Description ECHO SERIES SPOOL WIRES (FULL ROLL SET) Our Echo series Power / Ground Wire consists of oversized copper clad aluminum (CCA) conductors. Echo wire has been over sized by design to offset the higher resistance of CCA compared to an OFC cable. So, you get equal performance and at sizable savings. CCA overall provides a cost effective solution to most audio systems. Recoil Echo series cable also features an ultra-flex matte PVC jacket that makes it bend to any radius for easy installation
