you could try a bucket of ice........... Other then fans there isn't really a good way to cool amp. As long as the air going across it is cooler then the amp it will help. You can also try to reduce the heat the amps put off by lowering the impedence that they are running, as well as maybe turning the gains down.

If the heatsinks are hot, the design is working beautifully. If the amp is shutting down, then it is time for a change (like ditching the plexi). Yeah, it looks cool for shows, but trunks are basically hot places and not a wonderful environment for electronics that produce a lot of heat.

Have an innovative idea for you to consider. It's an electronic heater/chiller that happens to power off a 12 volt DC power supply.
Basically, it's called a Peltier device, used by Coleman portable coolers, (and others like it) that can cool or heat, (depending on polarity of wires) fed to this device and you need a fan to blow over it to create the chiller effect. This unit with a very small fan, can chill a 2 cf container to about 45 degrees F., in about 1-2 hours. The higher the fan velosity, the faster it will cool.

One thing though, this chiller needs to be in a separate chamber then amplifiers as it does form condensation as it chills. You will need something to contain and remove the water as it accumulates. A good size sponge will do.
