Taramps TS 400x4 2 Ohms Multichannel Amplifier - Compact 400W

In this review the Taramps TS 400x4 is examined as a compact, powerful option for drivers who need a versatile multichannel amp without extra bulk. The bottom line: this amplifier is best for car audio enthusiasts who want reliable 400 Watts RMS total power with bridged flexibility and small physical footprint. It stands out because it delivers four clean channels at 100 Watts RMS each into 2 ohms, includes automatic high-level input activation, and fits tight installations where size and value matter.

Key Features

• 400 Watts RMS Total: Delivers 100 Watts RMS per channel at 2 ohms, providing headroom to drive multiple door speakers or a compact system with confidence.
• Bridged Flexibility: Supports bridged connections so users can combine channels for higher power to a subwoofer or a larger driver without swapping amplifiers.
• Fixed Crossover: Includes fixed low-pass and high-pass crossovers at 90Hz (-12dB/8a), simplifying integration with speakers and subs for clearer frequency separation.
• High-Level Input with Auto Turn-On: Accepts speaker-level signals and activates automatically, which eases installation in factory systems that lack RCA preouts.
• Compact Size: At roughly 5.43in x 1.93in x 5.16in and 1.43 lbs, the amplifier fits tight locations such as under seats or behind panels while still offering MOSFET power delivery.

Who It's For

The TS 400x4 is ideal for car owners upgrading door speakers, adding a small sub, or outfitting nontraditional vehicles such as golf cars and motorcycles where space is limited and efficient power is required. Its automatic high-level input and fixed crossover make it a practical choice for installers who want straightforward wiring and reliable performance.

Owners seeking advanced tuning controls, variable crossovers, or much higher dedicated subwoofer power should look elsewhere; this model targets compact, full-range systems and value-conscious builds rather than high-end, highly configurable setups.

Pros & Cons

Pros

• High output for size: 100 Watts RMS per channel gives strong performance in a compact amplifier.
• Versatile inputs: automatic high-level input makes it easy to install with factory head units.
• Built-in crossover and gain control simplify setup for a range of speakers and subs.

Cons

• Fixed crossover frequencies limit fine tuning compared with models that offer adjustable slopes and cutoffs.

Frequently Asked Questions

Can this amp drive four speakers at once?
Yes, it provides four channels at 100 Watts RMS each into 2 ohms, suitable for driving four door speakers or a mix of drivers.

Does it need an RCA output on the head unit?
No, the automatic high-level input allows the amplifier to turn on and accept speaker-level signals from factory radios without RCA preouts.

Are the crossover settings adjustable?
No, the amplifier uses fixed high-pass and low-pass crossovers at 90Hz (-12dB/8a), which simplifies setup but does not allow variable tuning.
