OK for matching speaker to AMP the only spec that really means anything is the rated input power, or the RMS (Root Mean Squared) power. So if you are buying a single amp with a single stereo O/P I would pay attention to the spec of the Kenwood speakers rated input power of 200 watts & get an amp that delivers 200 watts per side max.
I deal in professional sound systems for musicians so I don’t know whats available in car stereos these days but judging from the speakers that you have I assume that you plan on using the kenwoods for your mids & highs, & the legacy for your sub-woofer. If they are available in car stereo versions I would look for an external crossover that goes between the deck & the amp. Then I would put my lows through a 700watt max mono bass amp, & my mids & highs to a separate 200watt stereo amp. You will need more power to drive the base anyway, the mids & highs don’t require as much power as the bass.
