Nakamichi NQ623BDT car stereo
The Nakamichi NQ623BDT is a very well-equipped 1DIN car stereo designed for those who demand not only modern connectivity but, above all, control over the sound of their audio system. Compared to ordinary car radios, it offers a built-in DSP processor with advanced adjustment options, allowing reproduction to be tailored to the specific vehicle and the listener's personal preferences. Available features include Time Alignment, a 40-band equalizer, active crossover settings, phase adjustment and independent subwoofer control. With six high-voltage RCA outputs at 4 V, it also forms an ideal foundation for high-quality audio setups with external amplifiers.
Wireless connectivity is handled by modern Bluetooth 5.0, which enables convenient handsfree calls and wireless music streaming from a smartphone. The head unit can also be controlled via a mobile app, and it includes an input for an external microphone as well as support for steering wheel control. The front USB port not only plays music but also charges mobile devices with up to 1 A of current.
A major advantage of the NQ623BDT model is its support for a wide range of music formats including lossless FLAC, APE and WAV up to 24 bit / 96 kHz, allowing you to enjoy music in significantly higher quality than common compressed MP3 files. Support for WMA, AAC and M4A is also standard. The integrated amplifier delivers up to 4 × 50 W and the clear two-line VA-LCD display with multi-color backlighting enables easy operation and excellent readability in all lighting conditions. Thanks to its rich feature set, compact mounting depth and extensive tuning options, the Nakamichi NQ623BDT is an ideal choice for anyone looking to raise the sound quality in their car to a significantly higher level.

About the brand
The history of the Nakamichi brand goes back to 1948, when it was founded in Japan by Etsuro Nakamichi. His journey began with the establishment of the Nakamichi Research Corporation in Tokyo, focusing on sonar and magnet research and development solutions for leading brands, government institutions and universities. From the start the brand built on a scientific approach, deep understanding of sound and emphasis on technical precision. The key growth period came in 1972 when Takeshi Nakamichi joined the company and played a major role in developing the legendary audio products sold worldwide. Under his leadership, models such as the Nakamichi 1000, the world's first cassette deck, were created. By combining top-tier sound and timeless design, which the brand's chief engineer Kozo Kobayashi also contributed to, Nakamichi products became icons of their era. Nakamichi remains successful today, offering a portfolio of high-quality products for home and car audio that stand out for thoughtful construction, excellent workmanship and great sound for their price category.

| Car radio sizeCar radios are divided into 2 basic sizes, 1DIN car radios and 2DIN car radios . 1DIN size car radios - the exact dimensions including the metal frame where the car radio is inserted are 184 x 53 mm, the external dimensions of the branded 1DIN car radio are 188 x 59 mm. We know 2DIN car radios from newer vehicles, a classic example is the VW Golf IV with navigation. The dimensions of a 2DIN car radio without a metal frame are 180 x 101 mm, the external dimensions of a branded 2DIN car radio are 189 x 119 mm. | 1DIN |
| DisplayAdditional information about the display. Segment, LCD, multi-line, etc. | VA-LCD, 2 lines |
| CD driveCar radios with CD drive. Car radios that have an input slot for inserting a CD. | No |
| Integrated BluetoothBluetooth is a communication technology used for wireless connection between two or more electronic devices. A mobile phone, for example, can be connected to a car radio with built-in Bluetooth. Most car radios for 2017 and later can also wirelessly stream (play) music via Bluetooth -> A2DP function. | Yes, 5.0 with support for A2DP, HPP, HSP profiles |
| USB inputThe USB input of the car radio is used to connect a USB flash drive or smartphone. Today, playing music via USB is the most popular way to listen to music in the car. The USB input can be front (on the front panel of the car radio) or rear (on the back of the cable). | Yes, 5V / 1A |
| SD card accessModern branded car radios can play SDHC SD cards up to 32 GB, sometimes even 64 GB. The SD card slot is behind the front panel in most car radios. | No |
| Supported formats via USB inputList of all supported formats (MP3, AAC, Flac, DivX, etc.) that the car radio can play via USB input. | MP3, WMA, WAV, FLAC |
| Apple CarPlayApple CarPlay is a completely new option for connecting a smartphone to a car radio that has the Apple CarPlay function. The connection is only by cable, thanks to the high data flow. You click on the Apple CarPlay icon on the car radio screen and application icons appear on the car radio screen like on a smartphone, and you can continue to control everything using the car radio. It also works with voice control and Siri. | No |
| Android AutoGoogle's Android Auto is a completely new option for connecting a smartphone to a car radio that has the Android Auto function. The connection is only by cable, thanks to the high data flow. The Android OS requirement is at least version 5.0.

Voice control and GPS signal also works. | No |
| Car radio performanceThe performance of the car radio shown in maximum values. This is therefore the MAX value. The performance of the internal amplifier of the car radio. Today, the RMS power of a car radio ranges from 17 - 30 W RMS per channel. | 4 x 50 W |
| Number of RCA outputsRCA outputs , colloquially called "cinches", are used to connect an external amplifier or active subwoofer. Aftermarket car radios are usually equipped with 1 to 3 pairs of RCA outputs. FRONT, REAR and SUB are used. It also depends on how many volt outputs the car radio is equipped with. More basic models of car radios have 2V outputs, more expensive units have 4V and more. The higher the specified value, the less power demands are placed on the external amplifier and the sound quality increases. | 3 pairs |
| Output level on RCAAn important parameter if you are going to install an external amplifier. If you purchase a car radio with a basic value, i.e. 2V outputs, then greater demands will be placed on the power of the amplifier. As the value increases, e.g. 4V or 5V, the power of the external amplifier increases significantly, in layman's terms. A car radio with strong outputs therefore has the advantage that you do not pull so much power through the amplifier and thus achieve a better sound, as external amplifiers lose control at higher loads. | 4 V |
| Backlit buttonsColor options for the backlight of the car radio buttons. | Multicolor |
| External microphone included in the packageThe external microphone is connected from the back of the car radio to the input marked "MIC". For ideal sound quality during a phone call, we recommend placing the external microphone on the left "A" pillar at the point where the "A" pillar and the roof panel connect to each other. A very good position to place an external microphone is also near the central rear-view mirror. | No |
| Removable front panelPossibility to remove the entire front panel of the car radio by pressing the side button. A very effective weapon against car radio theft. We recommend not hiding the panel in the vehicle, but taking it with you. Alternatively, place the panel in a hidden place in the trunk, but not when leaving the car, but before parking. You never know when a thief might be watching you. | No |
