Post Becker Grand Prix 1432 Aftermarket Amplifier

Hello! I've got a Becker BE1432 and I was wondering, is there any way I could use the radio without plugging the amplifier cable and not getting the E 2 error (which shows up when the amplifier cable is not connected), because I don't have one and I would like to use and aftermarket amplifier connected directly to a low level audio signal from the board? Thanks

You cannot separate the head unit and the tuner unit in the trunk. The head unit is only the tape deck and the pushbutton controls. The actual radio and audio generation circuitry is in the tuner unit in the trunk. The head unit will not work without the cable connected to the tuner unit.

I did more or less what you want to do by feeding the speaker output ports on the tuner unit into a line-level converter to feed into a power amp. Be aware that the sound quality is not great doing it this way, the tuner uses some weird equalization that boosts mids and attenuates treble/bass. If you run through an equalizer it may be ok, but I hit the trash with mine and went full aftermarket stereo and haven't looked back.
