Solution For Amp Turn-off Noise

[james33440 10+ year member]

Okay ya'll, I have installed my new setup in the sig, and I have no complaints in terms of output. However, I do have an annoying noise with the 1200d amp (not the 3002).

The noise occurs when the deck is powered off, deck is on and the car is turned off, when the volume is turned down to 0, and when the cd changes tracks.

I have checked the RCA's, swapped RCA's between the 1200d and the 3002, I even rewired the remote to the car's ignition and I even tried the battery wire with a switch. Oh, and I have a relay already to turn on my amps. Yes, I even tried it without the relay. Also, I swapped grounds between the two amps as well.

Nothing seems to work. BTW, I have no hissing noise or alternator whine whatsoever.

So, I came to the conclusion that the amp is the culprit and I imagine that the 1200d doesn't have a muting turn-off feature. I don't know if that's true or not. Seems to be though.

Now, would a relay that turns off the amps be a solution? How about this one, Stinger SPSOFF?

Please give me some advice. This does get irritating... there's nothing like 140+db when your amps turn off! //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif

Anyone? This is really annoying. I guess I will buy the Stinger SPSOFF and hopefully it will work. If it still does the noise, any ideas?

Could you possibly try another Hu and see if the thump goes away?.

Just get the pop stopper and be done with it...

try adding a relay to your remote wire... boosting voltage... see if it works...

^ I already have the relay to boost voltage. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif it does it without the other amp with and without the relay on as well....

I am going to check the grounds again though just to make sure once I get home before ordering that Stinger item.....
