Cerwin Vega 12D4

The sub could be shorted or the wire connections of the sub could be shorted, or there could be an internal problem with the amplifier such as a shorted output stage or failure of some other component(s)

Passive woofers are hooked up to the output of a sub amp.
Active woofers are hooked up to the sub out of a receiver. They have the amp built in.

the box is 5.75 cubic feet

basically its length x width x depth in feet

I found www.parts-express.com to be good resource. I also found the amp on SearsParts.com

Just get a 12" sub box enclosure for an audio store near you or make a custom box, a larger box supposedly gives you more bass yet at the cost of boot space. I have a type R sub and the box is only as big as it needs to be for the sub to fit and it gives amazing bass.

do you want the box ported or unported (holes or no holes) if you don't got a lot of room than you dont want a ported box. keep in mind the box has to have the correct amount of cubic air space or you could seize your sub... if you're building it make sure you use OSB board (oriented strand board) or MDF board(medium density fiber) your sub needs .7cubic feet of air space in an unported box

Same thing is happening to my Cerwin Vega 18" sub. Can't find solution at all. Guess I will have to buy a new sub.

i need to know what the box dementions are for a 15 inch cerwin-vega subwoofer v max 1000 w peak power?

are you gong to use this in your house or car?? any type of enclosed box air tight.. will do if your useing it in your house a box you can face the cone faceing down would be good with a port in the front about 3in would be good. be sure to purchase a cover for the speaker you dont want the cone smashed .you dont want any air leaks .. you can go to any car stero shop and have a box built.if you have good wood working skills build it your self 1/2 in partical board works ..you can also get the port tube at like a raido shack.and speaker port for conections weather it be rca or speaker wire type
do not nail your box wood glue is best

I bought my VE-28s and it did exactly that crackled, cerwin replaced part in amp but few months later problem persisted. they then replaced entire amp assembly and its been fine. i really push it to and its been fine. to test it, unplug the connection from amp/ reciever and see if it persists. if so its the sub, if not its the amp/ reciever. dont dump it, these subs really crank and can put out some deep loud bass.
