i recently bought all my stereo, but have question if i want to run active. I have pioneer p800prs HU and sundown audio 100.4 amp with 2 sets of CDT components. I havent hooked anything up yet, because i am building kickpods and redoing my door panels now as well as getting ready to build my sub box. But, on the 800prs, do i have to get a seperate crossover to run active? Also, instead of running 2 -4 channel amps, can i just run all 4 tweeters off channels 1 and 2, then run all 4 midbass off channels 3 and 4? thanks for any help, i have read hundreds of post on going active and now i have read so much, my mind is ******. LOL
