they finished talking about water cooling tubes or something like that...
so if someone could tell how exactly i could add 1 fan o 2 i dont know... to my amp that is in the back of the rear seat of my mx-3 i would appreciate it... thanxz!
You have to be a little careful when doing this. If your remote wire is from your headunit then it probly can only output 250mA, 40mm fans take 100mA a piece. I origionally hooked my fans to the remote, but the head unit was straining to put out enough power to that wire and a ton of noise spoiled my music. It's better to use the remote wire to trigger a relay, which will then turn on both your amp and the fans.the power you'll get from the remote turn on wire
It would be nice to know the exact setup. Unless the amp is enclosed it should be able to self cool itself. Esspecially if it's a 2ohm stable amp running at 4ohms (or similar situation).to my amp that is in the back of the rear seat of my mx-3
Actually, since we're dealing with such small current we can cheat a little.lakersfan1 wrote:You'll need a Bosch style relay and a relay wire harness (check partsexpress.com). Use the remote turn-on wire from the headunit to the turn on wire of the Bosch relay. Wire up a regular power output to the relay's main power. Wire the relay output to a couple 12 volt computer fans.
Exactly. Splice into the power wire of the headunit (yellow wire). If it's an aftermarket HU then you can put the splice right into the wire adapter. ((note: this is just for the remote line.. the actually power for the amp should be it's own system using a dedicated wire which should be fused 6in from the battery))jorgesamaniego3 wrote: -how i get the 12V cable?

If you are tapping the HU powerline, then it's already fused, you don't need to do anything. One fuse is enough.-I put a fuse between the star of the 12 volt cable and the relay, another fuse for each fan and another fuse before reaching the amplifier?
The remote line should be 18-22g (roughly). It isn't running much power, so it can be small.and what kind of cable should I use for this kind of conections... its cause i dont want to see my car in fire![]()
