Could very well be a bad solder joint inside the amp....

Answer 4

I think what you're experiencing is some sort of interference caused by the cellphone.  I get it all the time at my computer at home, work, and just about anywhere there are speakers.  My radio alarm clock does it too.  When the cell is within range of the speaker/amp system.  The phone doesn't have to ring for it to happen either, but the interference is caused by the phone none the less.  I've seen it many times.  I can't give you the particulars of it, but I'm sure that's what you're referring to.

Answer 5

check your pwer connections make there is contact to any of your inputs from power wire touching them

Answer 6

What you are hearing is the frequency waves from your cell phone ringing coming thru your speakers.

This will happen if your cell phone is next to a car/home stereo,computer speakers,guitar amp,baby monitor....etc..

You will hear a weird vibrating noise,sounds like a popping/vibrating combination.There is nothing that can be done to correct it...it is normal.

Answer 7

i would check ur ground connection, make sure it isnt lose and make sure the paint is scraped away. my bro had the same problem and it turned out that it was bolted on painted metal so he scraped away the paint and it was fine.

Answer 8

Possibly a bad ground causing static.

Check your amp ground.

Maybe even your RCA cables running from your deck to your amp are bad and causing a static noise.

Also double check to see your sub wire running from the sub to the amp are nice and tight connected well.

Possibly your deck ground is also bad check into that if nothing else mentionned works.

What kind of deck? Some decks are worse than others for noise comming through the deck filter. I had an old Pioneer deck about 3 years ago which had a bad engine noise filter and I heard static and some engine noise often when the amp was off or deck off.

Also, see if your fuse is still nice and tight not sloppy or loose. Adjust it ot cut it off and replace it with a whole new one, but simply keep the old power wire. I just recently did that with my wiring. Had an older 40A fuse(kicker fuse) with a 12g wire but the old fuse fell out somehow so I all I did was cut my new Tsunami 40A fuse that was lying around and stuck the 12g wire into it and hooked it back up.
