- OEM 12V remote turn on signal thru relay for voltage compatibility to all aftermarket amplifiers

Line output converters can be added to the harness by custom order at extra cost.

This harness function is to completely replace the OEM amp, it cannot be used to complement the OEM amp with an aftermarket amp (as in, installing a sub/amp while keeping the OEM amp). The harness also cannot be modified in any way to drive the main power or ground of any aftermarket amplifier. Amplifier main power and ground connections are still required to be made directly to the battery.
wondering if the package will work for us without amp. I have 2009 323i which doesn't have amp. HU powers the speakers but in process of upgrading to add 6 channel amp.
