How to connect the buffer?

If you want to listen to morequality, clean and clear sound, you can connect a subwoofer to the radio. In order to understand how to connect the buffer, it is necessary to know that there are different kinds of sabas.

Kinds of submarines

So, subwoofers are of two types:

  1. Passive (needs an amplifier).
  2. Active (in the amplifier does not need).

Ways of connection will also be different.


List of tools that may be needed during the work:

  1. Amplifier (if a passive sub is connected).
  2. Acoustic cable.
  3. Adjustable wrench.
  4. Nippers.
  5. Set of wrenches.
  6. Knife for stripping wires.
  7. Pliers.

Scheme how to connect the buffer

Connecting an active subwoofer

To do this, you need to perform a few fairly simple steps (in which case the amplifier is integrated into the system, and it does not need to be connected separately):

  1. First you need to get the car radio from the connector where it is located. Also it is necessary to find two entrances.
  2. Using a line cord, you need to connect the sub to the main unit.
  3. In order not to have power problems, it is necessary to extend the wire to the buffer from the battery (its positive terminal).
  4. Next, do not forget to install the fuse. The ideal place for him is near the battery.
  5. It is also recommended to install separatelya capacitor for supplying the subwoofer (since low frequencies can create an additional load that the system can not handle). It connects to the power supply chain of the sub.
  6. Next, the speaker system itself is tuned.

Passive buffer connection

  1. The subwoofer is connected to the amplifier using acoustic cables.
  2. From the radio tape recorder to the amplifier, the signal will be transmitted using a double cable ("tulip" connectors must be installed at its ends).
  3. Wiring: "+" Pulls through the amplifier from the battery through the entire cabin; "-" must be connected to the mount. It can be any bolt on the body of the car (before connecting the bolt it is better to clean it).
  4. A thin post, which will include the amplifier during the radio switching on, is connected to the "+". Most often it is blue.

Precautionary measures

During all operations, the battery must bebe disconnected (you must first remove the terminal from the battery). It is best to start work with a power cable (most often it is closed with a rubber seal), which will have to be pulled into the cabin from under the hood space. And only after a thorough check of all connections can you connect the red wires of the battery.

It will also be useful to read articles about the features of the settings in our section Setup and Connection.
