Powerful four-channel upgrade for your car stereo

The BOSS Audio Systems R3004 is a four-channel amplifier designed to deliver real-world volume with clear, controlled sound. It supports 2-ohm stability and up to 1200 watts max, giving you room to grow your system without immediately replacing hardware. The integrated MOSFET power supply helps maximize output efficiency, while the compact build makes it a versatile fit for many vehicles. Whether you’re upgrading a factory setup or building from scratch, this amp provides a strong foundation for better bass, clearer mids, and smoother highs.

With four channels at your disposal, you can power front and rear speakers while leaving room to add a subwoofer later. The R3004’s design emphasizes reliability and ease of installation, making it a compelling option for first-time car audio buyers who want more impact without a steep price tag.

Shape and tailor your sound

Fine tune your system with a fixed high-pass crossover, a variable low-pass crossover, and a variable bass boost. The gain control adjusts the signal from your head unit to the amplifier, helping you achieve clean, balanced levels without distortion. The combination of these features lets you emphasize highs, mids, or bass depending on your music and listening environment.

• Full range operation lets you run speakers and subwoofers from a single amp
• Bridgeable channels provide a simple path to more power for bass or multi speaker setups

Bridge, bass, and driver-friendly controls

The R3004 makes it easy to scale your system as you grow. If you want more impact from bass or more power to your speakers, you can bridge channels to push additional wattage where you want it most. The fixed high-pass crossover focuses on protecting smaller speakers and tweeters, while the full range capability keeps your options open for different configurations and future upgrades. A remote subwoofer control adds another layer of convenience, letting you adjust bass from the driver's seat so you can fine-tune the experience on the go.

• 2 ohm stability offers compatibility with a wide range of speakers and subwoofers
• Class A/B topology blends efficiency with robust current delivery for better dynamics
• Remote subwoofer control enables bass adjustments from the driver seat
