I had a friend who fashioned some speaker wire from 4-gauge jumper cable lines. It kept breaking the terminals. He put battery posts on his speakers. I forgot what he did with the amp.
The difference in sound was extraordinary! Well worth the continuous hassles of the setup. NOT!
I kept telling him, "What about the many feet of 22-gauge wires in the amp and 18-gauge in the speakers and crossover?"
Him: "That's not important! Can't you hear, no
FEEL, the difference?"
Sorry for the off-road trip there. Carry on!
