well, heres the deal. my cousins subs are making a bad HUM noise and we are both not sure what it is. i figured i would post on here and see if i can get any ideas on what the problem may be.

a few noises that ive noticed are.

1.) general light hum while the deck is on (subs are on) which is constant.

2.) a bigger hum when she turns the system on. (more like a thump)

3.) when the interior light is on it hums louder and than when the light slowly fades off the hum noise fades aswell.

im guessing its a power issue but im not sure from what or how to fix it. i have a few ideas but i figured i would see what info i can get first.

thanks

 

As a relitive newby to this type of thing,I want to take a stab here...sorry if I am wrong....

My guess is a ground loop...

Had a very similar problem with my Pyramid amp before and thats what I was told...

Not too sure what exactly it is..but...

Can some one either back me up or show me where I am wrong here?

I too would like to know what it is...

 

aight thanks alot. ill check them tommorow and see if the hum gets resolved. i was kinda thinking it may have been the grounds but i wasnt positive.

 

Ha ha! I love the unintentional play on words!

hmm.. i went out and looked at the ground wire. its hooked onto a big *** bolt right in the middle of the back of her trunk. if i did move it im not sure where else i would put it. ive looked around for different areas but the only other screws that i found where quite small and part of the rear light wires., and im not up for drilling a new hole.

any ideas?

 

well.. shes getting a whole new system in her car now anyway so we can fix it once she gets her new set up in.

thanks for the help [img]graemlins/thumb.gif[/img]
