i'm sure none of you are from houghton lake but oh well. this *** clown tried to sell me a coustic 800D for $400. he said since it was class D it had unlimited amount of power output. he had nothing setup where the customer could listen too. i wanted to listen to some jl w6v2's. he agreed to pop a couple inside my box in my car too listen too. well i wasn't impressed. he then said my box wasn't right which was pretty close to JL specs. he said the port needs to be shorter for more bass. i said it's tuned to 30 hz. of course he didn't know what the hell i was talking about. he just guesses how long it should be. then when i told him i didn't want too spend $600 on those subs, and that i didn't like them, he got pissed and banned me from his store.
