Alpine R2-S653 6.5" 3-Way & R2-S69 6x9" Coaxial Speaker Bundle

SKU CH-ZTNZ-E1VBC

A bundle pairing 6.5" three-way component speakers with 6x9" coaxial speakers, handling 100 W RMS and reaching 40 kHz

  • TypeSpeaker
  • High-resolution audio up to 40 kHz with magnesium hard-dome tweeters
  • 100 W RMS per pair for clean, powerful output
  • 3-way component design separates woofer, mid-range and tweeter for precise imaging
  • 6 x 9 coaxial speakers add wide-range rear fill without extra mounting depth
  • Die-cast aluminum baskets reduce resonance for tighter bass response

Alpine R2-S653 & R2-S69 Speaker Bundle

This bundle pairs a 6.5-inch three-way component set with a 6x9-inch coaxial pair for a full-range car audio upgrade. The component system separates woofers, mid-range drivers and hard-dome tweeters for precise imaging. The coaxial units combine woofer and tweeter in one frame for simpler rear-fill installation. Both sets use glass-fibre reinforced cones and magnesium tweeters rated to 40 kHz.

100 Watts RMS / 4 Ohm Nominal Impedance

Each speaker set handles 100 watts RMS and presents a 4 ohm load, so the amplifier must deliver clean power at that impedance. The three-way components reach down to 65 Hz with 88 dB sensitivity, while the 6x9 coaxials extend the same low-end response. Matching the amp’s RMS rating to these figures prevents thermal damage and ensures controlled cone movement at high volumes.

Component Woofers Need 63 mm Depth.

The 6.5-inch door woofers require a 135 mm cutout and 63 mm mounting depth, while the separate mid-range units need a 73 mm cutout and 36 mm depth. Tweeters offer flush or surface-mount options with included hardware. The 6x9 coaxials use a composite basket that fits factory 6x9 openings. Verify door cavity clearance and baffle thickness before cutting; the flexible crossover networks mount remotely and add wiring steps.

Questions about this item

What does the 100-watt RMS rating mean for daily listening?

The 100-watt RMS figure is the continuous power each speaker set can handle without damage. Pairing with an amplifier rated near 100 watts per channel at 4 ohms will give clean, undistorted volume at highway speeds.

How does the 4-ohm impedance affect amplifier matching?

Both the 6.5-inch component set and the 6x9 coaxial set present a 4-ohm load. Choose an amplifier stable at 4 ohms per channel; most car stereo amps are, so the speakers will draw the power the amp is rated for at that impedance.

Will the 63-millimetre woofer mounting depth fit my front doors?

The 6.5-inch woofers need 63 millimetres of clear depth behind the mounting plane. Measure from the inner door skin to any obstruction — window mechanism, wiring loom, or door beam — to confirm at least that much space before installing.
