Im running 14 ga to both, one is going to be about 20 ft and the second is going to be around 35 if I do it this way. Is this difference going to be an issue?
The issue is not the length, but the resistance of the wire which is dictated by its length and conductivity.
Electrical signals flow through speaker cable at over 100,000 miles per second so the time delay is negligible in any reasonable situation.
As others have pointed out, 12-14 gauge speaker cable is almost a certain guarantee that no matter what, the speaker wire (if properly hooked up) isn't a sound quality issue.
The most common problems with speaker cable is the connections, especially shorting, loose connections, or polarity reversals.
