How to replace Volvo Radio and keep factory Amplifier?
Volvo Premium Sound or High Performance Sound system includes radio tuner, speakers, subwoofer and 40W x4 amplifier (mounted behind the radio) or 50Wx4 (mounted under passenger seat). Replacing the factory Radio and keeping the rest of the system is not as easy as placing an aftermarket unit in its place. Your installer may suggest the entire audio system must be rewired, but thanks to the ARH-VOL it is now possible to replace the SC-xxx (e.g. SC-816) and HU-xxx (e.g. HU-850) radios in Volvo 940, C70, V60, S40, S70, S80, V70, XC70 and retain amplifier and the rest of the system including speakers, Subwoofer.
The ARH-VOL eliminates the following radio replacement/Amp retention issues:
1. No sound coming from main speakers
2. Only main speakers play
3. Subwoofer does not play.
