Overview
A trunk floor or under seat bay is where this compact class D monoblock amplifier is meant to live. It drives one channel from a standard car supply and mounts on a flat surface.
Class D design holds the case small for the power on offer, which helps in tight installs. The listing gives no impedance rating, input types or filter controls, so those details come from the maker before the wiring plan.
Who it's for
Installers building a bass setup around one subwoofer who want a compact amplifier. Anyone driving several speakers, or wanting a documented impedance rating, should look at a multichannel unit.
Pros and cons
- Compact class D design
- Single channel focus
- Surface mount case
- Power rating in the title
- Impedance rating not listed
- RMS and maximum figures conflict
- Filter controls not described
Performance notes
A class D output stage switches rapidly instead of running transistors continuously, which wastes less power as heat and allows the small case. Real output depends on the vehicle supply voltage and on matching the subwoofer load to the amplifier.
