Just a thought:
I have:
a. car radio (2x25watt),
b. 2 speakers (25watt)
I buy:
2 speakers (500watt)
I need:
an amplifier (verstarker) (2x500watt)
I don´t need:
a new radio
--------
I have:
a. speed controler (10a@12v)
b. Motor (10a@12v)
I buy:
motor(750w)
I need:
an amplifier (verstarker) (bwz. 1000w)
I don´t need:
a new speed controler
--------
of course my watts, amps and volts are just guesses, but the question is will this work? is it possible to adapt a pkw verstarker for this purpose and use a smaller speed controler?
