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. Review: Very good at what it does - I got this because I didn't want to fill my trunk full of bulky, heavy, space eating gear. All I was after was a little more kick to the sound of my Sony CDX G1200U I purchased a couple years back and this works very well. It doesn't pick up engine noise or get real hot when used for an hour or more. It will let you know if your original recording has trash in it like hiss or pops because they will be more pronounced, but good clean original CDs or MP3 files sound great. The radio sounds like a radio but better. The installation instructions are easy to follow and it comes with all the cords and plugs you need. If you are looking for a system that will rattle your windows and license plate this isn't it, but it is a Sony product so the quality is there. ## Features - Continuous power output of 45 W per channel (at 4 Ω), Class-D Technology, Compact Design - Built-in LP (low-pass) filter and HP (high-pass) filter, Protection circuit and indicator provided. - High level or low level input connection, Hi-level Sensing Power On ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01FUFE33O | | Best Sellers Rank | #51,802 in Electronics ( See Top 100 in Electronics ) #102 in Car Multichannel Amplifiers | | Brand | Sony | | Built-In Media | 4 Channel amplifier, Harness, screws, mounting tabs, instructions | | Customer Reviews | 4.0 out of 5 stars 134 Reviews | | Item Weight | 1.8 Pounds | | Manufacturer | Sony Mobile Communications, (USA) Inc | | Mfr Part Number | XMS400D | | Model Number | XMS400D | | Unit Count | 1.0 Count | | Warranty Description | 1 year | ## Images ![XMS400D 4 Channel Micro Amplifier (Black) - Image 1](https://m.media-amazon.com/images/I/51g25hspBbL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Little Sony beast *by E***N on October 12, 2025* Ok.
