I recently bought a couple pairs of Monster Cable XLN rca cables, but on one end of each set, there are a couple bare wires coming out of the casing. I am stumped what these are for...cd changer maybe? anyone know?

 

its a ground wire that runs through it. but u dont need to ground it all. i just electrical taped it off, no biggie.

 

i believe it is intended to be used as the remote line

 

That is what I would think. My last set or RCA's had the remote with it.

Is correct this is extra shielding to protect against noise.

According to Steve Eckblat (sp) sorry Steve..and others who posted on here
this is the audio ground. Its allows better isolation of noise by not giving the
signal a return point.

have fun

</TD></TR></TABLE>Ground is a return path. By tying two components together the idea is that the two grounds will be at the same potential. So you would ground one end to the radio and the other end to the amplifier. Noise comes from having two different potentials (not all noise), if one ground is slightly higher or lower than the other ground then current will flow.

10 + years ago this was a must when installing bigger systems , HU then processers, then x-overs then the amps, we would have to custom make the RCAs, we would use a double shielded interconnect , isolate the outside shield at the HU, then connect the outside shield to the sig, ground, [inside shield or, in the case of monster wire, the sig. ground wire] on all the rest of the RCA ends, [up and down stream of all componants, ending at the amp] this worked because any "noies" picked up by the outside shield had no path into HU, [outside shield isolated] could only "travel" down stream to the common grounds of the RCAs sig. ground to be "dumped" into the cars chassis.

I also have to agree with nsxxtreme......

I always use that wire for "ground loop", never for amp trigger, and if the RCAs do not have this wire, then I will run one along with the amp trigger, just in case, although not needed most of the time, if there is noies, then connecting this wire at the amp, [already connected at the HU] will get rid of noies, or let me know ,very quickly, that the problem is not because of a ground loop between the HU and processer/amp, saveing me time. And time saved, is good time. 94
