Using car speakers in a cab

well.. the magnets aren't that large on them.. and I plan to put them in the traditional spot up by the marquee.. being an upright cab i'm not sure if proximity will be a problem or not..
how would I go about shielding anyhow?

Actually, you'd be surprised at how powerful those magnets can be. The best way to test is to turn on the TV or monitor you're going to use, then hold the speakers near it, at the same distance they will be in your cab.
I'm not really sure about shielding them. I think that a metal plate will stop some of the interference, but you'd probably have to experiment with it. ...maybe kryptonite? <g>

they don't have to be on do they? hehe.. would hate to buy the amp and etc to find out they won't work.. anyhow i'll hold them near my PC monitor and see what they do... hehe ;)

A thin piece of sheet steel makes an excellent magnetic sheild.
1. Don't the the magnet touch it. If it does it becomes sort of a magnetic amplifier.
2. Don't let anything electronic touch it. It'll short out. (Duh)
3. It doesn't have to be big. Just between the magnet and picture tube. If the speaker in in it's own boxed space, just line the box with the sheet steel.

No, they don't need to be on - it's the permanent magnets that cause the interference. You'll see as you move them around the monitor... looks phsycadelic!
