Connecting the Speaker Wires Using Spade Connectors

If you are not using the molded connector and wiring harness, you can use the integrated spade connectors to connect your speakers to your stereo or amplifier. The polarity indicators for the spade connectors are molded into the speaker housing next to the connectors.

You can use this table to identify the polarity and spade-connector sizes on the speaker.

Connector polarity

Spade connector size

Positive (+)

6.3 mm

Negative (-)

4.8 mm

NOTE: Connect speaker wires to the speaker using either the wiring harness or the spade connectors. It is not necessary to connect speaker wires to both at the same time.
  1. Connect marine-grade spade connectors to the speaker cables.
  2. Connect the spade connectors to the spades integrated into the speaker housing.
