stephendunn,
Sure,,,,no probem.....but then you do not get to tune your system with different flavors of speaker wire. And, as debjit said....experimenting with wire is made very hard. If you have mono blocks then absolutely you can mount them right behind the speaker and use the wire coming out and hook it right to your amp posts...using the wire tinned (no spade/banana....all connectors suck)..
debjit_g,
Most speaker wires are not shielded.
