I would go with the same brand amplifier. Kicker makes great amplifiers. I’ve personally used Rockford Fosgate Amps with larger Kicker or Redline speakers
The wattage on amplifiers in my opinion , does not have to be exact matching of speakers max wattage. Moreover , the more wattage amplifier and of a brand name , the more expensive. It is better sound quality to have correct wattage max rated to amp , but keep in mind when you go over max rated speakers will blow !
