Ok, maybe it doesn't rule, but it's pretty damn good. I actually drove my truck 55k miles so far with no rear sub. It didn't come on my truck when I bought it and I didn't really care because at the time even everyone said it sucks. I'm no audiophile--and being that my two other vehicles don't have radios (motorcycle + stripped race car), any radio is actually nice. But I actually avoided buying a stock sub for the life of the car based on how much FJ Stock Sub bashing went on on this forum--and what a mistake. Tonight I installed a used one and am very happy. Lesson # 240: don't believe everything you read!
