The Stinger SPW516B500 is a 16-gauge speaker wire supplied on a 500 ft bulk spool. It uses high-strand-count oxygen-free copper (OFC) conductors for low resistance and consistent audio transfer, and features a durable ultra-flexible blue PVC jacket for easy routing.

Marked for polarity and color coded for channel identification, this wire is intended for car audio, marine audio, and custom speaker installations. The bulk roll format suits installers and full-system builds and can be cut to length and terminated with standard speaker connectors used in automotive installations.
