Installed on Hyundai i30

Amongst the various components to upgrade a car's sound system, the Esatto Ma-d4 makes the most difference to the sound quality. I am upgrading from an Audison dsp. This is a testament to Esatto's performance. There is a noticeable improvement in sound quality and sound stage. It also brings about a more immersive experience playing back movies on my head unit. The Chinese android head unit that I am using didn't have exactly a decent sound quality. The Esatto dsp completely transforms its mediocre sound quality to that of a higher end unit. The provision for Bluetooth connection is a bonus, allowing a decent Bluetooth music streaming. In addition, there is also an Android app for setting sound parameters with presets. A must have especially for owners of current cars with factory provided head units.

What I like
Significant improvement in sound quality. Android app provides ease of changing sound parameters.

What I do not like
Less affordable that other components in the system.

Installed on Toyota Harrier

In my years of listening to music in the car, I have yet to experience the one that I am experiencing now after upgrading to Esatto DSP into my Harrier. A simple gadget tucked below the passenger seat, it allows me to play lossless audio quality from my phone to the DSP cum amplifier. The surround effects was amazing which I felt like being there where the performance is and the power delivered made the sound stage enormous. Impressive! After the installation, it has at least to me proven that all the positive reviews that I have read is indeed valid. Worth it really! A quantum leap in audio quality over the standard clarion head unit. Highly recommended.

What I like
The sound stage which is immediately immersive. Clean sound. Harness available for my car which meant no cutting!

What I do not like
Could be cheaper but you get what you pay for! Value.

Installed on Kia Stonic

I have changed many cars in the past and upgraded many car audio systems. This time , with the leap of faith , I took the advice from Autoimage to upgrade with a small dsp amplifier . To my surprise, the Esatto MA-D4 DSP amplifier transformed the whole sound system in my Kia with soundstage like a dance club and the power was immense ! Even without a subwoofer, the bass is beyond my expectation! Highly recommended .

Installed on Mercedes-Benz C180

I bought a 2016 Merc C180. Had previously invested in ICE for my driving pleasures.

What I like
Wide soundstage. Very clear highs. All the drivers fit right into the factory locations. There was a need to cut some of the plastic for the tweeter location due the the slightly larger Esatto tweeters. But the result was worth it. PRICE!!

What I do not like
Nothing at this price.

Installed on Kia Sorento

Was done by Ted and his team from AutoImage (the go-to guy in the Sorento group).

What I like
High Clarity and crisp music. Easy connection to phone.

What I do not like
Little pricey (but its branded and reliable. So.. its ok) Full potential of dsp cant be seen using android auto and/or spotify. For best results, play from YouTube.

Installed on Subaru Impreza

Installation was done under 30 mins (plug and play).

What I like
The sound and music quality. No need to cut any wires. I'm still able to use my stock head unit and steering controls.

What I do not like
NIL

Installed on MINI Cooper

Being a fussy consumer , always looking out for a good value DSP and a good installer. A good product also need a good installer. Installed last year after after using it for some time. This small unit able to transform into wider sound spectrum from a bland uninteresting OEM setup. Good upgrades if you are just starting on car audio journey or just trying out wanna out .

What I like
Small unit but able to recreate impressive sound quality and staging
