    I'm thinking of upgrade the stereo system. I found component speakers that I like; JBL MS-62C. I want to find an 4 channel amplifier for it but the specification got me really confused.

    JBL website - nominal impedance: 4 ohms and RMS: 80 watts

    Sonicelectronix - impedance (per voice coil): 4 ohms and RMS: 160 watts per pair/80 watts each.

    Do they mean......

    1) 1 woofer and 1 tweeter after connected together has 4 ohms and rms: 80 watts

    or ......

    2) 1 woofer and 1 tweeter each has 4 ohms and rms: 80 watts; after wired together has 2 or 8 ohms (not sure) and 160 watts

    or ......

    3) 1 woofer and 1 tweeter when they connected, the pair has 4 ohms and rms: 160 watts

    I can't decide which one is the right information.
