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 amplifier if only the single amplifier is connected to this wire. If other devices are con- nected to this wire, the fuse value should be of sufficient capacity to handle the demand.

Wire Gauge

The amplifier accepts up to 4-gauge stripped wire at the DC power and ground input terminals, and 4-gauge is recommended. Wire runs should be kept to the minimum practical length.

Power 12v and Ground (GND) Connection

Strip approximately 5⁄8" (16mm) of insulation. The positive (+) power wire is installed into the amplifier terminal marked “12v”. The negative (–) wire is installed into the terminal marked “GND”. The ground wire should be as short as possible and connected directly to the chassis of the vehicle. Make sure that the chassis connection point is free of rust, grease, dirt, paint, and other materials that may insulate the ground wire from making proper connection. Tighten the 12v and GND terminals with the supplied 3mm hex wrench to secure the wire into the terminals. If the power wire must be routed through a drilled or existing hole, use a nylon panel grommet to prevent the insulation from fraying. 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

Use the supplied FEMALE quick-connect terminal to connect the REMOTE trigger lead from the head unit to the amplifier. Crimp connector to wire from head unit that controls remote turn-on (refer to head unit owner’s manual). Once the quick-connect terminal is crimped into place, carefully push connector onto recessed MALE REMOTE terminal adjacent to the RCA input pair (refer to the diagram on page 4).

Speaker Output Connection

Prepare each wire by stripping approximately 5⁄8" (16mm) of insulation. The positive (+) speaker wires are installed into the amplifier terminals marked “SPEAKER OUTPUT” / “+” (refer to the diagram on page 4). The negative (–) speaker wires are installed into the amplifier terminals marked “SPEAKER OUTPUT” / “-”. Tighten the “SPEAKER OUTPUT”, “+”, and “-” terminals with the supplied 2mm hex wrench to secure the wires into the terminals. If the speaker wires must be routed through a drilled or existing hole, use a nylon panel grommet to prevent fraying the wire insulation. Failure to do so could lead to an electrical short if the wire insulation is worn through and the speaker wires are shorted to ground.

Mono Subwoofer Operation

When the amplifier is configured for mono operation, use the speaker output terminals marked for mono use (refer to the diagram on page 4).

WARNING! Subwoofer impedance must not fall below 2 ohms when in MONO mode.

GT-2300, GT-275, GT-2125, GT-2200 specifications

Boston Acoustics is a renowned brand in the world of audio equipment, known for delivering high-quality sound across various platforms. Among their noteworthy offerings are the GT-2200, GT-2125, GT-275, and GT-2300 speakers, each designed with unique features and technologies that cater to audiophiles and casual listeners alike.

The GT-2200 is particularly celebrated for its robust construction and exceptional sound clarity. Featuring a 2-way design, it incorporates a 6.5-inch polypropylene woofer, which ensures deep bass response, complemented by a 1-inch silk dome tweeter for crisp high frequencies. This combination results in a well-balanced audio performance, making it suitable for various types of music. The speaker also boasts a frequency response range from 40Hz to 25kHz, allowing listeners to experience a rich soundstage.

Next, the GT-2125 takes a similar approach with its 2-way design but enhances the audio experience with a larger 8-inch woofer. This added driver size provides even more depth to the bass while maintaining clarity in vocals and instruments. The GT-2125 also features a sleek cabinet design that minimizes resonance and distortion, ensuring that the sound remains clean and true to the original recording. Additionally, its high-quality crossover network seamlessly blends the sound from the woofer and tweeter for a cohesive listening experience.

The GT-275 stands out with its powerful 3-way configuration, incorporating a 10-inch woofer, a mid-range driver, and a tweeter. This triad of drivers allows for a more dynamic sound reproduction, making it well-suited for home theater setups. The GT-275 is engineered with advanced technologies, including Boston Acoustics’ patented power handling capabilities, which help ensure that the speakers can withstand high volumes without compromising sound quality.

Finally, the GT-2300 offers a versatile experience with its bi-amping capability. Users can connect separate amplifiers to the woofer and tweeter, allowing for tailored sound adjustment based on personal preferences and room acoustics. This model features a durable cabinet design that offers both aesthetic appeal and acoustic performance.

In summary, Boston Acoustics' GT series, with models like the GT-2200, GT-2125, GT-275, and GT-2300, reflects a commitment to quality audio engineering. Each model showcases unique features and technologies, making them viable options for anyone looking to enhance their listening experience, whether for music or home theater systems. With their robust construction and superior sound quality, these speakers are sure to impress even the most discerning audiophile.
