Ideally, the stands should lift the speakers to roughly ear level of a sitting person. This is important because it aligns the subwoofers and tweeters relative to the ear and achieves the best balance of sound. The high frequencies are often missed when speakers are placed too high or too low. Speakers placed on a shelf or table often cause the surface to vibrate, thus distorting bass. These speaker stands isolate the speaker's vibrations from the floor, allowing you to hear the bass from the speaker and not the vibrations from a shelf, table or floor. Speakers come in various sizes and shapes, so the height of your speaker stands is dependent on your unique speakers. For this project, we give you the dimensions suited for the speakers shown in the photo, but you can alter the design to fit your individual needs.
Conduction is heat transferred across solid surfaces- think touching a hot stove. It’s also how heat gets out of your van in the winter. The heat inside your van is conducted through the solid surface of your walls and ceiling. Insulating the inside of your van will help prevent heat loss through conduction during the winter, and will also stop your van from conducting the sun’s heat inside during the summer.
I’ll throw this suggestion out to you too – while a warm sleeping bag would be a good start, maybe a couple sheets of plywood to put over the truck bed with a tarp over that would provide you some extra protection from rain/snow and also trap in some body heat. You wouldn’t have to make them permanent and could just slide the wood into the bed when not sleeping under it. A cheap bivy as Ryan suggested would also be a good consideration and a quality sleeping pad to provide some warm rating and comfort from the truck bed.
I save all my back issues of The Family Handyman magazine and love the projects and repair tips. The trouble is, I’m not always ready to do the project when the issue arrives. To make my favorite articles easy to find at a later date, I put a stick-on label on the cover and then add notes for easy reference when the time comes to do the job. — Willie Schreiber.
