This amplifier is bridgeable and stable at 2-4 Ohms, making it a versatile choice for any audio setup. ## Description Product Description Put your music into high gear and take off with the BOSS Audio PF1800 Class A/B 4 Channel Full Range Amplifier. With 1800 Watts Max Power and MOSFET power supply, this Amplifier is ideal for your entire audio system. It can power up your speakers, subwoofers or a combination of both. Customize the sound with Variable Low Pass Crossover, Variable High Pass Crossover and Variable Bass Boost. Bridge the channels for more power and flexibility. Both low and high level inputs are available so that if your receiver does not have one, it will have the other. Short Protection Automatic shut-off protects the amplifier if it gets too hot or if speakers fail causing a short. Switchable Input Sensitivity Switchable input sensitivity provides adjustable control over the input signal from the head unit to achieve customized balance between power and sound quality. Class A/B, Full Range, MOSFET Power Supply 1800 Watts Max Power, 450 Watts @2-Ohms x 4 Max 225 Watts @4-Ohms x 4 Max, 900 Watts @4-Ohms x 2 Max Bridged Thermal Overload Speaker and Short Protection, Power and Protection LEDs Variable Low Pass Crossover, High Pass Crossover High and Low Level Inputs, Bass Boost and Gain Control Specifications: Dimensions - L 13.5 x W 10.31 x H 2.5, Weight - 5 Lbs. MOSFET Power Supply Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output. Class A/B Our Class-A/B amplifiers feature specific linear circuitry that increases sound quality and power output while reducing distortion and improving efficiency. Bridgeable Combine the channels of a 2 or 4 channel amplifier to provide a dramatic increase in power output. 2 Ohm Stable 2-Ohm stable comfortably powers speakers or subwoofers when in use at 2-Ohms, resulting in more power and volume. Variable Low Pass Filter Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer. Variable High Pass Filter Variable high-pass filter gives you the ability to filter the frequencies that pass through to the full range speakers. Variable Bass Boost Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it. High and Low Level Inputs High-level inputs accept speaker output signals and low-level inputs accept pre-amp output signals to allow for the addition of amps and processors to standard factory or aftermarket source units. Power Input Terminals When installing all Boss Audio Systems amplifiers, it is important to use the maximum gauge of wire that the power terminals will accommodate. For instance, if an amplifier has 4 gauge power and ground terminals, use high quality 4 gauge multi-strand copper wire to make your power connections. This maximizes the amplifier’s ability to draw the required power upon demand. This also helps prevent overheating that could cause failure. Always make sure your vehicle’s electrical system is capable of handling the current demands from any after-market accessory. Please refer to the amplifier’s owner’s manual for correct wire gauge sizes. Proper Grounding Proper grounding is essential for any electric accessory in a vehicle. Some key points to remember: Keep the ground as short as possible. Connect the amplifier’s power ground terminal to the closest point on the chassis of the car. Keep this ground wire to less than 39-inch (100 cm) in length. Use 4 gauge (or heavier) wire. Scrape any paint away, use a star washer to “bite” into the metal and secure it tightly using a grounding lug. Any steps that aren’t followed properly will result in a higher resistance at the ground point, causing unnecessary heat, high current draw, and potentially damaging the electrical accessories in the vehicle. Fuses Fuses protect both the amplifier and the electrical system of your vehicle from faulty conditions. If you plan on using multiple amplifiers in your system, be certain that you have the appropriate sized gauge wire to accommodate the current demands for all amplifiers and that the wire is fused correctly at the battery. Connect an empty fuse holder within 18-inch (45 cm) of the car battery and run a 4 gauge (or heavier) cable from this fuse to the amplifier location. A fused distribution block is recommended when using several amplifiers or accessories. Gain / Input Sensitivity The “Gain” or “Input Sensitivity” selectors on an amplifier are not to be mistaken for a volume setting. This setting allows users to match the gain from the source unit. To set these selectors properly, you must “defeat” any processing on your source unit. In other words, make sure Bass, Treble, and Subwoofer levels are set to “0” on your source unit before adjusting the gain or input sensitivity selector on your amplifier.
