Run length


Room layout dictates the sub is on the opposite wall. Not ready to run a wire across the floor. It would be 26 feet.

To skip the floor run I would have to go up and down inside the wall. That would add another 18 feet for a total of 44 feet.  Too long?  Will be using plain old 14AWG cord.

I have 4 JL F-113's. 2 are in the back of the room. One has about 50 feet of XLR cable running to it.  No problem.

Sorry I did not catch that your sub is not powered. Perhaps consider going to that type of sub?

It will not hurt anything if it is powered but if it is a passive sub you will need much heavier wire for a 44 foot run.
Is this an RCA (signal wire) or are you taking the speaker output to the sub ?

If a signal wire, make sure your wire is very well shielded.  If a speaker output, you are ok.

In any case, you can also consider wireless:
