Infinity Kappa 603CF | Infinity Kappa 63XF | Component Speakers & Coaxial Speakers

Selling a complete set of 6.5” Infinity Kappa speakers: Kappa 603CF 2-way component system (front) and Kappa 63XF 2-way coaxial system (rear). These retail together for over $560 plus tax, so my price of $350 firm for both sets saves you well over $200. This is the ultimate drop-in 4-speaker upgrade for any vehicle accepting standard 6.5” speakers. Used for only about 4 months in my previous vehicle before trading it in. They were fed clean, unclipped power and treated with care. Main Package Specs & Features 1.
