[THUNDERBIRD 10+ year member]

i have a hifonics 605bx amp and it gets hot and in my new setup i want to be able to fan cool it. how would i go about doing that, i am think a computer fan or some of those stinger ones, and using a relay to turn them on off of my remote wire. any instructions on how to so this would be great

i am gonna have an open back to the amp rack so if i just point a fan at it should that work?

get a relay, wire the fans to it, some computer fans would do nicely, maybe even a blower fan

Can someone explain what a relay is and where to get one. Also, Can you just cut your remote wire and splice the fan wire into it? Will that work ok??

Let me know, i am in need of a fan also for my kenwood amp.

a relay is like a switch, yeah i guess u could splice into it for a fan but use a relay if u have more than 2 amps because it does something with the draw of the power. someone else explain this better for me. u can get then at the autostore, radishak if u want to get riped off

the remote wires dosent put out enough power to use on alot of stuff

a relay, has a 12v input direct from the battery, and a ground

then you hook the remote wire to it to tell the relay when to send out power it gets from the battery,

something like that

The relays people typically use for this type of application (I have one for remote accessory activation myself as there are two amps, two 20" blue neon lights and one 12" blacklight that turn on and off with my head unit) are like this.

The relay needs its own source of power and ground (using two of the four terminals found on the end of the relay). Then one terminal will be for the trigger input or that which activates it....in this case the remote accessory activation output from your head unit. The last terminal will be the relay's output which activates once triggered by the aforementioned input. This last terminal will be where your accessories (amps, fans, etc) connect. Instructions on which terminal is which will be included in the package or sometimes printed on the back of the package.

I run my amp at it's full potential right, so after 30 minutes it gets too hot and shuts on and off from the thermal protector. It has no fan, so if i did put like a computer fan on it would i need to cut a hole in the amps covering, or would just running the fans air over the outside of it be ok? I know that it's not going to stop the problem, it would be much like control burning a house, just spraying the flames that try to catch the trees in the yard on fire and not the source of the flames. The amp has a heavy metal outer case, and im not sure if any of the small electronic fans i've got can fit inside it completley, so would i need to whip out a torch to cut an outline for this fan? Or could i just take off the top of the amp which would allow it to cool off much faster by itself?

Your amp has to have some type of fan I'd think, or a heatsink of some sort. Otherwise it would not take long for it to shut off, meaning a lot more quickly than 30 minutes.

If it is shutting down then you are either asking more of it than was meant to provide or the mounting location has inadequate ventilation. A fan can aid with the second one but won't have much effect on the first.
