I got four of these in my cavalier running off a Rockford Fosgate PRIME R300-4 and they sound amazing. The only issue i had with them is that one did blow, but i was giving it frequencies lower than what it is rated for so its understandable. I would recommend this speaker to anyone just make sure you stay within its levels.
