The presence of a subwoofer can significantly improve the performance of the car's speaker system, but this will be possible only if properly connected to the amplifier. Unfortunately, this operation is not as simple as it seems to many. In order for everything to work properly, it is necessary to take into account a number of quite important parameters. In this article we will try to figure out how to properly connect the subwoofer to the amplifier.

Before you start connecting the active and passive subwoofer to the amp, it makes sense to compare the RMS values ​​(the power at which the equipment can work with a real sound signal for an hour without damage) of the subwoofer and amplifier. The equipment should be selected in such a way that this amplifier parameter is higher than that of the subwoofer. Otherwise, the permissible power level (clip) may be exceeded, which is one of the most common types of speaker breakage.

For optimum performance, the power of the amplifier and subwoofer should be approximately equal.

What you need to connect?

To connect the subwoofer to the amplifier, you first need to make sure that you have everything you need. To install the subwoofer and amplifier in the car will need:

It is also important to remember that in order for the subwoofer to work correctly, it is necessary to turn on the LPF filter that cuts off frequencies above 50-100 Hz.

How to connect a subwoofer to a four-channel amplifier

A classic of connecting car speakers to a four-channel amplifier is a circuit with two speakers and one subwoofer.

So how do you connect a subwoofer and speakers to an amplifier?

The standard option is to connect two speakers and one subwoofer. Each speaker connects to a separate channel, while a subwoofer is installed by a bridge. The important point is that the speakers should be connected to the front channels, and the subwoofer to the rear.

It is also possible to breed two subwoofers in separate rear channels.
