Overview

The Taramp's TS 400x4 is a compact, white multichannel car amplifier built for flexible, multi‑speaker setups. Delivering 400 Watts RMS at 2 Ohms, it provides four independent channels with a practical balance of power and efficiency.

Power and performance

Each of the four channels is designed to produce strong, clean output, giving you the option to run door speakers, full-range drivers, or mid‑range/tweet combinations. When you bridge channels, you gain higher output for a subwoofer or a larger speaker load, expanding the ways you can shape your sound.

• 4 channels with 100 Watts RMS per channel for a total of 400 Watts RMS
• 2 Ohm capable, enabling flexible speaker configurations
• Bridged operation for focused bass or higher‑power dedicated channels

Fixed crossovers and tonal control

A built‑in fixed crossover system helps you shape the sound at the source. The unit provides a fixed low‑pass and high‑pass crossover at a selection that works with many car audio layouts, helping you reduce unwanted frequencies and improve overall clarity.

• Fixed high‑pass crossover for the upper range
• Fixed low‑pass crossover to manage bass energy

Connectivity and activation
