procedure at the end of this manual to confirm that your inputs are in correct electrical phase and the proper bass response is being produced.
Low-Level Inputs:
If your source unit only has
POWER WIRE (All Models)
The power wire must be fused and connected directly to the positive terminal of the battery to provide a power source with a low voltage drop and low noise. Do not make the power connection at the fuse block or any point other than the battery. Improper power sources can reduce output and cause distortion.
The fuse holder should be connected to the battery'spositive terminal. The fuse is designed to prevent fire or damage to your car, should the battery wire short to ground. Wait to insert the fuse into its holder until all wire connections have been made.
If it is necessary to lengthen the battery wire, add the required length between the amplifier and the fuse holder, not the fuse holder and the battery. If you need to extend t he battery wire, use 12 gauge
or larger for. It is best to use as short a wire as possible.
Be sure you DO NOT run the power wire next to the input cables of the amplifier this will induce noise. Avoid running the power wire near the radio'santenna or power leads, or near sensitive equipment or harnesses. The power wire carries substantial currents and could induce noise.
GROUND WIRE (All Models)
The ground wire must be connected directly to the vehicle chassis near the amplifier. We do not recommend extending the ground wire in any installation, as this can cause unwanted ground loops.
The ground point in the car should be a piece of chassis metal that is part of or welded to the main body of the vehicle. Painted surfaces should be scraped or sanded clean to expose the bare metal before the ground lug is bolted down. (Cover the bare metal area with paint
