TELUNSHI A125.4 | 200W×4 Real RMS | Bridgeable | High Separation Low Distortion | Designed for B2B Bulk Orders

 ✅ 1. High Power — One Amp for the Whole System

The A125.4 delivers 125W×4 @4Ω and 200W×4 @2Ω, with 300W×2 @4Ω in bridged mode. One amplifier drives front/rear speakers while bridging a pair for subwoofer duty — reducing installation costs and improving system integration efficiency.

 ✅ 2. Class AB Amplification — Warm, Natural Sound Quality

Class AB topology combines the fidelity of Class A with the efficiency of Class B. Rich midrange, sweet vocals, and punchy bass with musical warmth. Perfect for sound quality (SQ) focused systems — your end customers will fall in love with the sound. Better sound = better reviews = repeat business for your shop.

 ✅ 3. High Channel Separation — Precision Soundstage

With ≥60dB channel separation, left and right signals remain perfectly isolated. Precise imaging, clear instrument separation, and a wide soundstage — this is critical for audiophiles and a key differentiator from budget amplifiers.

 ✅ 4. Flexible System Configurations for Various Vehicle Types

- 4-Channel Full-Range Mode: Drive front and rear speakers for full-car stereo upgrades.

- 3-Channel Mode: Two channels for front speakers, two bridged for subwoofer.

- 2-Channel Bridged Mode: Bridge all four channels into two high-power outputs for performance component speakers.

One amplifier supports multiple setup configurations — reduce inventory complexity.

 ✅ 5. Wide Input Sensitivity — Universal Compatibility

Input sensitivity ranges from 250mV to 2V, compatible with both OEM head unit high-level outputs and aftermarket low-level outputs. No additional adapters needed for most sources — lower installation barriers for your installers.
