I'm far from an audiophile and need help with some wiring. I have an
old pioneer receiver that has an A/B switch. I use B for satellite
speakers on my deck. Until recently, they worked fine having run about
30 feet of wire from where the receiver sits to the speakers.
Yesterday, I moved the receiver to a room farther away and had to
splice in about an extra 20 feet of wire. There are actually three
splices in each wire now due to obstacles and such. Now, when I turn
up the volume to even a moderate level the receiver stops transmiting
the signal and starts clicking.
Eek. Three splices and you expect it to work properly? Every
time you splice a wire you loose 2-4db per splice.
Huh??!?!?
Are you assuming he spliced it with Elmer's glue?

Three, plus
the connectors on the end... That's going to add up to a noticeable
load increase on the receiver. Splicing bad.
I presume the extra wire I added is
the problem. The wire I have been using, with success in other parts
of the house, is using a load of telephone line that I came in to for
free. It has eight wires in each run so I split 4 positive and 4
negative. It adds up to roughly 14 gauge. I have checked, re-checked,
and re-checked again all the connections and they are correct so I
presume the runs are simply too long for the wire I am using.
I'd re-run it with two pieces of 12 gauge wire. Those 4 pieces of
telephone wire aren't 14 gauge, btw. The look like it, but in terms
of capacity, they are closer to 20 gauge at best. This is a common
problem people make, in fact, with cat-5 and simmilar wires. It takes
a lot of them together to equal what one (by then, with the insulation
factored in) decent wire will do. Not that it isn't possible, but
most people find it cumbersome compared to using plain 12 or 14 gauge
stranded electrical wire.
Another option might be to get some Romex and run it under the house.
Another option might be to go with self-powered speakers. Then you'd
just be sending a preamp signal which should be no problem.
(Or just get a small amp for the second room - the best solution of
all, IMO)
