Speakers making odd noise

[bloodhound50 10+ year member]

My speakers are amped at the correct rms wattage and ever since i got the amp installed my speakers are making an odd sound almost like a morotcycle idle. hthis is at no volume but the stuff turned on. then if i were to accelerate it becomes a more high pitched sound and like a motorcycle it produces the sound faster, same as if i decelerate or turn accessories on. when i turn it to volume 1 there is a high pitch sound like a whistle almost and as u turn the volume up from there as the music comes in it is hard to notice. also the two right speakers make this noise much louder than the left two. the left two you need to put your ear next to them to hear it. i have also used the balance feature and taken it off the right speakers and played just right speakers and it does nothing. there is 55 watts rms going to the speakers and they have factory cables as well from the speakers to head unit. i found it odd that only the right speakers are making the noise (i should say making it very noticibly becuase the left do it to) and i thought maybe there was a grounding issue or something? possibly it wouldnt make sense but im just throwing ideas out there.

might be alternator whine, i remember havin that, it ****in sucked, had to play the music really loud to drown it out, i'd reroute your wires especially your RCA's AWAY from the power wire, you don't have the power wire and RCA's runnin down the same side do you? i hope not

Is that Harmful or just really annoying?

Sounds dead on to alternator whine.

It's not harmful, but it's f'ng annoying.

x2 on letting us know how your wires are ran. Could be a number of things: high resistance @ ground being the first that pops into my mind.

yea well i went to the place that installed it and they said it was a 45 degree rca being too close and now its not really there but i am still using factory speaker wire

I just had the exact same problem with my amped speakers. It is apparently engine noise...to fix the problem, I wrapped speaker wire around each RCA plug and grounded it to the HU - note that grounding it to the chasis will not have the desired effect. Good luck!

Hold on a minute...you have an amp on your speakers...and they are still hooked up to the head unit? And who installed your system?
