The main difference between a Bluetooth amplifier and other car amplifiers is that you can stream music directly into it from all your Bluetooth-enabled devices.
A Bluetooth car amp simply rules out the need for buying a head unit saving you several bucks in the process. The following picks are the top in the market in terms of quality features and durability.

Kenwood KAC-M5024BT
Power: 50 watts RMS x 4 (@4Ω, 14.4V, 20Hz-20kHz, ≤ 1.0% THD+N);
@2Ω: 75 watts RMS x 4 (@2Ω, 14.4V, 20Hz-20kHz, ≤1.0% THD);
Bridged: 150W x 2 (@4Ω, 14.4V, 20Hz-20kHz, ≤1.0% THD)
Class: D
Channels: 4
Kenwood KAC-M5024BT 4-channel amp is our bang-for-the-buck option because of its advanced technology and its multi-application combined with a great price. Our previous pick, the Kenwood KAC-M1824BT, has been replaced by this one.
It’s not only suitable for your car but can also be installed on your motorcycle, ATV, and boat. This is possible because the amplifier is equipped with a conformal-coated main PCB which offers protection from outdoor moisture and salt from marine environments.
The Bluetooth connection allows you to operate your music wirelessly which is way more fun than using RAC input cables which can let you down at times.
Its compact size and water resistance properties make it really suitable for use in environments where amplifiers were not previously installed due to lack of space and the damage caused by exposure to environmental conditions.
It is waterproof and dustproof and comes with an IPX66/67 certification. The IPX66/67 certification enables it to perform even when exposed to water. This makes it suitable to operate on a boat, ATV, and motorcycle. It is tested for corrosion resistance against salt spray and salt fog under ASTM B117.
The SMART remote controls Bluetooth on and off functions, volume, skip tracks and EQ/Preout presets.
If an aftermarket unit without preamp output is used, the amplifier’s power wire is connected directly to the power line of the head unit. This is because this amplifier contains a signal-sensing turn-on feature that turns your amplifier on when a signal from the unit input is detected. This feature eliminates the need to install a turn-on lead to the amplifier’s power control wire.
