They're generally design to go between speakers and an existing stereo head unit, but if you're alright with having limited inputs they'll also work by themselves.

They are all on the more expensive side, but they also generally offer a significantly larger amount of RMS watts per a speaker, which is absolutely essential for those trying to drive multichannel systems or large subwoofers at loud volumes while maintaining quality. If you're trying to add Bluetooth to a high-fidelity, high-volume speaker system you're going to want to look at the higher-end models on our list, such as the Kenwood Compact Automotive Amplifier, Infinity K5, and Rockville RXM. The situations in which someone will desire an amplifier that features Bluetooth capability are quite varied, so we've included a wide range of models on our list best suited to several common predicaments. As a general rule, the more channels you have, the more expensive the unit, and the larger it is, so these are also important considerations when buying the ideal Bluetooth amplifier to suit your requirements.

If you wish to power two drivers and a subwoofer, then a minimum 3 channel amplifier is required.

smaller units, such as the Dutison Mini Audio Amplifier, have just two channels, meaning they are only able to power two speakers or one subwoofer. When sizing up your amp, prioritize the RMS (root mean square) rating over peak power output, as this is a better indicator of true power at safe operating levels, and is the rating usually considered by industry professionals.Īnother thing to take into account is the number of channels you need, and this is determined by the number of speakers you have, and how you have them configured. It is also useful to check that it is CEA 2006 compliant, to ensure that the manufacturer isn't making bold and unsubstantiated claims with regard to their power output. When choosing a suitable amplifier, you should be sure that it matches the capabilities of your speakers, and that they are not underpowered enough that your amp is overdriven to the point of clipping.

This feature also makes these amps a popular addition to golf carts, especially given their small size. Many of those ranked here, including the Kenwood Compact Automotive Amplifier, Velex Water Resistant Amplifier, and the Massive Audio TX48 Trident, have the extra benefit of being waterproof, making them extra-resilient when used in exposed environments, such as marine applications and outdoor sports. This is particularly useful onboard boats, in trailers, ATVs, and other vehicles that may not have a dedicated stereo built-in. One of the primary benefits of owning a Bluetooth-enabled amplifier is the fact that you don't need a compatible head unit in order to stream music from a Bluetooth-enabled device, bypassing all the unnecessary functionality along the way.
