Metra 25-Pack Uninsulated Butt Connectors – 16-14 Gauge – Car Radio Alarm Wire Terminals

If you’re doing car audio or alarm installs, you know you always run out of the right connectors.

This 25-pack of uninsulated butt connectors from Metra is a solid addition to the toolbox.

They’re sized for 16 to 14 gauge wire—the most common sizes for car stereo and security system wiring.

No insulation means you can crimp and then add your own heat shrink for a clean, waterproof seal.

Part number is UBBC-25, and it’s Metra, so the quality’s decent.

Brand new, still in the pack.

Great for making permanent splices that won’t pull apart.

Use them for speaker wire, power leads, or any 12V accessory connection.

The uninsulated style gives you flexibility to use your own tubing or tape.

If you’re tired of cheap connectors that crush instead of crimp, these Metra ones hold tight.

25 pieces means you’ll have spares for the next job.

Simple, effective, and cheap.
