Features
Woofer Mounting: The speaker baskets have multiple mounting holes and are designed to fit a standard 3-hole 6½" applications and Ford's 4-hole 6½" application. With the extended mounting "ears" around the perimeter of the frame, they also fit many 6¾" applications, but a speaker baffle should be used to seal the inner ring of screw holes. Kicker also makes a dedicated 6¾" speaker in this series (item number 20651KSS67) that is often a better fit for those applications. Adapter brackets are also included that are compatible with other factory speaker applications. Please enter your vehicle information to confirm fit.
Tweeter Mounting Options: The tweeters include brackets to allow multiple mounting configurations; flush-mount, angle-mount, and surface-mount. The surface mount pods are mounted to a threaded, hollow shaft and have a ball-and-socket joint, so they can be turned in any direction, and angled to approximately 40˚.
Tweeter Dimensions:
| Flush | Angle | Surface | |
|---|---|---|---|
| Mounting Height | 0.25" | 0.625" | 3.15" |
| Mounting Depth | 0.6" | 0.65" | 0.75" |
| Frame Diameter | 2.045" | 2.1" | 2.3" x 1.9" |
| Cutout Diameter | 1.662" | 1.787" | 0.475" |
Coaxial Tweeter Mount: In addition to standard tweeter mounting options, the included tweeter mounting posts let you mount the tweeters directly to the center of the woofers, giving you a standard coaxial speaker. The tweeter can be angled up to 12° when coaxially mounted. When the tweeter is attached to the woofer the mounting height increases to 1.078" (top mount) and the tweeter protrusion increases to 0.72" (bottom mount).
Crossovers: The component system includes 12 dB/octave passive crossovers for the tweeters. (Both the woofers and tweeters are wired through the crossovers, but only the tweeters are filtered.) The crossover point is 4,000 Hz. A switch on each crossover allows you to adjust the tweeter output; 0 dB, +4.5 dB, or +9 dB. Each crossover has input and output wires are attached; the 34" woofer outputs have quick slides that connect directly to the woofer terminals and the 32" tweeter outputs have quick slides that mate to the terminals on the wire attached to the tweeters. The 34" input wires are not terminated. The crossovers' dimensions are:
- Length: 4"
- Width: 2⅞"
- Height: 1⅛"
The Kicker KSS650 replaces these items:
- 1" silk dome tweeter with four mounting options
- handles up to 125 watts RMS (250 watts peak power)
- can be installed as separate components or as 2-way speakers

Very happy with this product. Great quality sound, especially when paired with the Kicker Key Amp! The mid-range bass is sooooo much better than stock.
