Taramp's TS 400x4 4-Channel 400W RMS Class D Car Amplifier

The Taramp's TS 400x4 is a compact 4-channel Class D car amplifier delivering 400 watts RMS total (100W x 4) with bridging capability, fixed crossover and precise gain control for versatile vehicle audio setups.

Compact yet powerful, the TS 400x4 from Taramp's is built to add clean, reliable power to door speakers, tweeters, midranges and small subwoofers. Its Class D topology keeps heat and weight low while offering enough output to upgrade factory systems or power a modest aftermarket setup. The unit includes short-circuit protection, LED status indicators and straightforward controls so installation and tuning stay simple for DIYers and professionals alike.

How much power does this amplifier actually produce?

The TS 400x4 provides 100 watts RMS per channel into 2 ohms, totaling 400 watts RMS. It supports bridged operation to combine two channels for higher output to a single speaker or subwoofer, giving you flexible power options without a bulky chassis.

• Nominal output: 100W RMS × 4 channels (400W total) at 2Ω
• Bridged mode available for two-channel higher-power loads
• Class D design for efficient power delivery and compact size

What inputs, controls and protections are included?

The amplifier accepts RCA line-level inputs and features a fixed low-pass crossover plus gain control for basic tuning. Protection circuitry includes short-circuit safeguards and an LED indicator to report operating status, helping prevent damage and simplifying troubleshooting.

• RCA inputs for easy connection to head units and processors
• Fixed low-pass crossover at 90Hz (-12dB/8º) and gain control for level matching
• LED indicator and short-circuit protection for reliability

What wiring and installation considerations should I know?

The TS 400x4 is engineered for compact installs; its small footprint and light weight make it easy to mount under seats or behind trim. Use the recommended wire gauges and a 20A fuse to ensure safe operation and stable voltage under load.

• Power cable: 11 AWG recommended for positive/negative leads
• Output wiring: 15 AWG for speaker connections; remote turn-on: 18 AWG
• Fuse/circuit breaker: 20A inline protection required

How does the physical size affect placement and cooling?

With dimensions roughly 5.43" × 1.93" × 4.76" and weighing about 1.32 lb, the TS 400x4 fits tight spaces where larger amps cannot. Its Class D efficiency reduces heat buildup, but allow some airflow and avoid fully enclosed compartments for best long-term reliability.

• Compact footprint fits under seats, in gloveboxes or behind panels
• Lightweight chassis simplifies mounting in small vehicles and golf carts
• Leave clearance for air circulation to maintain thermal performance

Who is this for? The Taramp's TS 400x4 is ideal for drivers who want a space-saving, cost-effective upgrade to factory audio systems, builders of compact car or motorcycle audio setups, and anyone needing a small multichannel amp with bridging options. It suits installations powering door speakers, full-range drivers, tweeters, midranges, and modest subwoofer applications where a simple fixed-crossover amp and durable protective features are desired.
