Attenuator

[chuka]

I was trying to install bluetooth hands free in my car.
The unit goes between the radio and the amplifier.
The problem is that the Bluetooth unit has 4db amp build in, two amp in serious causes pop sound and I can't control the volume.

I'm looking for low cost 4 channel attenuator with control.
By default it will not be active but when the Bluetooth hands free is active it will send a "mute signal" that will activate the attenuator.

Help will be appreciated.

Are you sure? Most Bluetooth units connect to the radio's remote input (yellow wire?), because otherwise they could not be used, when the amplifier is integrated into the radio.

What happened to the radio's attenuator?
