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

This bundle gives all four doors a matching upgrade: the Kicker CXA360.4 four-channel Class A/B amplifier powering two pairs of Rockville RV6.3A 6.5" 3-way speakers. 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 to shape the sound, and it accepts a 40-volt speaker-level input so it wires straight to a factory radio.

Each RV6.3A pairing rates 750W peak and a CEA-certified 140W RMS, meaning the number on the box is verified rather than inflated. A polypropylene woofer and flex-motion butyl rubber surround handle bass and mids, while a 1.2" PEI dome tweeter and a 0.6" super tweeter add clear highs, backed by a wide 34Hz to 20,000Hz frequency response. A shallow mount depth around 2.1" lets these speakers drop into roughly 97% of factory 6.5" locations without extra spacers, and because the CEA rating on both the amp and the speakers is independently verified, the two are guaranteed to be a compatible match rather than a guess.
