Hi. So what have two 2x2 5watts road pro speakers. After finally deciding, I would like to mount them facing down under my headrest.

I know there might be better places.

The headrest will have to stay up which it always is. There is a crevice on the bottom of the head rest between the 2 poles.

My question is.... do I need to worry about the speaker magnets being about 3 inches from my neck/head????

The speakers are enclosed with the hard plastic case( as other communication speakers).

Thank you. I'll try to edit and add a photo.

There is no health issue with body parts being near a static magnetic field, unless you have metal objects embedded in your body for some reason.

The only potential health risk is with alternating electromagnetic fields that result in energy being absorbed by body tissues.

Also, speaker magnets generally form a closed magnetic loop that results in minimal stray magnetism.

It's not something you should be worried about.

This is in a vehicle? Unless you duct tape your head firmly to the headrest, it won't be a static field. Probably wont kill you but, why would you want to risk it? Read up on transcranial magnetic stimulation.

Here is my pic. I am facing the driver seat. My hand is holding up where the speaker would go.

Those are small, the magnetism probably won't kill you as I said, but what if in a collision they dislodge and wedge between your spine and the seat?

Which is done with high-frequency alternating magnetic fields, not static fields. Do you even science, bro?

Unless you're talking magnets orders of magnitude stronger than those found in an MRI, normal body movement will not induce currents in the body sufficient to have any detectable effect whatsoever.

Yep I really do science. The OP said he was going to attach speakers to his headrest. I pictured some oversized communications speakers with powerful neodymium magnets, not those tiny ones. My point is that unlike some headphones firmly planted on your head, mounting them on the headrest by your head is NOT a static field because your head will be moving while the vehicle is in motion. Picture your head as an armature in a fixed stator field.

Really at this point the danger is mechanical one in event of a crash.

I'm going to Velcro them then rope a strap around them to the poles.

So the magnets seem small enough to not pose a dangers etc?

Probably, no guarantees in life! YMMV ,

The proposed installation is kind of dumb. The speakers are firing into the seat and are going to be muffled. You'd be better off putting them on the dash or somewhere they can point in the general direction of your ears.

Well. They sound good to me. I do t need them for the passenger. Maybe one day I will.

Thank you all for your input. When I finish I will put up pictures.

NOT dumb at all. Nice speaker installation, Sir.

Nice for those 'passengers' who do not like radios.
