Soundz Sm4.100 Powersport Amplifier. For an Indian challenger plug and play , it powers up and music can be heard but there is a crackling hash sound might be something as simple as a setting or connection problem as it was fully checked before being sent to the Indian dealership who fitted it from new in my indian challenger Ltd. , not wanting to investigate a replacement was sent , if you know a good electrical engineer to check it out it should be a great amp and the replacement was amazing.
