I hear my CD Player through my sub??

[Tony991]

I hear my CD player through my Sub.. and no I'm not being an idiot. lol When i have a cd in with the volume turned to zero i hear "bumb bumb bumb" coming from my sub all the time. Then, when i take the cd out and turn on the radio (with the volume turned to zero) there's no noise.. And when i have just the radio on (with no volume and no "bumb bumb bumb" noise) and i turn on the dome light it goes "bumb". and i can hear my fuel pump through the sub also, not sure what else makes it go "bumb" yet. But if someone can tell me what's wrong that'll be great...

Hello There,

i'm steve and i'm new to this site as of now, anyway... i've had that problem in my saturn and explorer, from my Understanding, it's because you either have the wiring connected wrong, or there is some sort of a power shortage. Or the one other thing i tried was sometimes my 80-100 Watt fuse near the battery wasn't in all the way. hope to hear back from you. later.

Try makign sure your ground is good

Ok i found out what the "bumb bumb bumb" sound was.. It was a bad ground from the amp.. There was paint on the bolt, so i just wire brushed the paint off and put it back and the sound went away.. BUT! lol I still hear my fuel pump through my sub. There is a good connection at the fuse in my engine compartment. So do you think it could be a power shortage? Would that cause the sound of my fuel pump to be heard through my sub??

I had a simaler problem in EVERY vehicle ive wired up, so I just use this:

They sell them at Walmart, Meijers, AZ, etc, its about 15$ it plugs into the RCA inpluts on your amp, and you hook the rcas from the headunit going to the amp, into the other end, and it solved ALL my whining and thuds
