About the EFX GM Post Standard Battery Terminal

New battery terminal accommodates more connections

You want to add an amplifier to your GM vehicle's audio system, but there's no room at the battery terminal for any more connectors. Replace your GM's side-mount battery post with this terminal from EFX, which will accept all of your vehicle's factory wiring plus the ring terminal for an amp. This 1-3/8" heavy-duty chrome-plated brass post can be used on either positive or negative battery terminals. Warranty: 1 year.
