1x60W Mono Amplifier Board TPA3118 - Compact 12V/24V Power Module

In this review we look at the 1x60W Mono Amplifier Board with the TPA3118 chip and explain who will get the most from it. The bottom line: this compact digital amp module is best for DIYers building a single high-power driver for a Bluetooth speaker, car audio upgrade, or custom home install because it delivers clean, efficient power from a low 8 to 24V supply. Our review found the board produces consistently good sound quality for the class while keeping power consumption modest and installation straightforward.

Key Features

• Mono 60W output: Delivers a single 60W channel that is suitable for driving a full-range or subwoofer speaker in a mono configuration.
• TPA3118 amplifier chip: Uses a modern Class D amplifier chip that keeps distortion low and efficiency high for longer battery or vehicle run time.
• Wide voltage range: Operates from 8 to 24V DC so it works with typical 12V car systems or larger 24V battery packs without extra conversion.
• Low power consumption: Designed as a digital module to minimize idle draw and heat compared with older analog amps, making it suitable for enclosed DIY builds.
• Simple integration: Small board format and straightforward power and input terminals make it easy to add to Bluetooth speaker projects or home audio modifications.
• Single-channel focus: Being a mono board simplifies wiring when a dedicated single driver or subwoofer is required.

Who It's For

This board is aimed at hobbyists and makers who need a compact, single-channel amplifier for a custom speaker or a car audio tweak. If you are assembling a Bluetooth speaker or converting a single driver into a powered unit, the 1x60W board offers a practical balance of power and efficiency.

It is less suitable for someone who needs stereo output without using two boards or an integrated stereo amplifier. Users expecting a plug-and-play consumer amplifier with a full enclosure and controls should look elsewhere; this module is intended for people comfortable with basic wiring and mounting in DIY projects.

Pros & Cons

Pros

• Compact mono 60W output provides strong drive for a single speaker or subwoofer.
• Efficient TPA3118 Class D design keeps heat and power draw low in most setups.
• Wide 8 to 24V supply range adds flexibility for car and battery-powered applications.
• Simple board layout makes it easy to integrate into custom speaker builds.

Cons

• Mono only, so stereo setups require two boards or a different product.
• Module is a bare board intended for DIY installation, not a finished consumer enclosure.
