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 |
| 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 |
| 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 |
| CD driveCar radios with CD drive. Car radios that have an input slot for inserting a CD. | No |

| DVD driveDVD ("Digital Versatile Disc" or "Digital Video Disc") is a digital optical data carrier format that can contain movies or various other data. Car radios with a DVD drive can also play classic CD discs, and the car radio always has a slot for only one disc, the CD drive and the DVD drive are always in one. | 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 |
| Audio Streaming via BluetoothA2DP (Advanced Audio Distribution Profile) is a Bluetooth profile that enables the wireless transmission of stereo audio from an A2DP source, typically a mobile phone or computer, to an A2DP receiver (car radio). These devices usually also support the AVRCP profile. | Yes |

| 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 |
| 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. | 2 pairs (4 pcs) |
| 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 pcs |
