Car Wiring & Accessories

Car wiring accessories help you make connections that fit your wire and mounting hardware. We carry Install Bay terminals and connectors in a range of wire gauges and styles, so you can compare the details before choosing parts for your car audio installation.

How to choose ring terminals by wire gauge and stud size

For a ring terminal, match both the wire gauge and the stud opening to your connection point. The Install Bay YNRT38 fits 12–10 AWG wire and 3/8-inch studs, while the Install Bay BNRT14 fits 16–14 AWG wire and 1/4-inch studs. Both come in 100-packs. Check the stud size at the mounting point and choose a terminal made for your wire gauge.

Quick disconnects for matching terminals

When you need a detachable connection, match the male or female connector style and the mating-terminal size. The Install Bay YVMD250 is a yellow vinyl male quick disconnect for 12–10 AWG wire and .250-inch mating terminals. For smaller mating terminals, the blue Install Bay BVFD205 is a female quick disconnect for 16–14 AWG wire and .205-inch terminals. Each product comes in a 100-pack.

Crimp caps and other wire connections

For a closed-end wire joint, choose a crimp cap sized for the conductors. Install Bay offers crimp caps for 12–10 AWG and 22–18 AWG wire, as well as long-neck options for 16–14 AWG wire. Compare the product specifications with your wire before selecting a connector, and keep the connection style consistent with your installation plan.
