Overview
A trunk or under-seat subwoofer build is where this Taramps monoblock belongs, with a single channel built to drive a one ohm load. Variable high-pass and low-pass filters, gain and bass boost let you shape the output, and the aluminum body mounts on a surface.
The large power rating is the reason to consider it for a high-output subwoofer system. The limit is the electrical load: it needs heavy power and ground wiring that the listing does not describe, and it is a single channel.
Who it's for
Car audio builders with a matched subwoofer and an upgraded electrical system will use the output and tuning controls. Anyone adding a simple factory-style system should choose a lower-power amplifier.
Pros and cons
- Very high power rating
- Stable at a low impedance
- Variable high-pass and low-pass filters
- Gain and bass boost controls
- Needs heavy wiring and power
- Single channel only
- Wiring kit not described
Performance notes
Output depends on a stable supply voltage and a speaker load that matches the low impedance rating. Filters let you limit the amplifier to the bass range or the full range. Low voltage or thin wiring will cut real output below the headline rating.
