Uneven sound distribution on speakers...?

[Kelli]

Hey guys. I have a question that's been bugging me for a while so maybe someone on here could give me any ideas on how to fix it, or has had a similar problem before.

I have a less-than-a-year-old turntable with a problem that has either gotten worse (or maybe I've just noticed it more) over the past two or three months I've had it. I connect the turntable through the auxiliary port of a stereo system that then is connected to speakers. However here's where I'm having a bit of trouble. When I play records on the turntable, the volume between the two speakers is VERY unbalanced. One will be quiet one second and then loud the next. When I increase the volume, one might get extremely louder and the other either does not, or will get louder or softer every few seconds... This makes listening to records sound pretty bad, even if it is one that had been brand new and unplayed before. However, these same speakers sound perfectly fine when I play the radio or cds through the stereo system. It's only when turning on the auxiliary to listen to records that I have this problem.

I don't think it's the wires/connection because those are fairly new as well.

Any suggestions? Am I doing something wrong?

I'm not the best person with this sort of thing, so thanks in advance if you read this.

Knowing my luck I'm probably just missing something very obvious.
