im building a box to keep my amps in and i was worried about heat so i picked up like 9 old pc's (bulky trash ahhh i love it) and took the fans out. i want to run them beucase they all run on 12 volts but all 9 of em combined has a current draw of about 2 amps.(around .3 amps each) so how would i hook them all up? i.e. fuses and how to lower the current down from the car.
