OK . I bought my fan today now I was wondering what size fuse would be good . It says on the fan that it is 0.16 amp and 1.9 watt . I was thinking of going with about a 1 amp fuse . Is this ok or do I need more/less ?

I try a quarter amp first. Then if it blows which it shouldn't go to a half amp.

hey ynot...

hooking a fan to your amps turn on and ground wires may cause some noise (like alternator whine). it happened to me... you're better off running a dedicated line and using a relay.

ramos again thanks for the info and MxRacerCam thank you for the heads up . I would have been really upset to hook every thing up and then had a whine . I got a relay but I am not sure if it will work . It has four terminals . Is that enough if I want to also hook a toggle switch to it ?

yeah, a standard four post automotive relay will work fine. if you're going to run a swith, put it inline from the power source to the relay, not from the relay to the fan. an easier way would be to ditch the switch and have the amp turn on be the switched power input (and thus the automatic switch) on the relay. doing it this way will have the fan come on automatically when the amp powers up, that way you won't forget to turn the fan on until after its gone into a thermal protection mode.

I was wondering if it would be to much to wire something so that u dont have to worry about turning it on and off just what i thought just since it doest take much power.

Sorry what I ment was to wire somthign off teh fuse panel.

set the fan so it blows air across the top, not air on it, you will notice the cooling difference. if possible, mount the amp verticle

It's not a problem to use the turn on lead. Just make sure you use a relay. Otherwise you run the risk of burning up the remote lead from the head unit. Although it may not seem like alot of current. Most remote leads are only rated for a few hundred milliamps. Which is not very much power at all.
