I have an adapter between the radio my simple blue point radio works without any problems just with the Alpine can not make the adapter also because the radio no connection for it no standard plug.I have a box sometimes simply so jammed and the radio turned to full pulle but it was very quiet Seeing Hardly audible. Who can help you maybe need an amplifier for Alpine ?Does anyone have experience with it?
