I have mounted two amps to the right of the spare wheel. I'll be covering my two amps so they seem hidin(under the carpet). I know they get hot and heat will affect them. So i'll want to instal 4-5 pc cooling fans. I know where i want to mount them but my question is how do i power them up? I know i can connect them to any 12volt calbe but i don't want them to be on every time i turn my key to Acc. I would like to power them up only when i turn onmy headunit. Is there a wy i can connect some sort of reley to tell them to turn on when i turn on my headunit. Maybe use the same calbe that turns on my amps to turn on my cooling fans? Please anyone help.

 

well cooling won't be a problem unless u got ur system is on for a long time (bout 4-5 hours continuosly.) but if u must install fans i would suggest hooking them up to a relay. u need to ground the relay, put a constant power input and then use the power from the remote wire coming out of the deck (usually the blue w/white wire) for the switch power input. that way the fans will turn on when ur deck powers on and turn off when u shut ur deck off or turn ur car off. hope this helps.

 

Yeah that's what i want to do. No where can i get a reley and what type of reley should i use? Maybe someone can get me a link.

 

an automotive relay is fine. you can fine them at any autoparts store

 

check wal-mart, kragens, pep-boys, or if all else fails radio shack. make sure u get the one wif four contact points not the five contact point one tho.

 

get a SPDT relay. take your remote wire from the bakk of your headunit... use a female terminal, hook it to 85. take another wire, ground one end somewhere to your car nearby if possible and connect the other end to 86. run or find a wire that has 12v constant and connect that to 30. then connect all the + wires from your fans into 87. leave 87a empty.

youll see the numbers on the relay once you get it. this setup will do exactly what you need.

 

Yo thanks man i did just like you said and it works like a charm. Thank you

 

no problem. glad i could help.
