Sorry can't help with the power supply and speaker wire as don't have an extra but if you need a speaker look at www.turnswitch.com for a replacement. When I put in my original am/fm truck radio I purchased a speaker from them. VERY happy with the sound, look and fit. Uses the original speaker mount (hopefully you have that) and is a nice alternative to having a speaker re-coned in my opinion. Good luck with your install.

Just want to add it is fully compatible with regards to the ohms resistance of an original radio.
