ok i got 2 of these in my 1990 ford ranger and i recommend these for a great sounding sub or a teenager wanting boom i wudnt put more than the wattage shown but they sound great & beat hard i dont have the box to the specs but they sound great and PORT THESE SPEAKERS!!!! they need to breathe i can always count on ROCKFORD FOSGATE

These are great subs! and CHEAP! i was so surprised that Rockford actually came out with a cheaper sub. they are pretty simple but they sound good so far.. i dont have the correct air space for them yet but even when they're suffocated they sound good. with the correct box volume i'm 100% sure they'll pound(for their wattage)
