Alpine S2-S68 6x8" Coaxial Speaker Bundle

This bundle pairs Alpine S2-S68 6x8" coaxial speakers with Stinger RKFR5768 Roadkill Fast Rings for 5x7" and 6x8" openings. The speakers are Hi-Res Audio certified and reproduce frequencies up to 40kHz. A pry kit and Alpine coozy are also included. Ideal for drivers replacing factory 6x8" or 5x7" units who want a direct-fit upgrade.

Upgrade From Factory 6x8" or 5x7" Speakers

The kit fits both 6x8" and 5x7" factory locations using the supplied adapter rings. The jump is worth it when the original cones are torn, the tweeters are muted, or the system lacks detail above 73Hz. The 230W peak and 75W RMS ratings give headroom for an aftermarket amplifier. Buyers needing component separation or larger woofers should look elsewhere.

Hi-Res Certified 73Hz–40kHz Frequency Response

The coaxial design integrates a 1" tweeter, so imaging depends on factory mounting height. The poly‑propylene, glass‑fiber and mica cone with H.A.M.R. surround handles 75W RMS continuously. Output below 73Hz rolls off, so a subwoofer is required for full‑range bass. The 40kHz upper limit exceeds standard CD bandwidth but demands a compatible source.

Questions about this item

What size speaker opening does the 6x8" coaxial set fit?

The speakers are built for a 6x8" cut-out and the included Fast Rings cover both 5x7" and 6x8" openings.

How do the Roadkill Fast Rings install and what step is often missed?

The rings bolt to the door metal first; the speaker then mounts to the ring. People often forget to seat the ring gasket before tightening the speaker screws.

When should the H.A.M.R. surround be checked or replaced?

Inspect the surround annually for cracking or loss of elasticity; replace it if the cone moves unevenly or distortion appears at 75 W RMS.
