Just wondering what you guys thought about factory-rewned subs, soundomain has factory-rewnewed image dynamics IDQ's for $79. They have a 14 month warrenty, looked like a pretty good deal to me but I've never had any experience with factory rebuilt stuff. I was thinking of recomending one to brother who needs a sub for a 94 legend L, sq would be the primary concern, but it needs to hit hard too.
