Buzzin sound from Speakers! HELP

[Lexoboi 10+ year member]

OK, i have a real freakin issue here. the buzzing sound only comes on when i connect the second amp which is suppose to be for the components.

i check the RCA's, i Rewired everything..RCA's on one side the power wire on the other side. i went to buy a Ground loop isolator DOESN'T WORK.

i tried grounding the H/U to the body of the car/ Doesn't work

i ran 1power wire to both amp with a splitter

same with the negative

i have a Eonon Flip Deck. Everything is fine only the **** second amp and the noise.

my sub amp: 1000watt 2 channel

my other amp is for components

what is the correct way of re-connecting everything with fresh wires.

i tried separating the negative wire SAME-THING.

i tried about everything, & i did read the other thread n it didnt work for me..help!

Check the ground to your speaker amp. Scrap away any paint that the connection may be touching.

You may also have crappy RCA's or some low end amps just cause that to happen.

When I had a Walmart amp hooked up to my speakers they did the same thing. Then I got a decent amp for them and they don't do it any more.

It could also be alternator whine which happens quite frequently when it gets colder outside like this time of year. I believe there is a sticky on alternator whine that might help you out.

i had cheap RCAs and they worked fine. i would look at your ground again. get all the paint off. maybe run an extra ground wire. what amp do you have?

could be a cheap amp, ive had that noise with a cheap amp and the gains to high.

yeah i do got sum cheap amp..my sub one is Sound stream 1000watt n i'm using a cheap 1000watt amp for my components...but wen i turn the gains down on the component amp the noise goes away so maybe it is the freaking amp..do u guys think i should try rewiring the components like amp wire straight to speaker instead of wiring RCA from head unit to the amp back to the head unit on the components.

imma cheack the ground again, get bigger and new ground wires, n get new that gage block spitter thingy. thank guys im going to let u guy know wut happens after i do this..if it is still making that noise imma just take it to the shop or get better amps

I'm having this exact same problem. I have my component amp running with no problems, then i split the rca to run a second set to the sub amp and i get a faint ringing noise in the component speakers. It doesn't make any sense to me that I would get noise in my component speakers from plugging the rcas into another amp.

Initially I had the second set of rcas running out of my component amp's rca outputs so i thought it was something wrong with the component amp, but i still get the noise. The really weird part is that my component amp is 4 channel and if i split the rcas and run them into the component amp's second rca input i dont get the noise.
