XMS400D 4 Channel Micro Amplifier (Black)

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.

I used a loopback harness to wire this amp between the radio and speakers on my non-Bose 2020 GMC Canyon. While this amp doesn't put out a crazy amount of power it was more than enough to "wake up" the speakers in my truck and provide a much fuller listening experience. A huge plus is that the lower power requirements for this amp meant I could power it directly off one of the power wires for my radio.

I purchased this small discreet amp with not much expectations but WOW this thing can be tucked away and hidden just about anywhere I wasn't expecting much as Sony has gone in the wrong direction a few years ago in quality hifi equipment but this little brick packs some punch it sounds great and out performs in my opinion and I'm pretty hard to please when it come to audio equipment I hooked it up to a Joying 10.1 Android HU install was easy and didn't have to run a remote wire if you are not going to run a sub and don't want to tear your truck apart to install a bigger amp and just looking to boost a stock HU this is your ticket Very pleased

Stay away, sound it is not good, I ended up returning it, by the Alpine one, which is the best and costs a little more but it's worthy.

Very easy to install, doesn't require a large gauge power or ground and provides really nice sound. It's also tiny. I knew it was small, but pictures don't really show just how small. This amp does not have a gain control, so this is a good option for the car audio novice, it is truly plug and play.

Really cleaned up the sound and I liked how it mounted right behind my existing stereo

Very small and powerful. Fit my needs perfectly in Jeep TJ where passengers airbag used to be.

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.

Easy install

Brilliant little amplifier, posted reasonably quick, brand new as described, happy with my first purchase using Amazon

Installation cost was a sheer waste as whenever we connect this amplifier and switch on the system the audio comes smooth for 2 minutes and then fails.....
