Hi, very great forum, can you tell me the dimensions of this subwoofer? Thanks

Ive just bought one of these subs, and I have a query regarding the audio wiring... as am having a look at the bit of loom that came out of the car, and think it might be balanced audio.

 

Which is where it basically has two signal wires, one being out of phase of the other, and then a separate braided screen which is only connected at one end.

 

So the brown and yellow wires are the two signal wires, and the black/orange is the screen (which explains why it isn't connected at the sub end of the wiring)

 

For those that don't know about balanced audio is used on professional audio gear, studio stuff, and for long cable runs, as you don't tend to get any interference.  Which makes sense why they would use a balanced audio connection for these, as the same bit of loom carries power, and some parts of the audio wiring aren't even screened, and am sure you would get interference otherwise.

 

I cant deny that it probably works okay as shown in the wiring diagram, but think its wrong, and would work a lot better if wired using a balun, to convert the normal un-balanced 2-wire audio output from the head unit, to the balanced 3-wire system used by the sub.

Sorry to bring this back from the dead but do you have a link to the Balun you referring too?

 

thanks
