Car audio versterker Pioneer GM-A5702 A/B 480W 2.0 kanalen

The Pioneer GM-A5702 A/B 2.0-channel car audio amplifier provides compact, high-performance amplification for in-vehicle sound systems. Designed to deliver clear power and flexible control, this amp supports RCA connectivity, speaker-level input sensing, and a compact chassis (356 mm × 215 mm × 60 mm) suitable for most installations. It operates from a 14.4 V DC supply with a maximum current of 36 A and weighs 2.22 kg.

Advantages

The GM-A5702 offers adjustable bass boost (0/6/12 dB steps) and a variable low-pass filter adjustable from 40 Hz to 500 Hz for tailoring subwoofer response. It combines reduced size with improved power handling compared to previous models and features automatic input signal sensing that switches between RCA and speaker-level inputs and turns the amplifier on in sync with the receiver.

Suitable for

• Improving factory audio systems with an external 2-channel amplifier
• Driving small subwoofers or full-range speakers in compact car installations
• Installations requiring RCA or speaker-level inputs (OEM head units)

How to use

Mount the amplifier in a well-ventilated location using the compact footprint to fit available space. Connect to the vehicle electrical system following the manufacturer's recommended wiring practices (use appropriate gauge power, ground, and remote turn-on wiring). For input, connect RCA cables from the head unit when available or use speaker-level inputs from an OEM receiver; the amplifier will automatically detect and select the proper input. Adjust the low-pass filter and bass boost to match your speakers or subwoofer and listening preferences, starting with neutral settings and making gradual changes while listening at moderate volume.

Recommendations

For reliable operation and optimal sound quality, use proper fuse protection on the power line, secure all wiring connections, and allow adequate ventilation around the amplifier. When integrating with factory head units, use the speaker-level input sensing to avoid additional signal converters.
