thx1138 Posted May 27, 2010 Report Share Posted May 27, 2010 Hello, long time browser of the forums but first time signing up. I have a new amp and I will be replacing the top face plate with plexi-glass so I can mount one or two 30-50mm pc fans to keep it cool during the upcoming summer months. On my last amp I powered the fan from the remote wire but I'm not even sure how much volts it was outputting. All the pc fans are 12v. So what I'm asking is if anyone knows of a general 12v power source I can tap into on the amp that will only supply power to the fan when the amp is on, i.e. the 12v power cord from the battery wouldn't work because it would constantly be on. Thanks. Quote Link to comment Share on other sites More sharing options...

thx1138 Posted May 27, 2010 Author Report Share Posted May 27, 2010 What kind of relay? Quote Link to comment Share on other sites More sharing options...
darthballsy1 Posted May 27, 2010 Report Share Posted May 27, 2010 A switch maybe so when you turn on the amp you can flip the switch and the fans come on.

Yeah but if I were to go through that much trouble couldn't I just do it like I did before and power the positive of the fan with the remote wire? Does anyone know offhand what voltage comes from the remote wire or if I should even be powering it off of that? Quote Link to comment Share on other sites More sharing options...
EricM9104 Posted May 28, 2010 Report Share Posted May 28, 2010 Remote wire doesn't even put out an amp of current, just a few hundred milliamps. Wiring it that way will put severe strain on the deck. Don't be stupid and wire it right. Switch going to the battery and fans (fuse it of course) Quote 2015 Honda Civic LX 4dr | 24k miles Stock H/U and mids/highs Power Acoustik GW3-12" D2 Sub HiFonics BXX1200.1D @ 1ohm Random 2.5^3' dual ported box NVX LOC Stinger wiring throughout 1977 Chevy SWB Cammed 350 Dual exhaust Cheap Wish stereo Link to comment Share on other sites More sharing options...
J-Lane Posted May 28, 2010 Report Share Posted May 28, 2010 wire in a relay and use the 12+ lead from the battery This would be the easiest way to go. Just use the remote wire to switch on the relay and run your amps and fans off the relay. Then they will turn on with your system. Quote Link to comment Share on other sites More sharing options...

Neo_frog Posted May 28, 2010 Report Share Posted May 28, 2010 They said it all. A relay is your best bet. In fact, you could use a relay where the hot wire is from a constant source, the switched wire is the head unit remote, and the output goes to the amp. This would save you from having to run extra wires to the back and also allow you to run the fan off your remote wire at the amp without worrying about current draw since it's minimal anyways.

bassl0va Posted May 28, 2010 Report Share Posted May 28, 2010 If you want even lees strain, use a solid state relay, electromechanical draw probably the same amount as a fan!
