The result is a powerful amplifier compact enough for installing under normal car seats. Special IC patterns for audio use were applied for quality sound. ✹Other Main Features Total Harmonic Distortion (%) Under front seat In car trunk 0. 0001 0. 1 Output Voltage Vo (Vrms) 0. 5 1 5 10 - Gold-Plated Block Terminal (45°Angle Mount) * Power - 4AWG * Speaker Out - 8AWG - Variable Bass Boost (0-18dB) - Input RCA Terminal - Output RCA Terminal (Pass Through) - SYNC Terminal x 1 Optional Bass Boost Remote Control Standalone setup Cascade stacking ✹Adjustable Plate The plate can be attached in 4 ways to give the best looks to match your setting.
