Ok you wont believe this i just wanted to see what you guys would think,The obvious right.My cousin bought the md 500.2 because the dealer here in ontario is pushing them out of the shop like hot cakes and says they are hot ****.Wrong my cousin is on his third amp right as we speak and still has engine noice for some reason that no other amps make.Get this to make this all come to gether my buddy has the db testing program for his pc and we went over with his mini van with 4-10" PPI subs in a sealed 7.5 cu. ft wedge box in the back and tried out his md 500.2 first and the best he hit was 142.1 db's witch is pretty good for a sealed box i guess.Then it was time to try my sony class d amp witch i paid half that my cousin did because the dealer rips off anybody he likes,we used all the same stuff but the sony and it hit 142.8 db's.My cheasy ass sony beat mmats and since alot of people around town are gonna be running the mmats md 500.2 at the comps i'm gonna beat the sorry @ss with my cheap sony.Pretty funny stuff to me but not my cousin who is pissed.belive it or not this aint no BS boys.Later
