You’re now equipped for the open road. Your high performance GTA amplifiers are engineered to perform and built to last. These products represent the pinnacle of performance and innovation that Boston Acoustics is famous for. We hope you enjoy your amplifier and the road ahead. Technical Specifications: Rated Power (CEA-2006-A): @ 4-Ohm (Stereo): @ 2-Ohm (Stereo) @ 4-Ohm (Mono) Impedance Stability: Stereo: Mono: Frequency Response (-3dB): Signal-to-Noise Ratio: (A Weighted) THD+N: Highpass Cross

To engage Q-Tune move the selector switch to the “ON” position (refer to the diagram on page 3). 6) GTA-RSL Control The remote level control (GTA-RSL) gives you independent level adjustment of the subwoofer’s output level beyond the standard system volume control. Please refer to the RSL’s manual for installation instruction. The GTA-RSL is available separately, please consult your authorized Boston Acoustics dealer. fuseConnection Diagram: ring a Subwoofer (80Hz Lowpass) Tuning The Amplifier -

Failure to do so could lead to an electrical short if the wire insulation is worn through and the power wire is shorted to ground. Remote Input Connection Connect the REMOTE trigger lead from the head unit to the amplifier using the 3mm hex wrench to tighten the connector on the power block of the amplifier. (refer to the diagram on page 3). Speaker Output Connection Prepare each wire by stripping approximately 5.8” (16mm) of insulation. The positive (+) speaker wires are installed into the ampl

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

(refer to the diagram on page 5). 2) Input Sensitivity Control Turn both front and rear controls all the way counterclockwise (minimum position). In this position, the amplifier will be less sensitive to the input signal from the head unit (refer to the diagram on page 5). 3) Highpass & Lowpass Crossover Controls Crossovers should be turned “OFF” during this phase of setup . Move the HIGHPASS and X-OVER switches to the “OFF” position (refer to the diagram on page 5), with these settings, full-ra

If the vents are obstructed, this could lead to premature thermal shutdown or amplifier failure. 6 Installation - Wiring Amplifier Fuses Although the amplifier has an internal fuse, additional fuse protection should be installed as close as possible to the battery on the positive (+) power wire going to the amplifier. An inline fuse should be installed at no more than 18" (46cm) on the positive (+) power wire. The rating of the inline fuse should equal the value of the internal fuse of the ampli
