Overview
Taramps designs this model as a compact car audio amplifier with four channels and RCA inputs. The aluminum housing mounts on a surface, and two channels can be bridged for a higher-power output. A Class D design holds the body size down.
A small chassis and four channels are the reason to look at it for a door speaker setup or a front and rear system in a tight install. The limit is data: crossover options, fuse size and wiring needs are not itemized.
Who it's for
Car audio installers upgrading factory speakers with an external amplifier will use the multichannel layout. People planning a single high-power subwoofer channel should look for a monoblock.
Pros and cons
- Four channels in a small body
- Two channels can be bridged
- Class D design
- Crossover details not given
- Fuse size not listed
- Wiring needs not itemized
Performance notes
Class D switching wastes less power as heat than older linear designs, which is why the chassis stays small. Bridging two channels combines them into one higher-power output, and the load impedance matters. Output depends on a healthy supply voltage, so wiring gauge and ground quality matter.
