Qx2Gx

Hey all, this is my first post within the RX boards. I am in the process of purchasing a new vehicle within the next few months; lately I have been debating between a GX470 and an RX330/400h with no definitive decision as of yet (I am currently coming from a 2001 Infiniti Qx4). I have a question about the 400h...is it possible to throw in an aftermarket audio system? I am currently running a double din Pioneer AVIC-F90bt head unit (I would most likely purchase the double din bracket from the harrier and install it beneath the stock LCD screen...redundant, I know), pioneer 4-way speakers in my doors, an audiobahn monoblock amplifier, a 1.3 farad capacitor, and a 12" kicker solo-baric subwoofer. This type of setup takes a lot of juice and I was wondering if there are any specifics within the 400h that would make this setup inherently dangerous or impractical. This is a major selling point for me...as I would imagine there would be no difference to my current setup if I purchased a gas powered 330 or GX. Any input is appreciated. Thanks!
