i was wondering how you wire an amp cooling fan from the power wire for the amp? lets say you have a computer cooling muffin fan that draws 150mA @ 12VDC. what would you need to do to get it to blow but not blow up? the power wire has a 30amp fuse on it already (amp kit power wire that is powering the amp) thanks ~Ryan

You don't want to hook up peripherals like fans to the amp power wire. It has a ton of amps running through it, and you see that the fan only draws 15% of one amp. Use a 12 volt source, and fuse the fan wire with a 500 mA fuse. You can use the remote turn on wire with a relay, shown on the relay page here: https://www.the12volt.com/relays/page5.asp#rtol The fan will operate while the amp is on without the need for an additional switch.
