Quick question- does it hurt to run the speaker and electrical wires through the same holes instead of drilling double holes through everything? I don't want to run into any problems with the wires touching each other but if it doesn't matter I'll put them through together. I don't know to much about the workings of wiring and what causes interference or other problems, so thanks for the info. The speaker wire is 12awg and I also have 1 sub cable. Thanks again!
