I...I don't know what you're asking? There's a 12v source below the driver knee bolster?

umm... if you have an aftermarket amp in the trunk of the car, you have a 12v wire for the amp that you ran already. wire up a relay triggered off the remote amp turn on wire and you're good.

I can't run the fans from the amp's power.It has too high amperage for the little fan cables....Trust me,they will burn up in seconds

Do you know how basic electrical circuits work?

Do you know how not to be a sarcastic pr1ck and actually be helpfull?To satisfy your curiosity i know how basic and advanced circuits work.Saw one or two in my computer's engineer degree!For testing a set of 6 leds with the same wires as the fans in question,were connecting to a small 3.6v 2.5ah battery.Cables light up in fire.Anything else i can help you with??

Just do a web search on "how to wire up a PC 12volt fan in a car" since that seems like what your trying to do.

What you need is lower voltage, not lower amperage. 12v is probably too much and thats why your fans will burn up.

This is simply not true.

Rev was not being a prick. That was a very valid question. See above.

PC fans are actually 12 volts. They will actually be just fine running directly off the car's charging system. The OP is just not understanding basic DC theory.


umm... if you have an aftermarket amp in the trunk of the car, you have a 12v wire for the amp that you ran already. wire up a relay triggered off the remote amp turn on wire and you're good.

OP, do this. Exactly this, with an in-line 5A fuse for your fans. You'll be good to go.
