Processor sound for Ford Mustang Cabrio instead of the standard one


It is not the first time that a car from another city in Ukraine has been brought to us in Kyiv to improve the sound. This time, a snow-white Ford Mustang Cabrio rushed to us from the blue sea shores of Odessa.

The owner of this horse wanted to significantly improve the sound, the standard/factory audio system, of course, did not suit him. By the way, do you know how to understand that the sound in your car is, to put it mildly, not very good? The simplest thing is to understand – do you experience strong emotions from your favorite tracks as you could experience them at a concert? In most cases, the standard sound is not able to evoke emotions, and why listen to music if not for them?
In general, we were entrusted with the car because we had already worked with exactly the same one and we know for sure how to make the music sound.
AUDIO SYSTEM CONFIGURATION
- Source – factory HU. But there will be an alternative – a Bluetooth module in the processor, with which we can send a signal from the phone directly to the processor – thus simultaneously expanding the functionality of the entire system and improving the sound quality.
- The processor in this case is Helix.
- For the front, we chose a three-band Hertz MPK 163.3 set (you can combine two sets of Hertz MPK 165.3 + Hertz MP 70.3). The standard places of the Ford Mustang imply the possibility of installing six speakers in the front. Of course, we took advantage of this opportunity.
- Audison APX 6.5 was added to the rear exclusively for sound reinforcement and volume.
- The subwoofer in this project turned out to be magical both in sound and in design. We made a custom design with a 19-liter case for the Hertz MP 250 D2.3 speaker
- And the amplifier for the sub we have is GroundZero Mini Two
- Naturally, the doors were treated well – good audio preparation was made for the midbass. Plus, the bottom and trunk were treated with sound insulation.

Installing tweeters in Ford Mustang
We installed the tweeters, as well as all eight speakers in this car, in their standard places. The tweeters from the factory were installed in the racks, and that’s where we installed the Hertz tweeters:



Hertz MP 70.3 midrange speakers in Ford Mustang
Traditionally, we compare factory speakers with new ones (when we don’t forget to take a photo, of course). As usual, the comparison is not in favor of the factory speakers.
In this case, there was one big advantage to the standard Ford Mustang center hubs – we were able to use their spacer rings, into which the Hertz MP 70.3 fit like a glove.







Midbass for Ford Mustang
Midbass speakers in the doors in their regular places. Actually, that’s what the whole story is about) It can be added that the bottom of the car was treated at the same time. High-quality noise insulation and top speakers are some of the main components of good sound.



Rear Sound System for Ford Mustang
At the rear, exclusively for the sound volume, we added the Audison APX 6.5 coaxial speakers that we have tested in this role. We used the standard places for installation. We did not have to rework the places for the speakers, we used the factory potential to the maximum, only slightly modifying it:


Comparing a factory speaker with a new one is our tradition, in Ford Mustang we also compared:


After the car was assembled, nothing changed externally in the interior:

Installing a Processor and Amplifier in a Ford Mustang
In the Ford Mustang, we decided to use the space behind the passenger seat and the trunk partition to mount the amplifier, processor and subwoofer. Previous experience with a similar car showed that this is the ideal place to place all external devices.
This is what the trunk looked like before work began, after disassembly:

We treated the trunk with vibration and noise insulation, and made a structure consisting of a 19-liter case for the Hertz MP 250 D2.3 subwoofer and a platform for the amplifier and processor:



And as a result, we get a completely hidden audio system, no external modifications, but there is a full-fledged subwoofer on board, which is critically important for high-class sound.

And if you look at the trunk from the outside, then when we close our design with a false panel, it turns out that the volume of the trunk is preserved. View with an installed subwoofer without a decorative panel:

Subwoofer for Ford Mustang
It is better to choose a powerful subwoofer for a convertible, one that can reach your ears and make your body vibrate even with the top open) At the same time, the subwoofer should be compact and the case for it can be of minimal volume. Hertz from the Mille Pro series copes with this perfectly.
The subwoofer enclosure was handcrafted from MDF



Of course, the trunk was well prepared, and noise and vibration insulation was done in two layers using Acoustics materials.

As always, the most important stage of creating a high-quality audio system – processor setup, remains behind the scenes. I will only say that this process takes quite a bit of time, everything depends on thorough setup! Especially when you need to set up a three-band front, and as a result 9 channels (that’s how many came out in the Ford Mustang).
What’s interesting is that in this project we used the processor’s remote control.

So, if you have a Ford Mustang convertible, but it does not have decent music, come to us – we will do everything in the best possible way!
