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..
