Query: Great Sound, Won't Last

I bought this SW about a year ago, AWESOME bass! I was very impressed with its sound quality. I compared it to much more expensive subs and found that the ASW10-120 outperformed them all, BUT...about 8 months later, it fried. It was on a 100w receiver that barely got turned up beyond 1/4 volume, but yes, occasionally it got cranked. So I took it to and electronics guru friend of mine who looked it over and and stated that the amp was built with inferior circuits, and that to rebuild it with quality circuits would be worth more than the ASW10-120 if it were brand new. My advise: Do not buy it. Just google ASW10-120 problems. If you think you will not be cranking your sound up very loud then you don't need a sub, but if going to crank it up buy something that can handle the power. Like I said this 120w sub was on a 100w receiver. It didn't last.
