Q: QuestionWould this work amp wise with a CT200H? Basically a Prius. The AMP uses 30A fuses and I think that is the max that can be used w the Hybrid System, but I really do not know. Please help.

Asked 1 year ago by KitK.

• A:Answer If the maximum current draw is 30 amps, this would not work. There are two thirty amp fuses in the amplifier. The main amp before the battery should be 80 amps. Please work with Best Buy’s Geek Squad. They will verify the fit and assist you with any further questions.
