BOSTON GTA
HIGH PERFORMANCE MOBILE AMPLIFIERS
Setting a new standard in value for high performance amplification, Boston’s new GTA amplifiers capture the best design, performance
and features from our acclaimed line of GT Reference amplifiers. GTA amplifiers feature front-mounted controls and connections,
Q-Tune™ for optimum system tuning, dedicated speaker level inputs for simple integration, as well as our new IMS™ (Integral Mounting
System) which reduces the overall amplifier footprint. With six models ranging from 50-Watts x 2 all the way up to a mono 800-Watt
amplifier, GTA can drive any speaker, any system and any configuration. So, whether you are building a system for stealth or show,
with stunning looks, an aggressive feature set, and crisp clean power—GTA Amplifiers are the right choice.
