Can i run 8 speakees on this?

I currently run six on just 2 channels. Pay attention to the ohm load and properly set gains with a multimeter prior to playing.

What size fuse this amplifier carry

For every 100 watts of RMS power, you will want a 10-15A fuse. So if you have a 1,000RMS watt amp, I would run 125A-150A fuse.

Would this amp be appropriate for skar audio vxi65 360-watt 6.5" 2-way component speaker system?

This is a class A/B 4 channel amp. It works great in your application.

Will this amp power 4 skar audio sk 6x9s good i got 2 skar audio vvx 15s on a skar rp 2000.1d and i don’t want the bass to drown out the voice

Yes, this amp is shouldn't be your concern. I'd be worried about those 6x9s handling this amp. I say that because though I really like Skar I've had no luck with their 6x9s. Good news is I haven't owned these sk 6x9s so you may be in luck. This amp is powering a pair of audiopipe CSL-6904 6x9 & a pair of Infinity KAPPA-93iX 6x9s in my car with a Skar EVL-15 pushed at 1 ohm with an audiopipe 1500w monoblock & fixing to strap it. The clarity of the 6x9s are wonderful at any level.
