Static sound builds up in the sub pops, then no sound comes from it. The sound comes back once I reconnect the power source and fiddle with the power plug. The problem then repeats.

its real simple. your under powered.

your W6s RMS at 500 watts EACH and your sending em 250RMS (half what they need)
The 'pop' your hearing is the failure to supply enough power to draw the cone back in time and collides with the next wave of sound.

prove it?
drive a single W6 with your 500/1 bridged.
i'll bet your pop goes away.

long term, get another 500/1 or jump up to a 1000/1v2.

I also HIGHLY recommend JL's in-line audio cleaner. If i recall it was like 60 bucks but waaaay worth it. makes sure that theres no distortion in the source input to your amp(s), which...keeps your subs from trying to reproduce transients and delivers only clear signal to your subs void of all clipping signals. Its an active electronic compoent.


PS: if you are pushing 12W6's, i had the same setup once...I had W3s connected to my 500/1 and upgraded to the W6s...had the same issue your describing, and then got the 1000/1. happy ending.

Hi

reinstall the sound driver

thank you

You should NOT have anything that draws a lot of power drawing AC from the back of a receiver.

Try turning it off with a different source selected. Or disable the speakers because you

two things to try

1. try using another usb port ( preferably one on the back of the pc)
2. switch out usb cable with another
   

larryagross,
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.

You may have a faulty check valve in the fuel pump which should hold a static pressure of at least 1 psi to the injector.Excessive cranking can be caused by this due to the fact the fuel pressure needs to build back up in order for the injector to deliver fuel.A proper diagnostic step would be installing fuel pressure gauge and verifying any static pressure held after the engine has turned off.If the fuel pressure gauge drops immediatley to zero,this might be your source of the problem.Another source could be improper temp sensor output or crank/cam sensors therefore an E/C parameter check with a scanner could prove usefull.

Sounds like a conection problem. disconect all the cables clean the connectors with something like deoxit or any terminal cleaner. reconnect all cables making sure to make the correct conections. If you do not have a signal ground between your sub and amp you should consider it if it is a powered sub the signal ground can go to the preamp or whatever your driving it with.

good luck

looks like you need to check the SOURCE of where the signal is coming it could be that your CD car stereo SUB opt. is turn off , check the menu of SOURCE and switch to SUB on , hope this helpful

1. How old are you phone lines in the house?  Check the "main" terminal connections.  Clean and reconnect.  (Make note how the wires are connected).

2. The power transformers for the phones maybe you trouble also. Unplug all except the main unit.   Check each transfer one at a time. Do you have static?  One or more may be your problem.  Replace the bad ones if needed.

I could either be the sub or the main unit. The main unit actually sends a signal to the sub to turn it on so if that circuit is bad in the main unit the sub is never going to come on. I've also seen bad cables (You'd be amazed at how stubborn people can be when din connectors don't cooperate).
