AMP-80 is a factory Hyundai Mobis amplifier fitted in Kia and Hyundai cars. It is found in Kia Carens, Sportage and Sorento, as well as Hyundai i40, ix35 and Veloster models from around 2010–2018.
The surest way to identify it is the rating label on the casing. Common part numbers are AMP-80SLE: 96370-3W300, 96370-3U700, 963703Z101 and AMP-80RPE: 96370-A4100, 963703Z150.
When making an enquiry, send a photo of the label with the part number if you are not sure of the model. You send the removed module to the workshop; we check it and confirm the scope of work.
