component speaker ohms

Hey, this is my first post. I've been on here for hours searching this question out, so i hope i'm not being redundant. my question is if the component kits says 4 ohm impedance, does that apply in the same way to the mid and the tweeter as it would to say two 4 ohm woofers? are the mid and the tweeter 4 ohms each? would the calculations for ohms law be the same for selecting an amp? and does a passive crossover affect that in any way? Thanks Jman

It is a 4 ohm system. The crossover makes sure it is 4 ohms by making the woofer "invisible" below the crossover point and the tweeter "invisible" above the crossover point. It says 4 ohms, so get an amp rated for your desired power "into 4 ohms".It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Thanks, thats exactly what I was after! I really appreciate it.
