oh sorry, i must have skiped over that part. still sounds like the easyest and best way ive seen in this post so far . Also it can be done with some minor modifacations. DK

Also, you can use a holly electric fuel pump, transmission oil cooler and a tank, and pump fluid through copper tubing that just sits between the heatsinks. A few notes here, that noone pays attention to. Don't use antifreeze!!!! If it leaks, your screwed. Denatured alcohol is the optimal coolant, because of three characteristics. 1. High Flashpoint 2. Non-conductivity 3. Quick evaporation.
Mark Liggett has such a setup in his truck, he'll tell you about it if you see him at a show.

Simple solution....go buy one of those Ice Coolers that plugs into your cigarette lighter. Remove the cooling device which is a 12 volt cooling unit. Blow air accross it and onto the amps and you now have air conditioned amps. Be sure to put some type of gortex filter between the amp and unit, to take the moisture out of the air, no condensation is good for an amp. Also, use a thermistat to turn the unit on only when the amps are hot enough to require it.

Joe, good idea, however, those systems use a peltier junction to remove heat. These work great only under direct contact with the heatsink, then you need yet another heatsink with a fan on the opposite side of the pelt.
It could be made to work though.

Those are the same type of thing I talked about earlier. I don't know if the two terms can be used interchangeably but from what I know they work the same, or are the same, I've just known them as TEC's.

Yeah, a peltier junction device is a TEC, you're referring to the same thing. Pretty fun stuff, especially when overclocking computers. If the fan dies, you're dead.

You don't need a heatsink with what I described.
1. You attach the copper tubing to the existing heat sink on the amp. 2. The transmission oil cooler eliminates the need for the heatsink and fan to cool, because that's what it does. Mark Liggett has the same thing on his nissan truck.

mount the amps on dry ice =) there won't be any condensation and it'll keep it cool as he| |. or just put blocks of the stuff on top of them. it turns straight into gas..

As mentioned, Peltier elements (the electrical cooling gizmo that sits in active 12V coolingboxes) and all other principles almost all have the problem of condensation. Do a search on overclocking processors and cooling, and you'll get all kind of descriptions on how to do it and the problems you run into. I can probably get my hands on heatsinks with tubing going through and 20 TO-3 size mountingholes (a kind of transistorhousing). They have been lying at a dumpstore for the last 10 years, so they are probably still there...
How about just dunkin' your amps in destilled water ? That's how a friend of mine conducted his amp-test : >1kWrms running for 24 hrs on a 1 ohm watersubmerged load of 4 parallel 4ohm 250W resistors. Just replace the water once in a while...cause the resin from the solderparts and other stuff will eventually disolve and mess up the cleanliness of the water.
