Why Choose This Product?
The ST4.1000D is a starting point for a multi-channel speaker layout, where channel arrangement and output at the actual connected load matter more than a headline maximum-power number. Compare the ratings above with the continuous requirements of the speakers you plan to use. Keeping those decisions together helps avoid buying an amplifier that is powerful on paper but wrong for the installation. For this model, the listed feature set includes Class D amplifier design. Check how that feature fits your intended system rather than substituting specifications from a similar model.
Installation & Compatibility Notes
Match the amplifier to the final impedance of your wired speakers or subwoofers. Compare continuous RMS ratings at that load rather than treating maximum power as continuous output. Plan appropriate power wire, fusing, grounding and ventilation for the installation.
Plan the power and ground paths, circuit protection and mounting location before connecting the amplifier. Leave the controls accessible, protect wiring where it passes through panels and allow ventilation around the chassis. Set input sensitivity to the source signal rather than treating the gain control as extra volume.
Frequently Asked Questions
What is the ST4.1000D’s rms power 4ω?
RMS Power 4Ω: 90W x 4. Use the stated load and channel conditions when matching this model to the rest of the system; a maximum-power figure is not the same measurement.
What is the ST4.1000D’s rms power 2ω?
RMS Power 2Ω: 125W x 4. Use the stated load and channel conditions when matching this model to the rest of the system; a maximum-power figure is not the same measurement.
How should I choose speakers for the ST4.1000D?
Match the amplifier’s documented RMS rating and supported load to the combined speaker wiring. Do not assume a bridged or lower-impedance configuration is supported unless it is explicitly specified for this model.
