The speaker system and subwoofer are designed to reproduce sounds of very low frequency, not exceeding 200Hz. Low-frequency sound is more difficult to determine the localization, that is, to isolate the place where it comes from. And in confined spaces, the subwoofer also creates low-frequency standing waves and vibration. All of these problems can be avoided by connecting the amplifier to a subwoofer that will remove the low frequency load.
Necessary
car radio, subwoofer, amplifier
Instructions
Step 1
Determine whether your subwoofer is active or passive. An active subwoofer has a built-in power amplifier; a passive subwoofer has no power amplifier at all.
Step 2
If the subwoofer is an active type, you need to find a parallel output labeled OUT or FULL RANGE OUT on it. Use this output to connect the subwoofer and the car radio with line wires.
Step 3
If the subwoofer is of the passive type, then connect the amplifier (using the same line wires) first to the car radio, and then connect the subwoofer to the amplifier.
