Running an amplifier power cable through your vehicle’s firewall requires a secure, insulated passage. This Edge Audio firewall grommet protects your wire from sharp metal edges that can cut insulation and create a dangerous short circuit. A must-have for any car audio installation.

2. Water-Tight Compression Seal
The included locking nut tightens down to compress the internal seal around your power wire, creating a water-tight barrier that keeps moisture and engine bay debris out. This secure fit also prevents the cable from shifting or rubbing over time.

3. Fits True-to-Spec Wire Sizes
Designed specifically for [1/0 AWG / 4 AWG / 8 AWG] power cable. The precision-machined opening grips the wire firmly without crushing it, ensuring a clean installation that stays sealed even under vibration.

4. Durable, Corrosion-Resistant Construction
Built from heavy-duty materials that resist corrosion and withstand the harsh under-hood environment. The threaded body and locking nut provide a solid, long-lasting hold through the firewall panel, keeping your wiring safe for the life of your audio system.
