Alpine 3555 - Balanced or Unbalanced - Coax or Twisted pair?

[MrFriskles]

Hey guys getting down to ordering wires for my new setup, does anyone know how i could figure out if my amp (an old school Alpine 3555) is an unbalanced or balanced input? A pioneer DEH 610BT is the headunit. Current wires connected to it are Coaxial, sound fine I guess. Is coaxial wire the "default" if you dont know what they are? Was reading somewhere that twisted pair isnt effective unless used on an amp that does balanced load on its inputs.

The run is 20 feet in an 1995 M3 Coupe.

Balanced cables use a BNC connector like this-

Most car audio uses RCA connectors, and in a car those twisted pairs help reject noise.

Ah OK, Definitely RCA type then. Coax vs Twisted, seems like from what I read twisted was a better technology?

Also thank you, that's the first time i have heard anything about a different connection with balanced/unbalanced.

Rich B, thanks again for the information.

Ended up reading a good thread that elucidated coaxial vs twisted pair.
