Actually, no, I use 2 runs of 12ga wires, then braid/twist them to make '1' run of 9 ga wire. Hey you gotta use them for something after you buy a 250ft spool
With the amp, I don't think you should/could use both A AND B speaker outputs with 4 ohm speakers. The manual, all 4 pages of it (!), recommends at least 8 ohm speakers if you to use both speaker outputs (someone with a better grasp of the physics behind this can explain it).
I think cabling will play a large part in the sound you get though. I replaced the factory jumpers an actual pair of ICs, and that really tamed the trebles (for the better).
Good luck!
