46CXA3604T CXA360.4 360w RMS 4-Channel Car Amplifier+6.5"+4x6" Speakers

This bundle is built for a mixed front-and-rear layout: the Kicker CXA360.4 four-channel Class A/B amplifier powering a pair of Rockville RV6.3A 6.5" 3-way speakers up front and a pair of Rockville RV46.3A 4x6" 3-way speakers in the rear. The CXA360.4 delivers 65W RMS per channel at 4 ohms or 90W RMS per channel at 2 ohms, with a variable 12dB crossover and KickEQ bass boost of up to 6dB, and it accepts a 40-volt speaker-level input so it wires straight to a factory radio.

The RV6.3A pair is CEA-certified at 140W RMS with 750W peak and a wide 34Hz to 20,000Hz frequency response, suited to a larger factory front opening, while the RV46.3A pair is CEA-certified at 70W RMS with 500W peak, sized for a 4x6" rear deck or door location. Both use a polypropylene woofer, flex-motion butyl rubber surround, and a PEI dome tweeter with a 0.6" super tweeter, and both share a shallow mount depth that fits roughly 97% of factory openings. Matching two different speaker sizes to their factory locations, both powered by one CEA-rated amp, avoids the mismatch that comes from forcing a single speaker size into openings it was not built for.
