O.k :S. Since you know my car you know that I have 2 more amps behind the box running my mids and tweets in my front and rear doors and my 6x9's in the rear deck. And the sub is a DC 15 it is old school but do some reaserch before you get to shooting off there is a hyundai in the states that hit 150db with Lanzars just because they are not MA or what ever don't mean they are no good.
