The radios below are highly suitable for the Porsche 928.
They have the right specifications for use with our restomod speaker upgrade
- Blaupunkt Bremen SQR 46
- Blaupunkt Frankfurt RCM 82
- Blaupunkt Hamburg SQM 23
- Blaupunkt Skagen 400
These models combine modern audio technology and Bluetooth with a design that better suits the classic dashboard of the Porsche 928 than a modern standard car radio.
Important features:
Pre-amp out means that all your sound settings (equalizer and volume) are also sent to the power amplifier or subwoofer. The pre-amp out power on these radios is 4V, which also keeps the sound clear. On cheaper radios, this is only 1.5V. The original power amplifier in the 928 requires 4V and has an output power of 25W.
With Bluetooth you can connect to your phone for music and calls. 5.0 is, of course, much faster than 2.1
A separate microphone is important because you can mount it by the sun visor for better reception.
Voice assistant is very useful for calling instructions or entering navigation
