Hach,

Why don't you run the amp off a separate battery instead of dicking around with this DC Voltage booster business ?

Mike.

Problem is we did not know booster was preset 18 volts output and amplifier can handle only 9 volts. That why it blow up amplifier. Clark told me more voltage supply to the amp will have clear and stronger sound!? Man and Dean just install at it and destroy the amps.
You mean we should have one extra battery to run amplifier?

Just by running two batteries you will get cleaner sound, if voltage drop is the problem for the amp. Moreover, if you run two separate battery then you can run higher voltage amps as well since they are not tied to the 7.2v or 7.4v battery with the MFU. 

The input power can be completely separate for the amp. You can also do this for the smoker. We use TARR smoker and I have run it separately with a 3S lipo (11.1v).

I will try it
