Thanks heaps pplz!..

SOo therefore i'l havta find the same sub as wat ive got now..

is it Alrite to run both subs... say 600W off one 1200W amp??

..
does it make a diff wif the enclosed box that u put it in?
coz my subs says recommended for 50L or sth.. wat happens if i put it in a smaller sized box?
