I have a good deal lined up on a blown 1100a2 and got a local guy that can fix it for a reasonable price. But! I seem to remember these amps failing a lot back in the day before the 1000a2 replaced it. Am I imagining things or were these amps unreliable? I'm won't be running it under ohm and don't push my amps very hard but if I have to fix it once a year I won't bother. Thanks fellas.
