I know its been flogged to death and information everywhere - but it just confuses the hell out of me..

So I'm wondering if anyone can give the thumbs up to these or should i be looking else where?

I don't want my money to be pissed up the wall and whilst i still have it want to invest it wisely in my truck.. I want to run them through my ctek d250s dual as its got the MTTP built in..

No1.?

No.2?
