Okay, I have a pair of eclipse 8263 6.5s in the front (40 W), infinity kappa 6.5's in the back (i'm not sure about the wattage on them). They are powered by a Kenwood KAC-645 4x45 amp (rated 25x4 at 4 ohms, 35W at 2 ohms). I believe these speakers are 4 ohms (just a guess there).
Tweeters are Alpine 6017, 30 W RMS.
My second sub is a pyle millennium PL205 (250x4, 350x2) with no woofer picked out yet.
So I guess I need woofer/box suggestions and crossover ideas.
Thanks!
