[QUOTE="DarkScorpion, post: 6825032, member: 618537"] No, you cannot run active with those crossover settings. An active capable amp will typically have a multiplier button where you can select either "1x" or 10x" or something similar along with having both, high-pass AND low-pass selectors for a specific set of channels. That means when you're dialed in at say, 100hz, you can select the 1x option for a crossover point of 100hz, or the 10x option for a crossover point of 1000hz. This is important for a [B]typical [/B]active setup: usually you want your midwoofer to be low-passed in the range of 2000hz - 4000hz and high passed around 80hz (this is called bandpassing), and the tweeters to be high-passed at 2000-4000hz, depending on where your mids are, how low you want your tweeters, how steep your crossover slopes are etc. If for some reason, you wanted 6x9's to play just midbass, then yes, you could bandpass at say 80hz and 300hz. This is just a generic range, though. I'd actually advise against running separate 6x9's as midbass unless you REALLY know what you're doing and are setting up a proper 3-way front stage setup. As far as I know, there aren't too many active capable amps out there that aren't specifically targeted to the SQ market.
