Overview
Taramps makes this amplifier as a small aluminum body with four output channels that can be bridged. High-level inputs with auto turn-on let it follow a factory head unit without a separate remote wire.
The reason to look at it is a four channel layout in a small package that works behind an OEM radio. The limit is that the listing gives no per-channel power split and no included wiring, only a warranty certificate.
Who it's for
A stock-radio car with a tight mounting spot behind a seat or panel is the setting. Anyone planning a competition system or needing wiring in the box should look at a kit instead.
Pros and cons
- Works with OEM high-level inputs
- Auto turn-on from the signal
- Channels can be bridged
- Compact aluminum body
- Per-channel power split not stated
- Wiring kit not included
- One preamp output only
- Surface mount only
Performance notes
Class D switching runs cooler than older linear designs, which matters in a small enclosure. The rated output is stated at a low impedance, so speaker load changes what you actually get. Bridging two channels trades channel count for more power on one speaker.
