Bang for the Buck

Got 2 of these in the Hatchback Ported Pro Box and it shakes my rear mirror so much after 5 big hits all I can see are my back seats. Literally!
Running the FLI monoblock 1000w max amp to both of them. They give good quality and are built from strong material. And the pattern on them is really hi tech looking. Its kind of like golf balls in a way.
