Timpano Compact 4 Channel TPT500.4 Car Audio Amplifier – 4x 125 Watts at 2 Ohm – Mini Stereo 12 volts Fullrange Class D Amp Bridgeable

Small Footprint Technology! HD Sound Quality!

Timpano amplifiers raises power amplification to a new standard of quality and usability. The new line delivers the most innovative and powerful Brazilian technology in compact full range amplifiers on the market. Loaded with features, it provides an unsurpassed efficiency rate of 80-90% in a compact Class D full range amplifier.

  • COMPACT DESIGN: Digital class D Brazilian technology allows this amplifier to have a small footprint by integrating a high-speed mosfet power supply with top of line transistors to ensure performance in a small heat sink without compromising performance. Dimensions: 3.93″ depth x 5.02″ width x 2″ height
  • POWER: This amplifier is designed to run your stereo system with the power it needs to perform! 500 Watts maximum dynamic RMS power output of 4x 125 Watts at 2 Ohm per channel. Its high efficiency rate of 87% provides more power with less battery consumption.
  • BRIDGEABLE: Double the power output to your speakers by bridging two channels. Minimum impedance of 4 Ohm per bridged channel at output power of 2 x 225 Watts RMS
  • TECHNOLOGY: A smart electronic 2-way protection circuit protects the amp if it gets too hot or if speakers fail causing a short! Focusing in sound quality, a full range response of 10 to 24,000Hz was used to give the best sound reproduction on this tiny amplifier.
  • FEATURES: Heavy Duty 10 Gauge power and speaker wire Inputs. Built-in crossover filters for easy tuning! Choose between a fixed HPF at 90Hz or LPF at 90Hz + 45Hz Bass Boost or just turn it FLAT and use your external crossover or DSP settings. It also includes Variable Gain Control. Level controls are not for adjusting volume. They adjust the amount of signal that is coming into the amplifier from your signal source.

Before Installing:

You must follow the instructions for the product’s installation and connections to guarantee optimal performance. If you have any questions, get in touch with us. Before using the amplifier, always follow these guidelines:

• Make sure the amplifier is switched off before adding or removing any connections. This prevents possible damage to the equipment connected to the amplifier;
• Keep all cables as far away as possible from the ignition cables, electronic injection modules and starter switch since they may cause noise interference;
• Always use 100% Copper cables and good quality connectors. This guarantees the sound’s quality and fidelity;
• To avoid damaging the cables, make sure that they do not touch sharp metal edges. Important: Use a fuse 12 inches away from the battery as a safety precaution

The power rating data is based on equipment from the PRV Audio Group laboratory. Rated power tested with 100Hz to 1KHz sinusoidal signal and THD <= 10%, with resistant load referring to the indicated measurements. The electronic components and the manufacturing process can present manufacturing variations, thus leading to a variation in the measurements made. This amplifier is designed to perform on music applications ( with speakers ), any load test ( resistant  load ) is not recommended.



How to wire speakers in stereo with a common ground 4 channel amplifier design?
In this compact design, both front channels will be connected to the middle terminal. In the middle terminal output, the negative wire from the left side speaker and the positive wire from the right side speaker will be connected together, in the middle output terminal. If you need to run the Front Channels in bridge you will only use the outside terminals for those 2 channels as the positive and negative.
NOTE: In the event that the amplifier stops working, unplug the speakers and turn the equipment back on. If the problem persists, contact Timpano technical support through the online contact form at

Great amp



Cheaper than the 4 speakers I bought (4 ohm, 45watt RMS). Boosts line-level inputs to a decent volume. Not really working hard.

These lil amps are great

Easy to work and sounds great and they are easy to hide

Great Item

Works great
