Used to install a new radio in a car that has an original fit amplifier that takes a pre-amplified audio feed.

This interface converts the high level audio output of a new head unit to a low level pre-amplified signal which will work with an amplifier.
4 adjustable channels for optimum audio quality, it has a built in ground loop isolator and filters to get the best sound from the amplifier.

This lead has 8 way ISO connectors at both ends so if it is used on a car with different connectors (such as Saab, Nissan, Mazda) then you need to use the car specific lead as well. This might be a steering control or a standard ISO audio cable.

Can be used with car specific ISO leads for Nissan Bose, Mazda Bose, Honda Premium sound, Saab Bose and some earlier Landrover Harman/Kardon (not fibre optic versions) or any car with OEM low level pre-amplifier signals from the original radio

Active speakers 4 channel adjustable.

Always ensure that you connect the remote turn on wire from the new aftermarket radio to the Blue / white wire on this interface
