Radio Heat Problem

[lopeha]

I'm installing a Kenwood KRC-235 into a Cycle Sound enclosure. While doing an ops check I noticed the back of the radio was very hot. The unit will be inside a molded plastic enclosure with foam on top/bottom of case. Two questions - 1) Is the heat normal for this unit? 2) What would be good to put between the unit & the foam to prevent a flame up while going down the road? Thanks in advacne for the help, Andy.

All head units get hot. Most get really hot.

Road Glide or Electra Glide? If you're really worried about the heat, cut the bottom out of the enclosure and ventilate the top. The fairing itself if pretty water resistant so you shouldn't have to worry about water getting in the back of the head.

Actually on a '83 Gold Wing with a Vetter fairing. A friend is a fireman & I may try to get a piece of one of his old jackets to act as a buffer.

I really wouldn't be too concerned. Ventilate the container if you're really worried. It still should be fairly waterproof. Adding insulation is the last thing you want to do as it will trap even more heat nd possibly lead to the HU overheating.
