I just installed my ed 9.1 friday night. It worked fine, I set the gain using the method stickied in this forum. While I was driving around Saturday with it pushing my sub(man did it ever pound), it just cut out. All the fuses are intact, and it still turns on. I tested the rca's on another amp, they work fine. Tested the subs VCs, Dual 2 ohm, both read 2.3-2.5. Tested the speaker terminals, and I didn't get any voltage reading. Did I mess up somehow setting it up? Or did I just get a bad amp. I'm going to call ED on Monday and see what they think.
