Boston Acoustics, a longtime leader in premium sound components for aftermarket mobile audio systems, announces six new models for its GTA Series of amplifiers. The high-performance mobile audio amplifiers now offer up to a 25% increase in power over their predecessors, while maintaining the same price points offering unprecedented performance to value ratio.  “The original GTA amplifiers were the perfect gateway to a new market segment for Boston,” said Dave Jaques, Aftermarket Mobile Audio Product and Marketing Manager for Boston Acoustics. “Building on a great foundation, we challenged our engineering team to increase power without sacrificing feature set, footprint or Sanjay Sharma, National Sales Manager adds, “Ultimately, we’ve made a solid top performer even better—offering feature-rich models to suit the sub $500 amplifier category. Providing our dealers with highly competitive product in this price range, allows us to reach new generation of Boston customers.”

Performance Features

Boston GTA amplifiers employ a host of performance-enhancing features not

commonly found in amplifiers at their price points. GTA amplifiers are available in

both Class AB and Class D designs, as well as a hybrid model. The high-efficiency

Class AB models are specifically designed for better sound quality in full-range

applications. The Class D models provide optimum power delivery for subwoofer

applications, while the hybrid 5-channel amplifier offers the best of both worlds.

All models feature adjustable 12dB/octave highpass and 12dB/octave lowpass

crossovers. These can be combined in the Class D models for bandpass operation,

using the highpass crossover as a subsonic filer. To offer further system “tweaking”

power, Boston has incorporated Q-Tune™ bass enhancement in all models, and,

in the Class D models, user-adjustable “Q” for each amplifier’s highpass crossover

filter to allow the user to optimize the bass from the subwoofer system without

overloading.

Because today’s vehicles are full of noisy electronic components that sometimes

cause noise interference, Boston’s SST™ (Symmetrical Signal Topology) system

uses balanced asymmetrical inputs for noise cancellation to ensure that any noise

introduced will be removed from the audio path, not amplified by it.

Installation Features

Boston engineers developed the GTA amplifiers with very specific design goals

to ensure that they would fit into as many spaces as possible. Using an extruded

aluminum chassis, GTA amps pack a ton of features and power into a compact

footprint. Further reducing the overall footprint, Boston’s IMS™ (Integral Mounting

System) allows for direct mounting through the amplifier without the need for

extended mounting feet or tabs, saving more precious space.

Dedicated High- (speaker level) and Low- (RCA) level inputs with wide-ranging

input sensitivity (200mV to 5V for Low, and 400mV to 10V for High) mean that

compatibility is extended to the widest possible range of head units, factory

adapters, and system preamps. All input/output connections are located on one

side of the amplifier, with optimal angled speaker and power blocks for easy wire

connections. The recessed control panel permits clean installation with wires

concealed.

Careful consideration was paid to maintain cosmetics of the new GTA amps,

ensuring cohesive blend with legacy models—a key benefit for both dealers and

customers alike. All GTA amps are designed to increase flexibility and installation

ease while retaining full use of interior space, which is so critical in today’s smaller

Lastly, the GTA-RSL is an optional remote level control that gives the user

independent level adjustment, from the comfort of the driver’s seat, of the

subwoofer’s output level, beyond the standard system volume control.
