I'm new to the forum and this is my first post after a lot of reading. (Hope I posted in the right place.) AVS forum has been a great asset and I thank everyone for all the great information.

So what is the best wire for an in-wall pre-out run of about 50' from the AV receiver to powered subs? The pre- out wiring will be sharing a chase with RJ-6, CAT-6 and a dozen pairs of speaker wire. I've got some extra RJ-6 but, could I run twisted pair or what ever is best.

Biggest problem with long subwoofer cables is keeping out hum from the AC. Assuming you have RCA connections at both ends, you will want coaxial cable with two high percentage copper braid shields. The Blue Jeans Cable LC-1 is an example of that. Audio baluns that convert to twisted pair might be another possibility.

I purchased bulk cable from BJC for this very reason. Give them a call or email they are very helpful. You will want a solder connection with a twisted core as crimps or compression dont work very well. Don't run them with a/c wires and cross the a/c runs at close to 90° as you can and you should be fine.

I guess I did ask for "the best cable" but I really meant cable type rather than pre-made. I think I'll try my RJ-6 which is double shielded plus foil and revert to the BJC if there are issues. Plus it's much easier to pull cable without RCA connectors. It's always good to know where to go if I need to step it up a notch so it's good to know about BJC.

The route should be fairly clear of AC with the exception of the 240V/60A line to my welder but I'll make sure they cross at 90 degrees and I won't be running the subs when welding. smile.gif Thanks for the tips. If you see major issues with RJ-6 feel free to chime in.
