extra wire on RCA cable?
 

I bought a RFosgate amp kit, question is- what's the use of the extra wire in between the RCA cable? Sorry for this stupid q....

That's the lead cable for switching on your amp with your headunit (I think that's what its called).

i got a different (blue) wire for that remote turn on (hedunit to amp).

You don't need the extra one of there is one on the RCA cable already. But now you can decide which one to use yourself.

thanks man! i just thought that running a live wire (remote wire on?) with the rca will affect sound quality.

I haven't noticed anything on my setup. The remote wire doesn't carry much voltage anyway.

Is the wire that you are talking about a very small wire? If so that is the ground for the RCA's ground that on the deck side.

I SERIOUSLY doubt it. IT IS the turn on lead as mentioned above.

On an RCA, the pin carries signal and the outside ring is the ground.

I disagree I will take pictures tonight of my RCA's so we have all have a clear understanding of what we are talking about.

try a search on sounddomain.com or caraudioforum.com they will both give you the answers that you are looking for.

It's DC.. it won't have an effect at the current/voltage that we're talking about.


If it's meant to be a "ground" then it could actually be a source drain. If the amp or head floats the audio ground from the power ground then tying them together would/could avoid a ground loop.

Its the REM Lead. Some manufacturers intergrate them into the Patch Cable for convenience, while others put them seperate to kill all possible sources of noise, and the fact that 99% of Amps have the REM slot in betweent he +12V and GND slots which is on the opposite side of the signal input/output.

Yeah I have noticed this :mad2: :mad2:

This will explain about the wires that are connected to the RCA's

That gave two different opinions. Is there a right one?? If you have noise problems, there are other issues with the wiring. Using the TO lead as a ground is a patch, not a solution IMO.
