The issue a floating ground that causes the hum you are talking about. What are you connecting it to that causes the hum?

hi,
You have to check the RCA cable to the sub woofer. The RCA cabe have two connections inside it, one is for gain and the other is for ground sheild. If the ground sheild is broken then there will be hum from the sub woofer and it will increase if you touch the ground (rear metal pannel is connected to the ground). Replace the cable and check it again.
ok

it sounds like a bad sub woofer amplifer, as the unit heats up the capacitors start to leak and the amp will try to shut down. it would depend on how hard you are driving it, (heavy bass versus light bass) that would cause it to fail sooner than later. You need to replace the internal amp

I also had the same problem, I bought final scratch used with 2 ground loop isolators, even with those I still had the buzz. After buying the
3-to-2 prong 110 volt plug everything is perfect

I got mine and homedepot

I'm having an issue with my Velo DLS5000R. I pulled the amplifier,and inside the plate, where the power cord goes in, is a small 8amp glass-tube-type fuse. You might try checking for one on your sub.

First I would sugest you contact the place you purchased it, they may be able to test and repair if needed.

The other option is to contact Velodyne directly for service.

Already answered for DPS-12 in 2011 which suggests a fuse where the power enters, However, your manual mentions no fuse, but 'protection circuitry'. If there is a fuse, it will be inside and on a circuit board. All fuses have the rating on the end cap of glass fuses and on the side of ceramic fuses, which as also colour coded. https://velodyneacoustics.com/pdf/vx-11/VX-11Manual.pdf

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.
