Stereo

Is one of the wires that run to the stereo connected to a relay by chance? I have an aftermarket radio in my '91 XJ and I notice that whenever I turn it on, I can hear a relay clicking.

The relay is located on the passager kick panel under the dash, right under the glove box. Thanks

Relay for a power antenna seems the most likely answer or possibly an external amplifier?

I could be. I did remove the deck and it seems that there is not an amplifier attached. I thought that there was due to the sound that the relay makes when the head unit is switched on. Weird.

Would it be safe to bypass the relay? Thanks for the reply!
