Infinity Marine 7005A — 5-Channel Class AB+D Boat Amplifier with Bass Boost & Remote Bass Control

Built to fit into tight installations, the Infinity marine 3004A uses a compact chassis so it can be mounted in more locations on a boat where space is limited. It accepts both speaker-level and low-level inputs, making it compatible with factory head units as well as aftermarket marine stereos. The amp includes bass boost with remote bass control for on-the-fly low-end adjustment. Unlike many competitors in its price range, the marine 3004A offers variable electronic crossover circuits to fine-tune system response and optimize performance. Its Balanced Differential Inputs minimize noise and distortion even at high output, and they greatly reduce vulnerability to line-induced, radiated engine noise. Input sensitivity is adjustable depending on the input type: with low-level inputs the control ranges from 200mVrms to 4Vrms, while with high-level inputs it covers 1Vrms to 22Vrms.
