has it ever worked, if so did you ever use it in the cold because in the cold it is possible for the wiring inside the speaker to crack and break

Sounds like you blew the speaker! The amp is sensing the voice coil is connecting to the speakers magnet or iron core and is going into a safe mode. It is possible to blow the coil even when the sub has a built in amp.

First make sure that you have the gains properly set ans not all set to their maximums. Second, disconnect signal to the sub then unplug the power for a few minutes. Third, plug the sub into a source of power on a different circuit using a surge protector.

Does the speaker make any popping at the time it powers up? If so you have a amp problem. If there is no sound produced, connect it back the the system using a different signal cable. Does the speaker now pop again when sound is produced. If so the speaker has failed. Contact a Velodyne repair facility.

Have you selected the appropriate input type? (e.g. Optical, HDMI?)

Some receivers (like my Onkyo 606) support HDMI passthrough, but will not decode audio signals from HDMI. Making it a pretty useless port!

Do you get sound when you select FM Tuner on the Pioneer?

It sounds like you may have ripped the passive (the rubber material around the speaker that stretches when the speaker hits. If the passive is not ripped then it may be picking up static, or it could be blown. You can purchase a noise filter fairly cheap and try that.

You need to remove 12 outer screws, then remove the amp it might be held in with gasket.
