AudioQuest's Flat Series speaker cable is built around a Semi-Solid Concentric design. While this is not as transparent as AudioQuest's Solid-Core Conductors, Semi-Solid wire is significantly more resolved than conventional stranded bundle wire.

Optimize the potential of your vehicle's audio system with this Metra BY-SW40 18-gauge speaker wire. The 40-foot length lets you easily connect any aftermarket single-DIN or double-DIN stereo to your vehicle's original factory radio location, and the clear jacket protects against abrasions. This Metra 18-gauge speaker wire is color-coded for reliable matching of negative and positive connections.

24k Gold Plated Durable Design. FosPower’s deadbolt banana plugs are crafted with 24k gold plated connectors to ensure high quality audio and to be corrosion resistant. The closed type design makes it so your speaker wire enters from the rear/back side of the banana plug and then enclosed and sealed by the connector tip. This ensures isolation of the wires and keeps them from making unnecessary contact and shorting out. 6-Leaf Gold Plated Connector. Our deadbolt banana plugs are designed with a 6-leaf gold plated connector to ensure maximum connectivity and sound quality. The 6-leaf design allows for the most secure and maximum range of connectivity with your audio ports on your audio system. No more wires accidentally getting unplugged from your audio system. Easy Installation. No need for soldering, extra accessories or tools needed. Simply strip your wire, insert the wire through the deadbolt banana plug and then twist on the 6-leaf gold plated connector. Save yourself from countless headaches and make your audio system setup experience smoother and easier with our screwless design. Color Coded and Supports Multiple Sizes. FosPower’s deadbolt banana plugs are conveniently color coded with two different colors (red and black) for easier polarity identification. Keep your deadbolt banana plugs and wires organized and forget about those tangled messes. Our deadbolt banana plugs support 20AWG to 8AWG speaker wires.
