How can I make use of the REMote lead on my car amplifier to turn on/off other devices? Answered

Hi guys,

My amplifier is running super hot (JBL passively cooled amp) and it always cuts my sound when it overheats.

I've managed to attach a PC fan and it's providing decent cooling for the amp. It currently has to be turned on manually using a rocker switch (wired to the front, underneath my seat) whenever I get into the car.

I know that the remote lead receives a electric signal when my engine is started and that switches on my amplifier and off when the engine's off.

What kind of switch can I get (hopefully off eBay) that will turn the PC fan on and of when it receives the signals from the remote line?

Many thanks!

You'd do better to stop it overheating; too much load / volume.
I.e. get another amp' or turn it down a bit.

Why bother ? Just put a thermal switch on the amplifier, and let it turn on the fan when it gets too hot.
