Hello. This problem has been happening for awhile. When i play games or watch movies, after a while my sub woofer starts to make popping sounds and other little noises. When it does the popping, the light blinks between Red and Green. I have it hooked up to my receiver via a RCA cable I had laying around. Is it because I am using those cables? I am looking for a direction to start going into to resolve this . Thank you.

you might be pushing the sub to hard. i have the same sub and no issues at all. try turning down the gain volume.

Trying a set of component cables that are shielded. Hoping that was the issue.

well the cables worked for a few hours and then it started doing the popping and rattling again. I have the volume on the sub itself a little over half. Surely that's not over working it is it?

Perhaps a bad amp that starts acting up once it gets warm. Its not the cable or the volume or it would act up all the time.

No, Mr. Bond. I expect you to die!

It usually starts doing it a half hour or hour after I start watching a movie or playing something.

The popping could be due to a failing electrolytic capacitor (which can fail with heat and time - some capacitors may not be made as well as others). One of my subwoofers gradually got worse in that the intervals between the pops grew shorter and shorter. I replaced the amp with a Parts Express 500w BASH plate amp.
