The Timpano TPT-1000.4 is a compact four-channel Class D car amplifier rated at 4x260 watts RMS at 2 ohms and 2x520 watts bridged at 4 ohms. Its small heatsink footprint and 80-90% efficiency suit tight installs and stock electrical systems. It runs full range, so it can drive door speakers and tweeters as well as a subwoofer on bridged channels. Against larger Class AB amps it trades some warmth for size and current draw, and owners rate it highly for output per inch.

Owners rate it 4.9 out of 5 and praise its power for the size and its clean output. Most criticism centers on heat and on the power ratings needing solid electrical support.
This is a compact 4-channel, full-range Class D car audio amplifier for 12-volt systems. It pairs a high-speed MOSFET power supply with transistors in a small heat sink. Its efficiency is 84%, which means less battery draw for the power it delivers.
Two channels can be bridged for more power to a speaker. A protection circuit guards the amp against overheating and against shorts caused by a failed speaker. The frequency response runs from 20Hz to 26kHz.
Built-in crossover filters let you choose a fixed 90Hz high-pass, a fixed 90Hz low-pass, or Flat if you use an external crossover or DSP. A variable gain control sets how much signal comes in from the source. It is not a volume control. Power and speaker wires connect with fork terminals.
