hey buddy,dont take their inputs as theyre saying your equipments are all crap.me myself didnt want any of those,i read threads and asked people who had experiences with products.that's how you'll know a good product is or just test it yourself.these people like bumpin buick,gmcjimmylt2000 etc are guys who had an experience with those what you have..
it sounds like they're putting down your equipments but really they are helping you and letting you know more about audiobahn line.
try to send it back where bought them and ask these "sirs" about your build..PROLLY your next equipments will be better or maybe one of the BEST around..just ask the PRO'S..=)
if you still want these equipments to be installed and you want to find out about setting it to 2 Ohm,put the specs of the sub and the amp so the people will know..
