Hi,

This radio/stereo system does not have aux inputs it only has a 16 pin plug on the back and the antenna etc but not aux output connectors for an external sub woofer.
You will need to get a separate amplifier, and then wire this into it to have a sub speaker.

Also if you remove the radio you must also connect a scan tool to get the radio part number from it, as you will need to enter it back into to get it to work again.

Let me kow if you need more information.

Thanks

Jason

The door chime is played over the speaker. I had the same issue the speaker was junk. The circuit resistance was correct but no tunes. Replaced the speaker with one from the junk yard and sounds great all the time.
