Power per channel

The rated sound power produced by the radio amplifier for each audio channel.

Nominal is the highest average (rms) sound power at which the amplifier operates without overload and is able to operate for an unlimited time. This is the main indicator characterizing the overall sound volume of the radio; individual power surges can be much higher than the nominal value, but they are short-lived; here we are talking about a constant signal level. In addition, compatibility with specific speakers depends on this indicator: the rated power of the speaker system must be no lower than that of the amplifier, otherwise the speakers may be damaged at high volumes. However, the spread is not so great; there are radios with an output power of 40 W, 45 W, 50 W, 55 W, 60 W and more.

Optimal amplifier power settings depend on a number of factors, ranging from the number of channels to the personal preferences of listeners. Detailed information on this topic can be found in special sources; In short, we can say that the higher the power per channel, the louder the sound the radio can produce.

Built-in memory

The volume of the internal built-in memory of the car radio. The presence of built-in memory allows you to record content (music, video, etc.) directly to the device and play it without using any additional media such as optical discs or USB drives. For comparison: the volume of a file with a photo is up to several megabytes, the size of one song in MP3 rarely exceeds 15 MB, the volume of lossless music files is estimated at tens of megabytes, and movies in DVD quality start from 1 GB. But for now (as of 2021), the memory in car radios is significantly inferior to smartphones and tablets — the bulk has 32 GB or 64 GB. But there are 128 GB radio tape recorders.

RAM

The amount of RAM memory.

Many modern premium car radios, as well as regular models, are close in functionality to tablets or even laptops; this is especially true for models that carry a full-fledged Android operating system on board. Accordingly, information about such devices may also contain purely "computer" characteristics, such as the amount of random access memory (RAM). The more “RAM” ( 4 GB or even 6 GB) provided in the system (ceteris paribus), the better it works under intensive loads, the easier it is to cope with “heavy” tasks (for example, resource-intensive applications) and performing several tasks simultaneously.

At the same time, note that manufacturers of radio tape recorders, usually, equip their devices with a volume of RAM that is quite sufficient for solving basic tasks and working with built-in programs ( 2 GB or less). Therefore, quite often information about the amount of RAM is more marketing than practically significant — it is designed primarily to create an appropriate impression of the product. It makes sense to pay attention to this characteristic if you plan to run various additional programs on the device.

It is also worth noting that different software platforms have different requirements for RAM, and the characteristics of the processor (see below) also affect the overall performance. Therefore, only models w...ith similar processors and software can be compared with each other in terms of RAM.
