What speaker gauge for my setup?

That makes no difference. Both speaker cables should be the same length. Coil the excess on one speaker.

Coil? Are you sure? Won't that add resistance?

This certainly will add inductance into the circuit. The amount added depends on the current as well as the number and size of the loops. If one has to, folding is by far the better solution but still not recommended. Cut to length, wire can be relatively cheap..

Pulled some 12 gauge wire from my 18" sub downstairs in the largely abandoned man cave that I planned on not using anymore. Well, it makes a big difference. Despite having some superficial damage to the exterior caused by my destructive cat the cable works great and is MUCH MUCH better suited for the high powered class H amp. There are teeth marks everywhere in the plastic but no puncture down to the copper. Sound is more rich in every way. The bass has now extended and the highs don't sound as strained. I think this realy shows that for a high wattage application speaker gauge is very important. Sometimes DUH applies. 18 gauge is for consumer appications in low wattage short distance not for professional use.

That's why I keep the 20 extra feet of wire that I have for my right speaker in a tangled mass, shoved behind the cabinet and on top of the power bar.

My speaker cable is mostly 12 ga. Does the rear speaker require equal length cables.
