Taramps TS 400X4-HLI

The Taramps TS 400X4 (HIGH LEVEL INPUT) is a compact 4-channel amplifier designed for a wide range of car audio applications. With a total of 400 watts RMS at 2 ohms, it is ideal for powering front and rear speakers, component systems, coaxial speakers, or—thanks to bridge mode—even smaller subwoofers.

A key advantage of this model is its built-in high-level input. This allows the amplifier to be connected directly to the speaker outputs of a factory radio or OEM multimedia system. When using the high-level input, the TS 400X4 also supports an automatic power-on function, eliminating the need for a separate remote wire with compatible radios. Advanced Speaker Simulation (A.S.S.) further ensures high compatibility with OEM radios that feature speaker diagnostics.

Alternatively, standard RCA inputs are available. To accommodate different speaker configurations, the amplifier features built-in crossovers with FULL, HPF, and LPF modes. HPF and LPF operate at a fixed crossover frequency of 90 Hz.

Thanks to its Class D technology, the TS 400X4 combines high output power with compact dimensions, making it particularly well-suited for installations where space for the amplifier is limited.
