Bring JBL’s concert-style energy to your daily drive. The Stage2 634 uses a durable polypropylene woofer for punchy low-end and a PEI balanced-dome tweeter for crisp, smooth highs. A high-efficiency design (91 dB) means lively sound even from factory head units, and the slim JBL frame is engineered to drop into most 6.5" factory openings without trimming. Rated 40 W RMS / 250 W peak at 4 ohms, these 3-way coaxials are the smart, budget-friendly refresh for tired OEM speakers. Order now and enjoy clearer, more dynamic sound on every journey.

(Note: The “500W total power” line found in some listings is marketing; the verified rating is 250 W peak.)
