Product Information

Power Meets Beauty

JBL’s GTR-104 4-channel amplifier has it all: it’s good-looking, powerful, and boasts features that other amplifier manufacturers just don’t implement into their own designs. Shame on those other manufacturers. This car amplifier has enough horsepower under the hood to run your vehicle’s speaker system. Oh, and what’s so unique about this amplifier? How about the fact that it has Bluetooth for hands-free calling as well as audio streaming built into it? Cool enough yet? You don’t have to worry about your car’s lack of Bluetooth connectivity with this bad boy in the fray.

Revitalize Your Compressed Music

We all love the conveniences that compressed music offer us: more music thrown onto your iPhone, Android smartphone, or other digital music player than an old-school CD wallet could ever hold. However, we compromise on sound quality to jam all of this music onto these small devices. JBL addresses this concern with their Clari-Fi™ technology. This software analyzes the music and helps improve the sound quality of highly-compressed music files. You’ll be able to hear more detail and a broader dynamic range in your favorite tunes with this JBL car amplifier in the mix.

Built-in Bluetooth

The GTR-104 car amplifier has built-in Bluetooth so you can connect your Bluetooth-enabled device to it to stream audio or to handle hands-free calling. If you don’t have Bluetooth in your car already, this amplifier can handle that as well as give your speakers a healthy dose of power for louder output as well as better sound. Best of all, the Bluetooth car amplifier includes a control unit that can be mounted near your driver’s seat/radio area to answer those incoming phone calls – no more scrambling for your phone when a call comes through!

One Versatile Amplifier

This JBL car amplifier allows you to do something special. You can opt to use it in either 4-channel, 3-channel, or 2-channel mode. So now maybe you’re wondering why you have so many choices. For one major reason: it allows you to adapt as you change your speaker configuration or perhaps add a small subwoofer. You may not have to worry about buying another amplifier in the future. See the power output differences under the “Specifications” tab.
