I wrote a review on the day I got the subwoofer installed so this is my follow up. I am still astonished by this sub every day that I use it. The bass is clear and unbelievably loud. There is zero rattle within the unit itself, and the trunk is dynamatted so that is quiet as well. I definitely recommend this sub to the average person who wants a head turning system. Obviously there are reviews about them blowing, overheating, etc. I've used my sub at a setting of - 4 on my head unit, and it is still unreal. Don't doubt Boss, it's worth it.
