Review on 🚗 9 Inch Single Din Car Stereo with Carplay - Touch Screen MP5 Player with Bluetooth/FM/USB/AUX, Phone Mirror Link + Backup Camera by Matt Travers

Installation was easy following the wiring diagram on the back. If the subwoofer output doesn't work, go into the settings and increase the volume of the rear speakers with the equalizer and they work. If you see a blue screen, you connected the backup cable incorrectly. This will not turn on the subwoofer with the blue wire. I used the same switchable 12V source as the stereo to power the subwoofer. It sounds very nice when you adjust the equalizer.
