We offer connections to the subwoofer either via spring loaded terminals or direct connect wiring.

Push Terminals are chrome plated, and are marked with a red and black colors to designate the positive and negative terminals. They offer the simplest installation and provide a nice secure connection.

Standard Push Terminals are made to accept a single 8ga wire and use a tab soldered directly to the push pin, to which the leadwires from the voice coil are soldered.

LARGE Push Terminals are made to accept a single 4ga or dual 8ga wires and use a heavy duty, extra-thick tab bolted to the push pin, to which the leadwires from the voice coil are soldered.

Direct Connect wiring offers the very best connection directly from your amplifiers output wiring to the voice coil of your subwoofer. Our direct connect wiring is securely attached to our interwoven braided lead wire via high temperature solder, then covered with heavy duty heat shrink. You can make your connection to the wiring via the twist and tape method, large wire nuts, crimp connectors, or solder.
