High Performing GTA Amplifiers
The GTA-400M is a Class D monoblock amplifier rated at 250W x 1 channel @ 4 ohms, and 400W x 1 channel @ 2ohms, making it perfect when amplifying a single subwoofer or even a pair of entry-level subwoofers within the allotted power ratings. Its Class D rating will allow for the highest efficiency possible while still maintaining a good value.
GTA series amplifiers have been manufactured by Boston Acoustics to provide the perfect amount of power to any speaker, subwoofer, and car audio system at any configuration. GTA amplifiers feature a Symmetrical Signal Topology (SST™) that creates noise cancellation by using asymmetrical balanced inputs. This makes them more efficient with less distortion. The option of low-level, or high-level inputs will allow the installation of these amplifiers into any system with ease. The Q-Tune™ technology will combine your main speakers with the subwoofers, giving you bass up front and a whole new way of enjoying your music. The fully adjustable low-pass/high-pass crossovers will allow for complete control of all frequencies allowing for personalized tuning of your audio system to better meet your musical needs and preferences. GTA amplifiers offer high performance with advanced features and technologies. So when looking for reliability, quality, and crisp clean power Boston Acoustics' GT series amplifiers are your only stop.
