I have this wired to my Pioneer GM-5500T amp in a vented box in the trunk of a 95 thunderbird... and this thing hits HARD! Just as good as my friend's 15 inch apline, but not quite as loud. But it is hard to believe this sub is only a 12. After bumping for 15 min my heart started to hurt haha. It has the perfect amount of bass too, it wont distort the rest of my music. Buy this sub if youre thinking about it, really inexpensive but hits wayy harder than you ever will expect.
