Sky High Car Audio Waterproof Grommets – Car Audio Cable Pass-Throughs
Sold by AudioSellerz.com

Keep your wiring clean, protected, and sealed with Sky High Car Audio Waterproof Grommets. These compression-style cable glands are perfect for running power, ground, and signal wires through firewalls, amp racks, battery trays, subwoofer enclosures, and marine/UTV panels without letting in water, dust, or debris.

Each gland uses a locking nut on the back side of the panel plus an internal rubber compression grommet that tightens down around the cable jacket, creating a secure, waterproof, and vibration-safe pass-through. The low-profile black finish keeps everything looking clean and professional in any build.

Available sizes are designed to fit common Sky High Car Audio cable, including 8 gauge, 4 gauge, 1/0, and 2/0 wire (OFC or CCA), making these grommets a perfect match for serious car audio power and ground runs.
