3. Check for any hazards or obstructions such as gas tanks, fuel or brake lines, and wiring harnesses before mounting the amplifier. They may also impair a driver’s ability to hear traffic sounds or emergency vehicles. Use common sense and practice safe listening habits when listening to or adjusting your audio system. 4. Pick a mounting location that will provide adequate access and ventilation and protect the amplifier from heat, moisture, and dirt. 5. Avoid sharp metal areas when routing cabl

10. Due to the high-frequency MOSFET switching power supply, filtering the power cable is not generally required (remember that the amp can’t deliver full output if the power supply is restricted). Proper grounding of the signal source is mandatory for the amplifier to reach its performance peak. If the RCA inputs are not grounded adequately via the signal source, electrical noise from the vehicle may be picked up in the system. © 2003 Directed Electronics, Inc FRONT PANEL CONNECTIONS/CONTROLS N

Installed correctly, your ProSeries system will offer unprecedented performance for many years to come. Warning This manual explains only the assembly and placement of the various components, not the techniques required to perform the installation. If you do not have the experience these procedures require, we strongly recommend you consult your Boston Acoustics dealer about professional installation. 2 System Contents Here's what comes with this system (two each): 6.53 System 6.5 System

For mid-bass/midrange settings, try to keep the setting low enough to keep your sound stage in front of you, without overdriving the speaker. It will be to your advantage to spend some extra time with this adjustment, listening to familiar music or system set-up discs to achieve the kind of musical reproduction that you prefer. • The gain adjustment allows you to set proper signal match for clean, quiet amplifier operation. For full-range and simultaneous stereo/mono bass applications, start by

The FLAT setting is used for full-range or mixed stereo/mono applications. FIGURE 2—AMPLIFIER CONTROLS 4. BASS EQ -(model 500 only) these switches activate an 8 dB bass boost circuit. Use as necessary for low frequency enhancement. 5. CROSSOVER FREQUENCY - controls the frequency range of the amplifier. Each half of the amplifier can be set independently for optimum performance. 6.

For summed subwoofer applications, connect RCA cables per the input jack marking. Simultaneous stereo/mono operation (two channel shown) © 19

Just pick a reasonably flat panel, drill a few holes, fasten a few screws, and you’re listening to stereo. INSTALLING OVAL SPEAKERS IN REAR DECKS OR FLAT SURFACES Most cars are factory-equipped with speaker openings in the rear deck (package shelf). By examining the underside of this panel, using trunk access, you will probably find at least one (usually two) oval-shaped holes in the steel underliner of the rear deck. The size of these holes vary with the make of car, but the most common opening
