Review: Great upgrade - This amp works great, I hook it to the old cigarette lighter circuit that is 15amps so no need for extra wiring, clean and powerful sound, easy to install.
Review: Little Sony beast - Ok. Just installed it on a Corolla 2009 non-jbl using the stock radio. I didnt want to replace the radio as i am not into loud music, but my speakers were damaged so i had to replace then and wanted to make use of their full potential. The amp does its job very well. I am very impressed. It fits behind the radio perfectly. It is powerful enough to output good sound without blasting, but im sure it can. Well worth the money. Had to play with the wiring but i was able to install with harnesses without cutting any of the original car wires, just the harnesses.

## Questions & Answers

**Q: does this have to be powered from the battery or can it be powered from head unit?**
A: Needs external power (not from head unit) from battery. I wired mine to fuse block.

**Q: will this amp handle 350 watt speakers or do i need a higher amp?**
A: 350 watt speakers probably have lower sensitivity which means a mismatch for this low wattage amp.  Search and read about speaker sensitivity which is measured in dB.

**Q: What wires are required for a 2016 Jeep Grand Cherokee with base six speaker radio?**
A: don't know I ran all new wires for four speaker system.

**Q: Is the outside of this amp made of aluminum?**
A: I believe it is thin steel plate.

### ⭐⭐⭐⭐⭐ Excellent micro amp!
*by C***K on April 26, 2021*

Bought a used 2010 Honda Accord and wanted to upgrade the factory stereo. Installed this amp inside the dash behind a new Sony head unit. The small size makes it easy to install. Also installed dedicated 12 gauge power directly from the battery. Matched to new Kicker speakers front and rear. This amp increases dynamic range and punch and around double the output over just the head unit. Amp does not get warm even when pushed hard. Unit appears high quality and solidly built.
