RCA issues

[XxSuperAdamxX 10+ year member]

I have a Monster Cable RCA hooked up to my subwoofer amplifier and Knu Koncept RCA hooked up to my speaker amplifier, but sometimes when I make a left or right turn on my car, I hear static noises and sometimes when I go on bumping roads the static occurs again. I took out my headunit and messed around with the RCA's by tapping on them and it makes noises on my speakers everytime I tap on them. I find that weird to hear noises everytime I tap on the RCA's and i'm wondering if the RCA's are bad or is there interference going on or what? If I can get some recommendation on this I would appreciate it very much. Thank you.

I dont think its the RCA cables, but a grounding issue. Anybody else have ideas to help this fella out?

Try switching RCAs. It might be a bad one. It could also be a loose speaker connection.

Does the noise occur in all speakers?

Yes it does. Everytime I mess with the RCA's it creates some static noise.

I dont know if its just me, but it sounds like a bad ground, and engine noise/whine. It would possibly be just a short or ground, since when you take turns in the car, the wire could be moving touching a metal causing a short or some static interference. Im not sure, anybody else?

Sounds reasonable, there is engine noises when I turn on the car. How would I fix that grounding issue? My friend told me to put an O Ring on the RCA's or something.

Well, the first thing I'd check is make sure the RCA's are as far from the power wires (myth or not, cant be too safe) and make sure the ground on the chassis is clean and installed good. Thats all I got, anybody else help this guy out.

Well I think I might of resolved my problem. Well, I had to wrap the RCA's with electrical tape so it wouldn't make metal to metal contact, i'm not sure if that's grounding problem or not, but it has got rid of 90% of the static noise. I still hear engine whinning noise though when I accelerate on my gas, but that would be a pioneer problem from what I heard in the past, or I need to sand down my ground. Thanks for the replies, but if theres any other advice I can check on it would help. Thank you.
