Car subwoofer kit

This material is for those who like to make electronic devices for their car themselves, or want to join a large detachment of such electronic motorists. We are talking about equipping the car with a very decent amplifier for the subwoofer, which allows you to develop power up to 200 watts.

In addition to the excellent performance of the amplifier, you will get a great opportunity to practice assembling electronic devices of average complexity, soldering, as well as designing and assembling a case for your device. The fact is that the set of blocks for assembling the proposed amplifier includes three devices:

  • NM2012M low-pass amplifier itself
  • NM0103 low-pass filter, and
  • NM0605 car amplifier power supply

Fig.1

All of these modules are kits for assembly and include printed circuit boards and sets of necessary electronic components that need to be soldered onto the boards. This format reduces the cost of modules. Additional savings are also obtained because the listed kits are offered as a kit, the total cost of which is lower than the sum of the costs of the modules included in the kit. Everyone can choose or make a case for the finished product based on the place where the amplifier is installed in the car and other factors.

Let’s take a look at the modules included in the kit.

1. The NM2012M single-channel low frequency amplifier is an evolution of Rod Elliot’s class AB amplifier circuit design. The amplifier is quite modern, especially when using a new element base. According to Elliot’s circuit design, a huge number of amplifiers were developed and assembled, both repeating the circuit and with some variations. The author claims that he did not receive any negative feedback on his project. The amplifier is reliable, stable and predictable, which is largely determined by the simplicity of the proposed circuit. According to user reviews, the sound is exceptionally good, and quite pulls on the Hi-Fi class with a low cost of electronic components and low labor costs for assembly and configuration.

The amplifier is extremely reliable and stable in operation. The circuit design uses auto-biasing of the quiescent current of the transistors, which allows the amplifier to be used in a wide temperature range, which is necessary for automotive applications.

four output transistors. They are located on the printed circuit board in such a way that a common radiator, or individual radiators for each transistor, can be easily installed. The author does not recommend using the amplifier without a heatsink, even at the lowest power for a short time. You can find suitable radiators on the Master Kit website.

2. To build any subwoofer channel, a low pass filter is required, which is included between the signal source and the amplifier. It can be either passive or active filter.

The NM0103 active low-pass filter offered in the described kit is based on a specialized PT2351 microcircuit, which is used in high-end industrial subwoofers.

Fig.3

The stereo signal through the input circuits enters the internal buffer stages of the microcircuit, where it is converted into a monophonic signal, and enters the third-order Sallen Key filter implemented in the microcircuit. There are two sets of capacitors in the kit to select the cutoff frequency: 60 or 80Hz, to choose from. After processing by the filter, through a decoupling capacitor, necessary for DC decoupling, the signal is fed to the subwoofer amplifier. This low-pass filter can be connected directly to the final amplifier of a subwoofer without using a preamplifier. The amplification factor of the microcircuit is about 10 times in voltage, so the maximum undistorted signal with an amplitude of about 2 volts can be obtained at the output. This is more than enough for most power amplifiers.

The filter is powered by its own regulator, so it can be connected to a 12-15 volt power source from a car battery or alternator.

3. Since the amplifier requires a bipolar power supply, this supply is included in the kit as an assembly kit NM0605.

Fig.4

The source is a pulse converter of unipolar voltage 12V to bipolar voltage ± 35V with a power of up to 200 W, which meets the requirements of the NM2012M amplifier in terms of supply voltage and power consumption.

The set of electronic components for assembling the power supply includes an already manufactured pulse transformer, which usually causes the greatest difficulty in the manufacture of this type of device on your own. But the three chokes included in the circuit are proposed to be wound by ourselves. Their manufacture is not too difficult, but quite useful for beginner electronics engineers.

The power supply must be connected to the car’s on-board network and to the amplifier with a wire with a cross section of at least 1.5 mm2. In no case do not plug the converter into the cigarette lighter socket, it is not designed for a current of 27 A, consumed by the converter at maximum power.

You can save a lot by purchasing Master Kit devices in sets. Such kits are formed from functionally complementary modules based on their technical characteristics.

Master Kit offers kits in different product categories:

– training kits;

– for home and garden;

– multimedia;

– for cars;

– 3D drawing;

– laboratory.

The list of kits is constantly updated, so we recommend that you subscribe to our news and be always aware of new products and special offers on the Master Kit website.

We also suggest that you familiarize yourself with other materials on the topic of sound amplification and building home and car sound amplification systems on our website, for example:0002 Overview of audio frequency amplifiers BM2043M and BM2043Pro

Over the years of working with car audio, we have selected and repeatedly tested sets of speakers, an amplifier and a subwoofer to basicly improve the sound of a standard audio system. The kits consist of a two-component and coaxial system, as well as a 5-channel amplifier and a subwoofer. And are designed to replace the regular car audio in most cars. In terms of price / quality ratio – this is an ideal option for an acceptable cost.

You can choose from three proposed replacement options to suit your taste. Below we have tried to describe each set separately.

The price is for a set of speakers, an amplifier and a subwoofer with the installation and manufacture of internal spacer rings for proper installation of acoustics. Work on the replacement of acoustics and amplifier takes us no more than one working day.
