Hi, according to the cable size chart I shuold use a 4 gauge cable witha 70a fuse. what will happen if I will use a 10 gauge cable with a 30a fuse instead? I need to wire two amps with a total of 340 watts.

What cable size chart are you looking at??  But nonetheless, for your situation you should use a minimum 8 gauge (never use 10 ga. or smaller, please) with a fuse at the battery anywhere from 40 to 100 amps.  Split the power wire to the two amps through a fused distro block, and those fuses can be ~40 amps.

I see, my cable is about 10 feet long, how can I wire the two amps without the distro block.

You can't get one, or you don't want to get one?

Well, you can get wire and fuses and fuse holders, apparently.  So run two wires back from the battery instead of one, fusing each at the battery per my description above.

The most cheap ghetto way is to link the 12v cable from one amp to another lol so you connect 12 v to one amp and from the same amp run it to the other 1

Don't do that- especially if the amps don't have their own internal fuses. 
My ex once told me I have a perfect face for radio.
