KICKER LX500.4: The Pinnacle of High-Power SQL Design The KICKER LX-Series 500.4 represents a masterclass in "Sound Quality Loud" (SQL) engineering, designed from the ground up to satisfy the most demanding audiophiles. This 4-channel powerhouse delivers a staggering 125W x 4 at 4Ω, ensuring your mids and highs pierce through with clinical precision and breathtaking authority. Built with a high-efficiency Class-D design, the LX500.4 runs cooler and draws less current, allowing for extended high-volume listening sessions without the risk of thermal shutdown or excessive battery drain. What sets the LX500.4 apart is the revolutionary LX Control Center (LXCC). This wired command module puts real-time diagnostics and precision tuning at your fingertips, featuring battery voltage monitoring, temperature readouts, and clipping indicators. Beyond just power, this amplifier offers unmatched flexibility with FIT+™ technology, which rejects electrical noise and accepts up to 40V signals, making it compatible with virtually any factory or aftermarket head unit. Aesthetic customization meets rugged performance with a reversible center panel and 11 selectable RGB LED accent colors to match your vehicle's interior. Whether you are running a high-end active front stage or bridging the unit to push 450W x 2 into a pair of heavy-duty woofers, the LX500.4 provides the stability and protection features—including gain-match LEDs—needed for a lifetime of premium performance. 51LX5004 Whitepaper PDF TECHNICAL SPECIFICATIONS LX500.4 4-CHANNEL AMPLIFIER PERFORMANCE RMS Power @ 2 ohms Stereo 225W x 4 RMS Power @ 4 ohms Stereo 125W x 4 RMS Power @ 4 ohms Bridged 450W x 2 Dynamic Power 1100 Watts Frequency Response 20 Hz – 20k Hz Signal-to-Noise Ratio >95 dB (a-weighted) Input Sensitivity High Level: 1V–40V / Low Level: 125mV–5V Crossover Slope Variable 12, 18, or 24 dB/octave LX CONTROL CENTER (LXCC) FEATURES DIAGNOSTICS & TUNING INTERFACE Real-Time Monitoring Voltage, Temperature, Protection Status Signal Indicators LED Output Clip Indication Precision Adjustments Gain Trim, Time Delay, Crossover Frequency Crossover Types HP / LP / BP (High, Low, and Bandpass) Cable Length 3.28 feet (1m) integrated DIMENSIONS & DESIGN PHYSICAL SPECIFICATIONS Height 2-3/8 in (6 cm) Width 8-7/16 in (21.4 cm) Length 9-7/16 in (24 cm) Accent Lighting 11 Selectable RGB LED Colors Warranty 2 Years (Authorized Dealer)
