My take, others may correct me
Components in question, Hertz (2-way) can be run active via both, the Alpine amp Imran has F505 and Kenwood x7013u HU combined.
The frequencies can be set for independent drivers via the amplifier itself (built-in controls) to create a band pass filter. For simplicity we say that tweeters go 1khz or more while 80hz to 1khz is left for midbass and less than 80hz for sub.
For tunning the drivers, the HU supports independent TA for all drivers. So that can be done via the HU only. (cm's)
For EQ, limitation is in 5 bands only so that can only be adjusted as per listener's preference. (62.5Hz, 250Hz, 1kHz, 4kHz, 16kHz)
Furthermore, to run the power solely from the amplifier, the build in amplifier can be turned off (Amp mute option) from HU
