Review on 🔊 Wireless Bluetooth 5.0 Stereo Amplifier System - 2x300 Watt 2 Channel Sound Power Audio Receiver with USB AUX SD Card, FM Radio for Home Speakers, Mini Car Audio Surround Subwoofer by MakerHawk by Robert Hunter

My old 1967 Sapphire Beetle AM radio's volume control died. I wanted to keep the old radio in the dash to keep my stock look. I took out the dead volume potentiometer, the lightbulb in the radio and all the old AM electronics. I left the tuning mechanism intact, including the knob, pin, and mechanical preset switches. This circuit board fits perfectly where the old volume knob used to be. I cut a D-shank out of an old pot and attached it to this board's split knurled shank. An old ballpoint pen is perfect for this. Replaced an old 2 watt incandescent bulb with an LED and resistor, replaced the old single speaker with two 50 watt 4 inch/4 ohm stereo speakers that fit perfectly in the old single speaker hidden in the dash. I put everything back in place and now have a Bluetooth radio in the normal radio instead of the old AM radio. Nothing but stock. I can listen to stored music, music/radio apps and navigate from my iPhone. Everything still looks like a skeleton. The volume on/off switch works just like the original. One caveat: the volume knob on this board has an on/off click on the far left, but it doesn't turn off the bluetooth receiver portion of the board; It just turns off the amp. Install it on a power source that is turned on by the ignition, otherwise it will drain the battery.
