Can i used this for my mid voice or is it for bass only?

You should have a subwoofer to do this properly. I had a double 15" woofers with 10" horn and (4) 4" tweeters which was one tower by Rockville and used with a Rockville 18" subwoofer and it worked great.

What are all the components i need to connect this sub in a room 3.5mm? will someone link me them?

Your question doesn't make sense, using a 3.5mm connection? Will require a sub amplifier and most likely 3.5mm female to rca jack.

I'm planning to build 2 of this speakers in a speakerbox but wich amp can I use best to power the subs?

In response to the first answer: any 5000 watt amp would be excessive and ultimately would fry your two speakers...unless you want to wire 4 of these in a series-parallel wiring, 5000 watts is wwaaayyy too much.
