So im in the army and the other day I was down in the motor pool going through some conex's and was able to get my hands on a pa system. So need some help hooking it up. I have got it to work but when I hook it up it doesn't turn off when I turn the truck off. Where do I need to hook the Pa system power cable up to so it will cut off when the truck does. Also the speaker I found doesn't have a mount how can I attach it.

 

You can wire it to like the radio or something that turns on when you turn the key. What does the PA look like? Itll give me a better idea so we can figure out how you can mount it.

 

There should be a remote power wire or something similar to that in your radios wiring harness. That is what I (and others) use in order to get amps to turn on/off with the truck/radio.

 

The box is about 2.5"Hx8"L the speaker is like a 6"x6" square brick

 

But is there like a screw coming out of the back of it or a hole in the back of it for a screw? Thats why it would be nice to have a photo

 

The box has a mount but the speaker has holes in the side the a bolt would go into
