Subs randomly burp

[93 saturn sl2 10+ year member]

This just started doing it yesterday. I'll be listening to a song and I'll be bumping and my subs will just burp another note for a second and then continue to play the song.

Sometimes it will do it a couple times when I drive and other times it wont do it at all.

Any ideas of what it could be?

See if it does it with your sound all the way down.

mine does it too, also have a pioneer hu, does it with the volume off also, replaced rca's, no help. buying new hu soon. the worst thing about mine is sometimes when I turn it on with the volume on 0 it will play about a 30hz tone full tilt.

This just happened to me recently..

You guys know the alternator whine you hear out of speakers? The same thing is happening to your subs.

You have to put stripped wire around the rca inputs on your headunit. I just did this yesterday, and it works like a charm.

x2 They also got twisted rca's to help.

Its weird, cause I had this Premier hooked up to my Kenwood mono and it didnt do it at all. Then I hooked up my Soundstream amp and it didnt do it for a while. I then mounted it nicely on the back of my seat and it started to do it.

EDIT....

I think I know what may be causing the thump. I had my capacitor installed and it never did it. I had to take the cap out because I sold it and my distro blocks arent here yet so I put a bolt and nut through the ring terminals on my power and ground and electrical taped them up just temporarily till my disto blocks arrive. The positive and ground are about 2 feet away from each other, but I dont think that the amp is getting a good connection.

My 4 channel dose not thump at all tho..

a 30hz hummm at full tilt sounds like your signal wires (RCA's) grounding out.

Random burps would be a problem in the signal chain somewhere. Either noise being induced into the system from a foreign source, or your source unit/pre-amp has issues.
