Best Bluetooth Car Amplifiers [UPDATED]

Home » Car Amplifiers » Best Bluetooth Car Amplifiers [UPDATED]

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.

Bluetooth amplifiers are new in the market and have helped a lot of car owners who didn’t have a Bluetooth-enabled stereo. Before these amps hit the market, the original stereo had to be removed from the dashboard and get swiped with an aftermarket Bluetooth-enabled stereo.

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.

RMS: 45 Watts x 4 at 4 Ohms;
45 Watts x 4 at 2 Ohms;
Bridged: 90W x 2
Max: 400 watts
Class: D
Channels: 4

Kenwood KAC-M1824BT 4-channel amp is our bang for the buck option because of its advanced technology and its multi-application combined with a great price – as explained in Kenwood KAC-M1824BT full review.

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 that amplifiers were not previously installed due to lack of space and the damage caused by exposure to environmental conditions.

It comes with an IPX-5 certified remote. IPX-5 certification enables the remote to perform even when exposed to water. This makes it suitable to operate on a boat, ATV, and motorcycles. The IPX remote controls Bluetooth on and off functions and allows you to switch between Bluetooth and the RCA input as your music source.

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.
