Product information

Description

Infinity 3004A is a 4-channel car amplifier with a 300W total power rating designed to increase the output and clarity of vehicle audio systems. The compact chassis fits typical car installations and provides stable amplification for driving multiple speakers or bridged pairs. Built to integrate with factory or aftermarket head units, this amplifier supports powering front and rear speakers as well as bridging two channels to feed a subwoofer for added low-frequency impact.

Advantages

The amplifier delivers consistent power across four channels to improve volume headroom and reduce distortion compared with low-power onboard systems. Its design allows flexible wiring configurations, including stereo and bridged modes, enabling use with a variety of speaker setups. The unit offers thermal and short-circuit protection to maintain reliable operation in automotive environments and a compact footprint that eases mounting in trunks, under seats, or behind panels.

Suitable for

Upgrading factory car audio systems to achieve higher volume and cleaner sound
Powering both front and rear full-range speakers in a vehicle
Bridging two channels to drive a subwoofer for deeper bass
Small to mid-size vehicles where a compact 4-channel amplifier is required

Key specifications

Channels: 4-channel amplifier configuration
Total power rating: 300 watts (total across channels)
Mounting: compact chassis suitable for under-seat, trunk, or behind-panel installation
Modes: stereo operation and bridged channel capability for subwoofer use
Protection features: thermal and short-circuit protection for automotive use

How to use

Install the amplifier on a solid surface with adequate ventilation and run power and ground wiring according to standard automotive audio practices. Connect the amplifier inputs to the head unit’s preamp outputs using quality RCA or speaker-level adapters as needed, and wire speaker outputs to the vehicle speakers or bridged outputs to a subwoofer when higher bass output is required. Adjust gain and crossover settings on the amplifier to match the sensitivity and frequency response of the connected speakers, and verify all connections before powering the system.

Usage recommendations

Use appropriately gauged power and ground cables, ensure a reliable chassis ground, and fuse the power line near the battery to protect the vehicle and amplifier. When bridging channels for a subwoofer, confirm impedance compatibility between amplifier and speaker to avoid overload. Regularly check mounting and wiring for secure connections after extended use.
