Ok, so I recently got a set of Focal Polyflex 165h. The one thing about the set that I found odd is that the dont come with a true crossover, just some bass blockers for the tweeters. I was wondering if it might be in my interest to just run them active (I have the Alpine 9853) using my hu. Now the thing is, i only have a 2ch amp. Would I be able to run the tweets off the deck (its says it does 18w rms) and the mids off the amp? Also, where would I want to put the xover at? Thanks for any adivce you people have to give!
