I did this on some crappy Nitro amp I had, because the pwr and gnd terminals are opposite of most amps, so I was just going by muscle memory. Blew the inline fuse, replaced it, and had no problems.The biggest piece of advice I have for you though, would be to use some motherfucking punctuation. Your posts are almost rendered entirely unintelligible because you manage to avoid commas and periods like the fucking plague. ENGLISH. If you can speak it, type it. It makes everything so much easier to help you with, and so much less frustrating to sift through.
Now that being said.... I did manage to pick up that you think your Scoshe amp is good. It's not. It's a very low quality amp. If you can afford a new Kicker amp, there's a lot better value amps you can get used that will perform just as well, if not better.
Also, you said something about those mediocre subs, on your mediocre amp, in (what I'm assuming is) a mediocre prefabbed ported box, somehow managing to not only flex your rear window, but actually start to crack it? I know that to be a bold face lie unless you're an expert in acoustics, and already had a badly damaged window. I've been in much louder cars and seen some significant flex, but I've never seen a broken windshield be the end result.
