The Pioneer GM-A3702 is a versatile 2-channel bridgeable amplifier designed to enhance car audio systems with improved power and clarity. Delivering 60W RMS per channel at 4Ω, or up to 190W RMS in bridged mode for subwoofers, it provides dynamic sound reinforcement with a maximum peak power of 500W.
Built on a Class AB design, the GM-A3702 balances efficiency with high-quality audio reproduction. It supports both 2Ω and 4Ω speakers, making it compatible with a wide range of setups. The inclusion of speaker-level inputs allows seamless connection to factory-installed head units without pre-amplified outputs.
For audio customization, the amplifier features a selectable low-pass filter (LPF) with an 80 Hz cutoff frequency and a 12 dB/octave slope, optimizing bass response. Its compact design with a one-body heat sink ensures efficient cooling and reliable performance.
