My subs start to play at the same time I turn on the Emergency lights, will this ground loop get rid of that problem?

This is to get rid of fuzz, pops and background noise caused by a bad ground loop. If your subs turn on when you turn and play music when your emergency lights come on you must have wired something wrong and grounded something to the same connection as your emergency lights.

Radio shack also sells ground loop.isolators or you can build your own from a 1:1 transformer this should also fix the hum as well.

I cannot confirm that the LED lights are the cause of the interference, but I can confirm that my AM/FM radio started to have issues with regulating the volume after installing the LED lights. Now the volume starts at a normal decibel and then quickly gets very quiet, with an inability to turn it very loud.

Sounds like somehow the power is not getting to the pole amp. the lower indoor unit is the power supply. If i had the problem i would short the outside end of the coax. If the wire is good then the power supply will turn itself off automatically. If not the coax is cut somewhere. It is possible to plug the amp in backwards.

Have you ruled out a ground loop as the source of hum? http://www.youtube.com/watch?v=4YM1iwC6vhg http://en.wikipedia.org/wiki/Ground_loop_%28electricity%29

Yes. It's a 4 channel amp so you will have to bridge 2 of them. If you are running subs on another amp the cut out issues could be from lack of power from your battery/alt. Try adding a compacitor..

The speakers are standard wiring so they shouldn't be an issue with your prewiring. As for the sub, nothing appeared to be different, however, could not say for sure since I don't know your prewire configuration. As a side note, I recommend a Harmon Kardon reciever so the sub can be turned off when the system is turned off. We currently have a pioneer reciever and we have to manually shut off the reciever.

When I first tried using my receiver's "subwoofer out" connection, the sub wouldn't turn on automatically. The reason, I determined, was that I didn't have the subwoofer selected in the receiver's menu. Once I made sure that the sub was, indeed, being fed a signal, it has been working flawlessly. I hope this helps.

Are both subs powered, if so switch the inputs to see if the other works if not you have a bad RCA cord. Hope this helps you.

his will not take out a bad grounding situation!! power conditioners do not do that. what your hearing is 60hz hum, meaning that the circuit in your system has started a loop, also if its audio, make sure to use only balance connections or isolation transformers! try using one outlet for your gear and make sure nothing else is sharing the same circuit

I would think that APC might prevent it, as it controls the amount of amperage/electricity going to your sub. On the other hand if you sub has any internal issues it might blow the fuse as well. Did any other items get damaged or blown at the same time, if not then I would think your APC is ok and your sub is the issue.. Call APC 1-800 tech advice and pose the ?

I've experience the same problem when bolting the amplifier down to a vehicle. From what I can figure it's a grounding issue. In my particular its other equipment installed in the vehicle that is not grounded properly.

the same thing has been happening to me. I think it may have something to do with the slight spark and pop that occured when I attempted to connect my speaker wire while the unit was on.

The auto on/off works just fine on both of my Dayton SUB-1200 subs. Once a low frequency signal is sent through the LFE into the sub it turns on. They do seems to turn back off a little too soon but its not too bad. I would have to say it seems like a couple minutes of no audio they turn off.

Salim; the red light goes on when the subwoofer starts working, should always be lighted red when you use the system. My advise is to consult with a DT (Toll Free: (800) 228-7148) Service associate; he will guide you on what to do.

I am not an electrician so what I would do is Google it. Check out this site... http://www.epanorama.net/documents/groundloop/why_grounding.html

Check all powers and grounds connection then double check and make sure your speakers are wired to the right resistance
