This Kicker four-channel, K-series interconnect is 6 meters long and features split-pin RCAs with silver-tinned, OFC wire for superior bass response and signal clarity. The single, 4 channel RCA cable is less expensive and easier to install than running two, two-channel cables. The K-series interconnects offer great sound quality at a more competitive price than the Q-series. The Q-series offer additional shielding for the true, audiophile quality sound.
