I think I remembered saying to the op.. oh yeah> "..if your NOT gonna keep the amp for life.."
It's simple: if you wanna get louder and you have $$$, buy another amp or run the Kicker 1 ohm. If you really care so much about the amp and you ain't got the dough, how will I be able to hear you? Hey there's quite a few people running that amp at 1 ohm and are still going years strong.
Depends whom is using it respectively. Yes, anything can happen and it will. Not everything is built the exact same. Even cars & their engines. Some last a really really long time but, some will break down sooner. Luck of the draw.
