Make speaker-level signal connections

This Rockford Fosgate adapter lets you connect the speaker-level outputs from your car stereo to a compatible amplifier with RCA inputs that will accept a high-level signal. Once you've connected your speaker wires to this adapter, you'll run RCA patch cables (sold separately) from the adapter's female connectors to your amp. Oxygen-free copper wires and platinum-plated connectors resist corrosion and ensure good signal flow. Warranty: 1 year

Crutchfield Customer Review (What's this?)

Awesome quality.

Pros: They worked like a champ. Joined the two negative cables and grounded them then hit the positive wires running to the rear speakers and boom, out comes the sound!!!! Saved me around $60 by going with the pre made adapters. They went in a 2010 Camaro SS.

Cons: Nothing at all.

just wanted i needed

Easy to use and great quality. It actually has a wiring diagram that helps you know what to do during installation. I rejected all others because of this.

Pros: Detailed information. Great quality.
