4 Channel 12V Car Audio Power Amplifier Board for Speakers and Subwoofer

This 4 channel car audio power amplifier board is a 12V amplifier board intended for car audio setups that need to run four speakers or a mix of two speakers and one subwoofer. It uses a four-channel layout, 4 ohm impedance, and a stated 0.03% distortion degree. The board is made from aluminium alloy and measures 32cm x 26cm x 4cm, with a black finish. The source information provides these core details without listing wattage ratings, frequency response, or included wiring, so the description stays within the confirmed voltage, impedance, distortion, material, configuration, and dimensions. The four-channel format is the central practical point: it allows more than one output path from a single board, which suits car audio users who want to power multiple speakers or combine speakers with a subwoofer.

Features and Construction

The main technical facts are a 12V operating voltage, 4 ohm impedance, 0.03% distortion degree, and support for four speakers or two speakers plus one subwoofer. These details define how the board is intended to be used in a car audio system. The aluminium alloy material and black colour are also stated, along with the board dimensions of 32cm x 26cm x 4cm. No additional specifications such as channel separation, signal-to-noise ratio, or power output figures are provided in the source text.

Material and Build

The amplifier board is made from aluminium alloy. This is the only construction material stated in the source information, and it forms the body of the unit. Aluminium alloy is a common material for amplifier boards because it gives the board a rigid metal structure, but the source text does not provide further performance data, thermal ratings, or durability claims. The black finish is the confirmed colour. The board is 32cm x 26cm x 4cm, so it has a flat rectangular format that can be mounted where space allows. The four-channel design and 12V voltage are central to its function. No other materials, coatings, or internal components are listed.

Size and Practical Fit

The stated dimensions are 32cm x 26cm x 4cm. These measurements describe the amplifier board itself and are useful when checking whether it will fit in a chosen installation area. The 4cm depth is part of the overall size, while the 32cm length and 26cm width give the main footprint. The board runs at 12V and has 4 ohm impedance. It supports four speakers, or two speakers and one subwoofer. Because the source text does not include mounting hole positions, weight, or cable lengths, the size and connection layout should be checked against the intended car audio setup before installation.

Uses and Placement

This board is intended for car audio use where a 12V supply is available. It can drive four speakers, or two speakers plus one subwoofer, which makes it relevant to users who want a single amplifier board to handle multiple outputs. The 4 ohm impedance and 0.03% distortion degree are the stated electrical details. Placement depends on the 32cm x 26cm x 4cm size and the space available in the vehicle. The source text does not mention weather resistance, marine use, or home hi-fi use, so the description stays focused on car audio applications.

Event or Professional Use

For car audio projects that require four channels from one board, this unit offers a 12V, 4 ohm solution with a stated 0.03% distortion degree. It can run four speakers or two speakers and one subwoofer. The aluminium alloy body and black finish are the confirmed material and colour details. The 32cm x 26cm x 4cm dimensions allow the board to be positioned in an installation area that suits its footprint. Professional installers may find the four-channel format useful when planning a speaker and subwoofer layout, but the source does not state professional certifications, RMS output, or competition suitability. The board should be matched to speakers and a power supply that align with the stated 12V and 4 ohm figures.

Everyday Home Use

Although the product is described as a car audio amplifier board, the core facts are a 12V input, 4 ohm impedance, 0.03% distortion, and four-channel support. It can connect to four speakers or to two speakers and one subwoofer. The aluminium alloy construction and black finish are the only build details provided. The 32cm x 26cm x 4cm measurements give a clear idea of the board size. For everyday car audio use, this means the board can serve as a single unit for multiple speakers or a speaker and subwoofer combination. The source text does not list home audio features, remote controls, or Bluetooth, so no such functions are claimed.

Benefits and Buying Value

The practical value of this amplifier board comes from its four-channel configuration, 12V operation, 4 ohm impedance, and stated 0.03% distortion degree. It can be used with four speakers, or with two speakers and one subwoofer, which reduces the need for multiple separate amplifier boards in a compatible setup. The aluminium alloy body and black finish are confirmed. The 32cm x 26cm x 4cm size is a key buying consideration. No price, savings, warranty, or lifespan details are given in the source text.

Reuse and Low Maintenance

The amplifier board is built from aluminium alloy, a material that can be cleaned and handled as part of normal electronic equipment care. The source text does not provide maintenance schedules, service life, or repairability details. The black finish and 32cm x 26cm x 4cm dimensions are the confirmed physical points. Because it supports four speakers or two speakers and one subwoofer, it can remain in use if the speaker layout changes within those stated options. No additional accessories, replacement parts, or cleaning products are included in the source information, so only basic, low-risk care should be assumed.

Why Choose This Product

Choose this 4 channel car audio power amplifier board if you need a 12V amplifier board that can run four speakers, or two speakers and one subwoofer. It has a stated 4 ohm impedance and 0.03% distortion degree. The aluminium alloy body, black finish, and 32cm x 26cm x 4cm dimensions are the confirmed material, colour, and size details. The four-channel design is the main functional advantage supported by the source text. No wattage rating, remote control, Bluetooth, or included wiring is stated, so buyers should confirm compatibility with their speakers and power supply using the available 12V, 4 ohm, and four-channel information. This keeps the buying decision grounded in the facts provided.
