I have a 96 Integra and before that a 90 CRX and both using a Kenwood Head Unit. In the CRX which was an OVEN in the interior with it being black and all that glass, and even with taking the Empeg in and out of the car for work, anything more than about 30 minutes and I'd be tripping the alarm. So I atttached a fan and this helped... but not much. So when I got the Integra, I had to mount the Empeg ABOVE the head unit and on the CRX it was below. I thought this would improve airflow but the same problem returned. Well... I am a Mechanical engineer and have access to a laser, so I had them cut me two fan cutouts to the left and right of the middle fan and centered in the plate. I then bought a hard drive cooler set up that is supposed to mount to a 5.25" hard drive and it has 2 BIG fans and a heat sink... well, with a little maneuvering, this will go in there across both hard drives and the cover closes. It is loud, yes, but it doesn't bother me. At work, it dropped the temperature about 23F and actually is more efficient than the open air setup (I did some tests). In the car, the warmest I've gotten is 47C and that was on a near 90F degree day with no AC on and an hour drive.... but it hit that temp quickly and stayed there. This is just my solution... I've got 80GB with like 19,000 songs on it and I do not use the radio because it's horrible around here so I had to have a solution that kept me with music all the time no matter what weather
