Product details

Powerful 4-Channel Car Amplifier for Enhanced Sound

The BOSS Audio Riot R2504 delivers up to 1000 Watts max across four channels in a compact chassis. With a robust MOSFET power supply and 2-ohm stability, this Class A/B amplifier is designed to drive both speakers and subwoofers with clarity and punch, making it a practical upgrade for growing systems.

Key specs you can rely on include 250W max per channel at 2 ohms, 125W per channel at 4 ohms, and 500W bridged when two channels are combined. The unit remains fully adjustable through input sensitivity, bass boost, and crossover options to tailor the sound to your vehicle and listening style.

Flexible tuning and easy control

The Riot R2504 offers a variable gain control (signal level from your receiver) and a variable bass boost so you can dial in the exact amount of low end. The fixed high-pass crossover helps focus sound on the front stage, while the low-pass option shapes the bass to taste. A dedicated remote bass control lets you tweak the low end from the driver's seat.

Power, versatility, and growth

Bridgeable design allows you to pair channels for higher output, expanding your system without swapping hardware. This makes it a solid option for first-time buyers seeking more bass, better clarity, and expanded headroom without a steep price tag.

Helpful notes
