About the Kicker 40CSS684
It's time for an upgrade
It's time for an upgrade
Upgrading the old factory speakers in your car will give you a huge bump in sound quality, and Kicker designed CS Series speakers to get your sound system rockin' without breaking the bank. You'll enjoy your music even more when you hear all the details that your muddy-sounding factory speakers couldn't begin to reproduce.
Bring on the treble and the bass
Kicker's 40CSS684 component speaker set provides low-end from a tough 6"x8" polypropylene woofer, with a polyester foam surround that will stay strong for years to come. The separate 3/4" titanium dome tweeter takes care of the vocal and instrumental details that'll really bring your music to life. The outboard crossover network allows you to pick from three different tweeter level settings so you'll get balanced sound wherever you're sitting.
Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Features
Polypropylene Woofer Cones: The Kicker CS-series speakers feature durable polypropylene woofer cones, resistant to the moisture and temperature extremes found in automotive applications.
Woofer Mounting Applications: While Kicker describes this speaker as a 6x8, it also fits many 5x7 applications. Please check the Crutchfield Vehicle Selector to confirm fit.
Ribbed Polyester Foam Surrounds: The ribbed polyester foam surrounds allow extended cone excursion for additional bass output and higher SPL.
Tweeter Mounting Options: The tweeters come with brackets to allow multiple mounting configurations: flush-mounted, angled flush-mounted (approximately 10°), and angled surface-mounted (approximately 15°).

Crossovers: The component system includes passive 2-way crossover networks for a seamless transition between the woofers and tweeters. The slope is 12dB per octave (both high pass and low pass) and the crossover point is 4000 Hz. A switch on each crossover allows you to set the tweeter output; 0 dB, +3 dB, or +6 dB. The crossovers' input and output wires are attached; the woofer output has quick slide terminals that connect directly to the woofer and the tweeter output has bullet terminals that mate to the terminals on the tweeter wires. The crossovers' dimensions are:

Excellent speakers and a wonderful upgrade from factory. '06 F250 the tweeters won't flush mount in the A pillar with the way Ford built the dash, so I surface mounted them towards the top over the dash. Sound great!! The 6x8s fit right into the same location.
