Review on 🚘 Soundstream VR-623B Bluetooth Car CD DVD Receiver with 6.2 Inch Touchscreen, High Resolution TFT LCD, Hands-Free Calls, Audio Streaming, USB, AUX, SD Card Inputs, LED RGB Colors, AM/FM Radio Stereo by Gopal Baltimore

Great product! Amazing price! The only downside is the 300w radio amp it puts out. If you connect more than four speakers with the built-in equalizer and LOUDNESS ON button without amplifier upgrades, the system will mute all sound. (Built-in safety feature so your deck doesn't burn) None of the speakers make any sound. You will need to reconnect your speakers to reset your Soundstream VR-623B in order for your audio to work again. Set the equalizer to your liking and leave the LOUDNESS selection off! I recommend getting a good separate crossover for any of your upgraded amps that you install. Use the Soundstream VR-623B with built-in EQ, crossovers and additional amps to find the sound you're looking for. Any adjustment made with the LOUDNESS button on the Soundstream VR-623B will mute any sound coming into your speakers. In this case, restore the speaker connection to reset the Soundstream VR-623B. Do not use the LOUDNESS button. Leave! Everything will be fine. It's still a good 300W audio player for the money. I recommend buying an expensive unit and spending the extra money to avoid this headache on any cheap aftermarket radio. You get what you pay for :)
