I am lookin at a 02 Scooby, I have a set of 6.5" type r components and was wondering if they would work in this or not? they're being run off a Memphis PR-300 amplifier seeing 150W, Also currently have a Alpine CDA-9835 and a Viper D1200.1 running 2 Cerwin Vega vmx-12.4 subs. Will all of thi go in the car no problem? Will the stock charging system handle this amp? I know that my Cavalier had no issue with it.
