check the plug connectors are the right ones for the radio maybe you need to fit more earths to the connectors

My specker was working fine then the am went to on protection mode and backs power mode but my specker doesnt work but on when my volume is low

go on control pannel-sound and speaker-there you can seet the speaker volume according your requirement

Was it working before?
If so, (a) fade control is not in the center or (b) Unit or speaker is broken
If it never worked, then check wiring

I also bought one and it came with no instructions either.

Should be pretty simple but if you want to control the On/Off of it by the head unit you will need to use a relay,

You haven't reinstalled the drivers for your sound device. If it's a Dell, you'll either need the Blue/Gray CD that came with the computer labeled "Device Drivers", or go to support.dell.com enter your service tag #, and select "Drivers", and download drivers for sound.
