Using the built in tige cooler, fill it with ice. Run a fan that would suck air out of it, and up into the compartment, since the ice and the cooler (full of soda right
) will be very cool, right around 32, the compartment should have no problem staying cool with that type of air blowing over the amps.
The problem I'm having, is how Can I pull air out of the cooler, but still keep it water tight so that water isn't leaking all over and the ice makes it past 30 min in the +110 F bako days.
Just an idea, but I'm hoping just the air blowing on the amps will be ok. I do know that when I leave the compartments cracked while driving it promots enough air that the amp is fine, just wonder how it will be with 6 ppi amps, as opposed to just one and two regular amps.

I wondered if and when this one would come up!
I will relate a story:
Years ago, as a poor college student, I had to get in my old '65 ford truck to go to a wedding. 100+ degrees, no AC, and a wool suit! I took a length of pool vac hose I "borrowed" and coiled it in an ice chest. Filled it with ice, duct taped one end of the hose out the window to the rear-view mirror, and the other end aimed at me. No fan, but highway speeds provided the necessary blow. It worked real good for about an hour going down the road, until I noticed a reduction in flow, and a gurgling sound. Some of you might quickly grasp what had happened....
Condensation in the hose had settled down at the bottom of the coil. Hah! Yeah, I made it to the wedding almost comfortable, but when I go home, I poured about a half-gallon of water out of the hose.
Bottom line, we can over-engineer, and yeah, it is fun in a redneck way... but we have to consider whatever other issues might come up...
On that note, I designed a cooling system for a sailboat I had about 10 years ago...
1 automotive heater core
1 livewell pump or
1 large 12 volt fan
1 good length of garden hose
1 weight to sink the hose
1 drip pan under the heater core
What it did:
Suck cold water off of the bottom, while at anchor and pump it through the heater core. Despite pulling from the bottom, head pressure doesn't start until the water surface, so it was easy to get flow. The fan blows over the core and the core chills the air. This was not an evap cooler, as the lake water was never introduced to the air/environment. Instead, there was condensation on the core, hence the drip pan. It was not perfect, certainly nowhere near the cooling power of a compressor-driven unit, but it worked!
Now if you guys could figure out how to run on plane and keep the garden hose near the botom...
