American Bass Biker Rebel Bundle — 2x Biker 6x9" Midrange + VFL Rebel REBEL-900.4 Amplifier

The loudest mids in the Biker Series, front and center. The Biker Rebel Bundle pairs two American Bass Biker Series 6x9" midrange speakers — the highest-sensitivity driver in the lineup — with the VFL REBEL-900.4 amplifier, for maximum SPL per watt in a low-profile enclosure footprint. What's In This Bundle QTY Component SKU Key Spec 2× Biker Series 6x9" Midrange Speaker BIKER-6.9-MR 400W RMS | 4Ω | Carbon Fiber Cone 1× VFL REBEL-900.4 Amplifier REBEL-900.4 150W x4 @ 4Ω | Class D 4-Channel System Specifications Speaker Configuration Dual 6x9", 2 channels dedicated (2 channels free for tweeters or rear fill) Speaker RMS Each 400W RMS / 800W Max Amp Power to Speakers 150W RMS per channel @ 4Ω Sensitivity 96.5 dB — highest in the Biker Series Frequency Response 70 Hz – 18 kHz Cone / Surround Carbon fiber cone, weatherproof rubber surround Recommended Mounting Standard 6x9 motorcycle enclosures, fairing lowers, custom bag lids, trunk pods (8.6" cutout, 3.5" mounting depth) Install Difficulty Beginner–Intermediate Installation Notes Amp delivers 150W into each 400W-rated driver — a safe, clean headroom margin that won't stress the speakers even at full throttle. REBEL-900.4 is a 4-channel amp: run 2 channels to this pair of 6x9"s and reserve the other 2 for tweeters or a rear pair. Highest sensitivity in the Biker Series means more SPL from the same 150W than any other size in the line — the pick for group rides and highway speed. Both speakers are sealed-back and weatherproofed for open-air motorcycle mounting — no additional weatherproofing needed at the driver. Route and seal all wiring at fairing/saddlebag entry points to keep water out of the amp bay.
