Metra's Turbowire speaker harnesses are an essential install component for anyone upgrading to aftermarket speakers. By preserving the factory wiring harness, this adapter protects your vehicle's electrical system and simplifies future speaker changes. Note: Some aftermarket speakers have terminals wider than the included slide-on connectors; widening the connectors or using the terminals supplied with the speakers may be required.
