one of my friends is selling a jl audio 8" sub and 2 pioneer 6x9's in a custom box for $30. i dont know which model sub it is but its the cheapest model i know and the only problem with it is the cone is mashed in. so is it worth 30 bucks? and hes selling a pioneer amp for $20 what about it . its a very small amp so it can be more than 500 watts maybe idk thanks trevor
