The first thing to do is unplug it, then pull the sub out of the cabinet, then pull the amp out of the cabinet. If you can take out the amp w/o taking out the sub, great. If there are any exposed printed circuit boards, look for dust buildup. Sounds like you've got alot of static energy built up in the internal electronics. If you have to disassemble the casing to get to the circuitry, do so, just do it carefully. Look at the boards. If there's alot of dust, get some printed circuit board cleaner.(pcb) cleaner found at Radio Shack. Then spray off the boards and the subs volume control as well as the crossover control. This will Not hurt any electronics.Re-assemble and test. If you still have noise: Take a careful look at the input side of the amps circuits and traces, if you have a magnafying glass it helps. What your looking for is a bad solder joint. You will see all the little dimples on the boards from soldering at factory. When you look at the solder point, look for a circular ring generally midpoint on the solder or right at board level. This can take some time, however, it's free and it's more than likely the problem. To fix a cold solder joint you need a fine point solder gun, just touch the point that is bad and it will re-seal, then test. Plug n Play. Hopefully it's just dust and you don't have bad solder joints. Velodyne makes an awesome product!, very rarely do I see problems with them. If you need some more help with this, post a comment and we can dig further. Hope this helps

Go to the Velodyne web site and check the service center locations.

They may have one in your area.

It sounds like the amp may be the problem. That may be all you need to send.

Best bet, Contact Velodyne.

Crackling from bass combo when I hit low notes


I'm afraid it sounds as though the speaker has been overloaded. The replacement for this will, unfortunately, be a new driver (the speaker unit itself).

Not that it would help.

Is the white noise present in the absence of an input connection, free-floating?

The amps in both of them sound like they

Fuzzy sound when instrument being played


The 1/4" output on your bass needs to be resoldered in 1 or more places. It's very common.

Very low ouput from subwoofer preout


The problem was that some subwoofers (inluding my velodyne model) cannot process the LFE signals through the line level inputs on its amps, so the other way to run your subwoofer is to run the front left and right speaker outputs from your receiver to the speaker-level inputs on your sub, and then plug your front and left speakers into the soeaker level outputs on the sub. you have to set the onkyo receiver to "Subwoofer: No". that way the LFE signals are sent through the front speaker channels and you will get the same BASS output as if using the line-level input. O So yes it does require a bit more speaker cable, but it works fine now.
