couldn't find a thread on this, so hopefully there isn't one out there lurking.... i have an "ashdown 500 abm evo II rc" series amp. tonight i'm going to finally try the "sub out" jack. the amp has always given me such a great sound and tons of lows through my eden 210xst and 212xlt cabs, that i have never gotten around to trying the sub out crossover. we're playing an outdoor gig tonight, and i had thought about running the "sub out" crossover into a powered sub that i would rent, but instead i'm going to run it into our p.a. system. i'll travel light, running the amp into my ampeg pb210 cab, and as mentioned, the lows (from the sub out jack) will run straight to the p.a. has anyone played around much with the sub out jack and what kind of powered subs, p.a. systems have you run it through and what kind of results have you gotten?
