Failure to comply with this warning could result in injury or death. Insignia NS-A1000 Car Stereo Amplifier Caution Protect connecting wires and parts to avoid damage or short circuits. To protect the amplifier unit, make sure the power connection from the positive (+) battery terminal to the amplifier is correctly fused. The sound system must be turned off before checking the amplifier. When you replace an amplifier fuse, make sure you use the same fuse type and capacity (25AX2). High powered audio systems in a vehicle are capable of generating Live Concert high levels of sound pressure, Continual exposure to excessively high volume sound levels may cause hearing loss or damage.Also,operation of a motor vehicle while listening to audio equipment at high volume levels may impair your ability to hear external sounds such as; horns, warning signals, or emergency vehicles, thus constituting to a potential traffic hazard. In the interest of safety, Consumer Electronics recommends listening at lower volume levels While driving. Features • 3-way protection: thermal, short-circuit, and over voltage • 2-ohm stable stereo • P.W.M mosfet power supply • Power and protection indicators • Selectable crossover-hi/low and bypass • 18 dB bass boost with selector switch sub (50 Hz) • Variable high pass and low pass crossover points (40 Hz-250 Hz) • Platinum plated terminals and RCA jacks • Variable input sensitivity • Soft delayed remote turn-on • Low level and high level inputs • Tri-mode capable for powering sub (observe impedance) • Chrome end caps conceal electrical connections • Remote dash-mount bass control Planning the installation Before beginning the installation, consider the following: • If you plan to expand your system by adding other components sometime in the future, make sure that you provide adequate space for the additional components, and that cooling requirements are taken into consideration. Insignia NS-A1000 Car Stereo Amplifier • If your source unit is equipped with both low-level (pre-amp level with RCA connectors) and high-level (speaker level) types of outputs, use the low-level outputs (RCA connectors) for the amplifier inputs. This type of connection provides for increased bandwidth and you can still utilize the speaker outputs to drive the (smaller) front speakers directly. Note The distortion level is considerably lower from pre-amp (low level) outputs, than from speaker (high level) outputs. • Are your components matched? The peak power rating of your speakers must be equal to, or greater than, the amplifier output rating. They also must be 2-8 ohms impedance (normally printed on the speaker magnet). • Consider both the length of your leads and the routing when determining the mounting location. Pre-amp input jacks require a length of high-quality shielded male-to-male RCA patch cord. Setting up your amplifier Mounting the amplifier Warning Check the layout of your automobile thoroughly before drilling or cutting any holes. Take extreme care when you work near the fuel tank lines, hydraulic lines, or electrical wiring. Do not mount this system so that the wire connections are unprotected and subject to pinching or damage from nearby objects. The +12V DC power wire must be fused at the battery's positive terminal connection. Before making or breaking power connections at the system's power terminals, disconnect the +12 V wire at the battery's end. Confirm that your source unit and other equipment are all turned off while connecting the input jacks and speaker terminals. If you need to replace the power fuse, replace it only with a fuse identical to that which is supplied with the system. Using a fuse of different type or rating may result in ...
