The peak output power data comes from new product data provided by Texas Instruments in the United States. This data is obtained in a specific, ideal state with TDH=10% 1kHz. According to the above table, the higher the input voltage, the higher the output power; The lower the speaker impedance, the higher the output power. If you want to achieve good power output, a power adapter of 24V 36V/5-10A or above is a recommended choice.

Review: Would buy again - Powered off of my 24v lifepo4 battery in my semi truck. Pushes the highs at 2ohm and a kicker comp 10 150w rms 4ohm real nice. Sub is in passenger floor in front of seat, can feel and hear the bass very nicely. I will probably upgrade to the metal encased version in due time, but works good for me.
Review: No complaints - Worked great till I upgraded my amp

### ⭐⭐⭐⭐⭐ Would buy again
*by J***R on September 2, 2025*

### ⭐⭐⭐⭐⭐ No complaints

Worked great till I upgraded my amp

### ⭐⭐⭐⭐ Nice, versatile audio amplifier that's a jack of all trades
*by W***G on May 23, 2026*

This is a very clean-sounding, capable amplifier. I'm impressed with the amount of power it can handle, and all the features that come with it for about one-third to one-half the cost of a commercially available amp with similar features. It's goo, but there are some things that are not included that would make it great. Pros * Good, clean power. Very low noise, unless you introduce it yourself from a ground loop or similar power issue. * Takes a wide-range of input power. I started using a Lenovo laptop 19v 5 amp, and then bought a new 36v 5 amp. For my setup, there was practically no difference. * Separate controls/output for subwoofers. This jacks the price in the commercial options to the $150+ category. * Lots of input options, although I think most will use the 3.5 mm audio cable or Bluetooth. * Customizable - if you have a 3D printer, you can make it look like anything you want. Cons * Big "pop" sounds when you turn it on or off. No power on/power off protection/relay to overcome the big capacitor discharges. You can fix this with a $13 board off Amazon (https://www.amazon.com/dp/B0DP9CLBMF?ref=ppx_yo2ov_dt_b_fed_asin_title), but it's an extra cost with extra skill most might not want to take on to play their music. * No high-def audio codecs with Bluetooth. The app is pretty cool, though, if you want a custom name for your Bluetooth connection. I'm using it to drive my home entertainment center, from TV to DVD to PC and streaming music and just love it.
