Bro we never compare prices of audio stuff on their official websites , check amazon or sonixelectroinics , moreover prices are at higher end of audio in USA than in pak (talking about common brands pioneer ) in pak things come either from Singapore or china ,dubai so duties are less .
12-13k for amp when it came and jbl box price can be confirmed by @madhouse12
Sir I'm not interested , I've used the and sold the JBL gt512 3-4 times so was just a spectator

I bought new , which are so,d once again . The box is yours I had but I altered it a bit i have shortened the size of port to bring down the gunning frequency to 36hz . It's lying around now useless .
