any suggestions on why the HU is keeping no memory and ive got 0 sound from the rear speakers?

 

Yellow on the Pioneer hdu is the battery lead and should go to the orange in the car, which is hot-at-all-times. The red on the Pioneer hdu should go to switched power (hot-in-acc/run) which is usually yellow in the thirdgen cars. As for the rear speakers, check for a short or blown speakers. Disconnect the rear speaker leads from the car and connect directly from hdu to known good speaker. If you get sound, try the rear speakers directly to the hdu. If they work, then you need to run new wires to the back. Let me know if you need any more help
