sifu sifu ice. I have a question. I want to go full active crossovers in my ice setup as i heard active is better than passive n easier control over my speakers. I have a 3-way setup up front, a 8' kicker freeair on my passanger floor well, and a 10' soundstream rubicon SQ woofer at the boot. If i ditch the passive crossovers and directly connect my 3 way speakers into every channel on the amp, can i do this? example.

4 channel amp.
channel 1 and 2 *HPF/FLAT/LPF* i use my 3' speakers on this (running of flat)
Channel 3 and 4 *HPF/FLAT* i use to connect my tweeters (running on HPF)

4 channel amp
Channel 1 and 2 *HPF/FLAT/LPF* use to connect my 8' sub (running on LPF with different low frequency)
Channel 3 and 4 *HPF/FLAT* use to connect my 6'5 mid bass speaker (running on HPF)

1 Monoblock Class D (set to 52hz) to run my R10SQ sub.

My main concern is, can i do this? how many active crossovers do i need? for example there are 3 way and 2 way crossovers out there. What would i need? Do i need both? or should i just keep my current setup? Im currently running 2 amps at the moment.

4 Channel Amp
Channel 1 and 2 bridged running my 8' front woofer at LPF
Channel 3 and 4 for my 3 way components in the front running HPF

1 monoblock amp
running my 10' sub.

Need some replies. if my words are too complicated, i can make a TL;DR version. thanks

but what if i want to go full active? what do i need?

2 separate subs to be exact. both tuned to different frequency.
