4-gauge firewall bushing
Item # 211FB4 | MFR # FB4

Our take on the StreetWires FB4 by Crutchfield's Ken Nail
Keep water out when you run power cable through your car's firewall. The StreetWires FB4 firewall bushing protects your 4-gauge power cable from wear and chafing, and provides a watertight seal when it's tightened down. Lifetime warranty.
For a clean professional installation this product is great. Requires cutting of the firewall but if you have the right tools and the skills, it is no problem. Highly recommended.
