4 CSC684 6x8" 450W Car Audio Speakers Plus 4-Channel Amplifier And Amp Kit

This system pairs four KICKER CSC684 6x8-inch coaxial speakers with a Rockville RXA-F1 4-channel amplifier and an RWK42 wiring kit, giving you everything needed to replace factory speakers and add real power behind them in one order. Each CSC684 uses EVC (Extended Voice Coil) woofer technology and a zero-protrusion PEI tweeter with a neodymium magnet, so the upgrade adds cleaner bass and crisper highs without interfering with the factory grille. The RXA-F1 backs those speakers with 1600W peak output and 400W Dyno-certified RMS power across 4 channels, plus a high-speed MOSFET power supply, studio-grade bipolar transistors, and a fully adjustable 12dB crossover for tuning the sound to the vehicle. Auto-start smart turn-on senses a signal from the head unit and switches the amp on automatically, so there is no separate remote-turn-on wire to run. The RWK42 kit completes the install with a 4-gauge power cable, matching ground wire, two sets of twisted-pair RCA cables, an 80A AGU fuse, and split-loom tubing to protect the run under the hood, plus the terminals and ties needed to finish the job. Instead of sourcing speakers, an amp, and cabling separately, this bundle covers the full chain from head unit to speaker in a single purchase.
