MASSIVE AUDIO BLADE X BPX 8004 (Full Range SQ 4-Channel Amplifier)
Power up your car's complete acoustic setup with the Massive Audio BLADE X BPX 8004 Full Range SQ 4-Channel Car Amplifier. Engineered in the USA by Massive Audio under their high-fidelity Sound Quality (SQ) line, the BPX 8004 delivers 800 Watts of dynamic peak power (200W × 4), offering clean amplification for front components, rear coaxials, or a bridged subwoofer combination.
Designed with an integrated OEM high-level line converter that accepts up to 9V speaker inputs, the Massive Audio BPX 8004 taps directly into factory touchscreen stereos or aftermarket Android head units without requiring external hi-low converters. Its compact, heat-dissipating aluminum chassis fits discreetly beneath front seats or inside boot compartments across popular Indian cars including Thar, Thar Roxx, Scorpio-N, Creta, Brezza, and Fortuner.
Key Features & Performance Highlights
800W Peak / Clean SQ Continuous Output: Delivers 200W × 4 peak output and 60W RMS × 4 @ 4 Ohms (or 2-Ohm stereo stable) with ultra-low distortion (<0.1% THD).
Built-in OEM Line Converter with Auto Turn-On: Features auto-sensing high-level speaker inputs with up to 9V signal acceptance, automatically turning the amplifier on without needing a separate remote trigger wire from the head unit.
Full MOSFET Power Supply & Mil-Spec PCB: Built using high-grade switching MOSFETs and military-grade surface-mount components (SMD) on a noise-canceling circuit board for clean signal reproduction.
Custom Frequency Crossovers & Bass Boost: Equipped with independent High-Pass (HPF), Low-Pass (LPF), and 0dB to 12dB bass boost controls to tune component tweeters and mid-bass drivers with pinpoint precision.
Next-Gen 5-Way Protection Circuitry: Built-in safeguards protect against thermal overload, short circuits, reverse polarity, and clipping voltage.
