I have 2 12" Audiobahns and my amp Bazooka 700w it is at half power and 6 bass leve it has 12 bass level and my bass at RF cd/mp3 is -3 and it hits like crazy. My trunk does rattle badly i need dynamat so bad. Even my bumper ratles. I recently put he power at amp to full and bass at amp to 12 and turned the volume to 10 and my all family was yelling at me because it was shaking everything upstairs. I was in garage. If you want great system go with Audiobahns.
I got this one for sale if is anyone intrested.
It is design to close the trunk for bonnevilles.
