4 Contr ol Functions FRONT RCA Inputs RCA cables marked “FRONT” from head unit or fr om other line level device should be connected here. Use both inputs (L & R) for ster eo. FRONT Remote Input Use the supplied FEMALE quick connector to connect the REMOTE trigger lead from the head unit to the amplifier .
5 Contr ol Functions (cont.) “Q” Control “Q” Control is active when the highpass cr ossover is engaged and is centered on the selected crossover point. The range of operation is 0.7–1.2. REAR RCA Inputs RCA cables marked “REAR” from head unit or other line level device should be connected here.
6 Mechanical Functions Recessed RCA Inputs The input jacks are r ecessed into the body of the amplifier to provide clear- ance in tight mounting locations. Control Cover Removal and Reinstallation The cover panel is secured with two (2) captive coin-slotted scr ews.
7 Mechanical Functions (cont.) Amplifier Linking The design of the side panels enables multiple amplifiers to be used together without additional hardwar e. Wire Connection Amplifier accepts stripped wire dir ectly into the terminal blocks. Speaker outputs accept 8-gauge, and the DC power and ground accept 4-gauge.
8 Before Y ou Install Before you install the unit, disconnect the negative (–) battery cable in the engine compartment of the vehi- cle. Doing so will prevent damage to both the electrical system of the vehicle and the amplifier during installation.
9 13mm ( 1 / 2 ”) 548mm (21 5 / 8 ”) 225mm (8 7 / 8 ”) Choose the Mounting Location Plan your installation so that the amplifier is mounted where adequate ventilation is available.
10 Passenger and T runk Compartment Mounting If the amplifier is mounted under a seat, be sure that the vents do not become blocked. Do not allow seat padding or other obstructive material to press down on the amplifier . All Boston GT amplifiers have top panel controls.
Power/B+ and Power/GND Connection Strip approximately 5 / 8 " (16mm) of insulation. The positive (+) power wir e is installed into the amplifier terminal marked “B+.
12 Mono Subwoofer Operation If the amplifier is to be bridged and used with a subwoofer connected to the REAR channels, use the “SPEAKER OUTPUT” terminals marked for mono use. W ARNING! Subwoofer impedance must not fall below 2 ohms when in MONO mode.
13 Setup T uning—Full-Range Speakers (cont.) 4) Head Unit The head unit should have all controls such as bass, tr eble, balance, and fader set to the flat or centered position.
14 8) FRONT “Q” Control Once the FRONT highpass crossover point has been determined, use the FRONT “Q” control to incr ease the bass information centered ar ound the crossover point. Setting the front “Q” contr ol is done in conjunction with setting the levels on the input sensitivity and highpass crossover fr equency controls.
15 5) REAR Input Sensitivity Control Tu rn controls all the way counter clockwise (minimum position). In this position, the amplifier will be less sen- sitive to the input signal from the head unit. Slowly r otate this control clockwise until maximum undistorted playing level is heard fr om the subwoofers.
