    Need some help, I am completely dumb when it comes to audio and I ordered the
    $260 Alpine KTP-445U Universal Power Pack
    Alpine KTP-445U and some Kicker 40CSS674 6 3/4" components for my front doors. The Alpine amp is rated at 45w rmsx4 and the speakers are rated at 2-100w rms with a sensitivity of 90. Should this be alright or should I look at some other components with a lesser rms rating?

    Running a 100 w rms capable speaker with a 45 w rms amp channel is completely safe, and the speaker will probably sound fine. When it comes to coaxials or components, the rms power handling rating will be higher if the speaker is capable of cooling itself constantly, but it doesn't necessary mean the speaker will sound better at the full power rating of the speaker (high volumes).

    You will be fine. With a 90 dB sensitivity you can get away with a lower powered amp. The higher the number, the less power is needed to achieve that dB rating.
