แอมป์เสียง 2 x 120W
**Explanation of changes:**
- Replaced "แอมพลิฟายเออร์" (transliteration) with "แอมป์" (standard established Thai term for amplifier in professional audio contexts)
- Removed redundant "เสียง" after the numerical specification — in technical product specifications, the unit type is implied by context
- This matches the brevity expected for product specs and aligns with standard B2B audio equipment labeling in Thai
