Is there any way to make SSAO more stronger, because the one i downloaded
off here is very faint and can`t make it out in game.

Please, post a .blend with that AO or script. There are multiple SSAO scripts around. Some work better, some don’t. There should be settings in the code like radius, samples, jittering etc.

You could just play with tweakables till you get your best result. There are a lot of options, like noise amount, samples etc.
