Powerbass ASA3700.5 — 5-Channel Class AB Vehicle Audio Amplifier (11.4 oz)

Powerbass ASA3700.5 is a compact 5-channel Class AB amplifier for vehicle audio systems (11.4 oz). Its reduced footprint allows installation in tighter spaces while still powering multiple speaker pairs via the 5 x audio channels. The integrated MOSFET power supply improves power efficiency and helps protect wiring during high-voltage transfers. Class AB topology delivers clear, high-quality sound with minimal distortion. Thermal management is upgraded with a redesigned heatsink that includes more extruded fins for better heat dissipation.
