Hifonics1200W RMS A/B 4 Channl Car Audio Amplifier

How many Watts per channel? Not ohms per channel.

Can this power 4 ds18 mids at 250 rms each and 4 skar super tweeters at 100 rms each? All are 4 ohm

Is it 4 gauge ?

What is the rms per channel, i have 4 jbl 6.5in midrange speaker it’s 500w rms each will this be able to handle all 4?
