Fuses protect both the amplifier and the electrical system of your vehicle from faulty conditions.
If you must replace a fuse on the amplifier, always use a fuse of exactly the same type and rating of the one you are replacing. A different type of fuse or rating may result in damage or cause a fire. Please refer to your owner’s manual for reference on fuse size and type.
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.
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.
Please be advised that 'Professional' installation of all of our products is recommended and encouraged. Installation by a professional installer increases the length of any applicable warranty on most Boss Audio Systems products. The warranty is void, however, on product that is damaged during installation by a non-professional installer. Professional installation should also ensure trouble-free usage for years to come.
High and Low Level Inputs
The R1002 has two different ways that you can get a signal into it. A Low level input and a High level input. A low level input is measured in voltages. It comes in the form of RCA outputs from the back of your receiver and goes to the RCA inputs on your amplifier. A high level input is measured in watts. It comes in the form one positive and one negative wire from the back of your receiver to and goes to the input terminal of your amplifier in the same wire form. Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for best audio performance. Note: Do not connect both the high level and low level inputs from your receiver to your amplifier at the same time!
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.
