Is 35’ and 50’ to long for RCA sub cables?


I have four subwoofers now and want to run cables for the rear two. If I ran them along the baseboard and tucked them down underneath I’d need about 35’ for one sub and about 50’ for the other.
Is that to long of a run for RCA sub cables?

Well now noisy is it? If it's quiet and didn't loose signal strength, what's the issue. If your having a problem with RFI, or EFI  that's different..

Enjoy..
I’ve been told to run XLR (mic) cable and the. Just use the two conductors for RCA. Would that help even though my subs don’t have XLR inputs?
