Speaker and Subwoofer wiring questions DL 04-01-05

I am in the process of finishing my basement and have run speaker the
in-wall Monster CI-Pro for the speakers. I have a couple of questions to
make sure that I have things set before I install the insulation and
sheetrock.

1. I have run the mid and rear speaker connections to a central location
where the HT equipment will be located. I would like to do the same for the
subwoofer line(s) (multiple runs for flexibility) as it is a convenient
channel to run the wiring. For a 6' distance, the speaker wires are run
next to the power (110v 12-2) wires. Will this cause a problem? I was
told that this might cause interference with the speaker or subwoofer
operation.

2. Not seeing any bulk subwoofer in-wall cable, what type and gauge of wire
is best for the subwoofer connection. Can I run more of the 14 gauge CI-Pro
and solder a RCA connection to meet the wall jacks. Does it need to be
heavier gauge than 14? I am installing multiple SW runs to allow for
locating the SW in different locations in the room. The longest run will be
25'.

Any guidance would be greatly appreciated.

David

Use a RG6 or a digital RG59 for your sub cable. I have a tool that does
compression fittings and you can install a RCA type if you want on
either of the cables. 14 gauge is more than enough. You could get away
with a 16 gauge if you really wanted too.

Thanks for the fast response.

I have plenty of RG6 Quad and compression fittings. Any thoughts on the
speaker and subwoofer wiring next to the regular power 12-2 lines?

Running speaker wires right next to AC lines is not a good idea. Depending
on what kind of load is hooked up on the AC (especially fluorescent lights,
or other induction devices) you may get a get a more or less pronounced hum.
Speaker wiring should be at least 1 foot away from power lines, especially
if it is a, say, more than2 ft parallel run. Crossing AC lines is o.k.
