S2 and S3 are tough classes, you bettah have an SUV or an extended cab if you wanna place anywhere near well. I know too many locals in Louisville that can almost pull off 150's in BOTH classes and hold their fuse just fine. But Kentucky is MECA street class country fo' sho'...
Park and pound is dumb. Just sayn. I've done it a few times and did ok, but my setup isn't even designed to do that shit to start with.
As far as all the anaba/knockoffs these days...who knows. Ive met a few idiots selling stuff thats been rebadged china crap, so I think its spotty as far as brand ownership goes these days. But then again, anyone with 30k with disposable cash can start their own amp company.
