The Kicker 46CSS654 is a 6.5-inch component speaker system built for drivers who want a real step up from factory audio. Separate woofers, titanium tweeters, and two-way crossovers give you control over your sound that a coaxial speaker simply can't match.EVC™ Technology for Tighter BassKicker's Extended Voice Coil (EVC™) technology keeps the woofer moving smoothly and accurately, delivering controlled bass response down to 35Hz. The UV-treated poly-foam surround and phase plugs in the woofer cones work together to reduce distortion — so what you hear is cleaner, not just louder.Titanium Tweeters That Reveal the DetailThe 20mm titanium dome tweeters use neodymium magnets to handle high-frequency detail up to 21kHz without harshness. The included 12dB two-way crossover has a three-position tweeter level switch (0, 3, and 6 dB attenuation), so you can dial in the highs to suit your ears and your install.Flexible Tweeter MountingThe 46CSS654 comes with three tweeter mounting options — flush, angled, and surface pods — making it straightforward to place tweeters for accurate imaging regardless of your vehicle's dash or door layout.Worth Knowing Before You BuyThe Kicker 46CSS654 handles 100 watts RMS, so they'll perform at their best paired with an aftermarket amplifier rather than a head unit's built-in power. They also won't replace a subwoofer — the 35Hz low end is solid for a component set, but if deep bass is what you're after, plan to add a sub to the system.
