1500 rms a and 3000 max and that's what I'm pushing. The weird part is I've watched 3000+ watts rms run through those subs in a different build and they took it no problem.

u can run 3k on this sub no porblem box rise will up sub impedance so u will get around 2k or less on 3k amp depends on enclosure. clamp those subwoofers and see for yourself.

@mfdoom7That's what I don't understand. I was pushing 1500 and having issues but other people can run 3k and have no problem. I took it back to skar and they said everything is fine with the sub so that really narrows it down to enclosure size. But I built it to their specifications so something isn't adding up.

@mfdoom7 It was tuned with a dd1 so I'd assume it's not clipping. But I was running a skar rp2000 at 1 ohm and I had the gains set damn near all the way down. And now I'm running it at 4 so I'm Pushing around 800 watts out of it. I hooked up my friends skar rp1500 at 1 ohm, tuned it with the dd1 and ran into the same bottoming out issue even at rms.
