I have a 2017 Toyota Hilux single cab ute that I use for work. I recently made the decision to keep the ute and after previously having high end car audio systems in my other vehicles I was on the lookout for a new system. I often spend 3 hrs a day driving and/or in Sydney traffic :( I was initially drawn to Soundtech because they stock and install reputable German brands such as BRAX, HELIX & MATCH manufactured by Audiotech Fischer. Implementing a processor/processor enabled amplifier opens the door to high end audio! Soundtech and proprietor Honza have extensive experience in installing & tuning high-end processor based car audio systems. Traditionally most car audio installers somehow place single cab utes in the 'too hard' basket for high-end audio systems. This was no problem at all for Honza at Soundtech. After lengthy consultations and modified quotes we mutually arrived at the best sound system for my budget. A new processor enabled amplifier from Helix, new Helix component speakers & a Helix shallow mount 10inch subwoofer (in minimalist enclosure behind the passenger seat) was installed. Comprehensive sound deadening was also carried out. All components were installed in factory locations giving no hint of the new beast... The sound....? AMAZING...!!! The clarity next level! I can highly recommend Helix products. Musicians playing instruments sound like they are performing a concert in the car beside you! Phenomenal sound quality -the subwoofer a powerful companion -the engaging new sound system does not distort at ANY volume :) I am extremely pleased with the outcome -driving has never being such a pleasure. I can highly recommend Honza & the crew at Soundtech. 5/5 stars...!!! :)

The team upgraded the stock and faulty head unit in my 2017 Amarok to a new 10inch screen with all new speakers, tweeters and custom Sub installation that all looks factory. Soundtech were professional, the installation was neat and all done in a day. The sound tuning and the ability to adjust the sub and bass level is a real winner…. Highly recommended.

⭐⭐⭐⭐⭐ I can't say enough good things about SoundTech, Honza, the owner, provided exceptional service from start to finish. I recently had a new sound system fitted to my G20 BMW, and the results are absolutely phenomenal (Steg Subs and components, Match amp with DSP tuning). The attention to detail and expertise demonstrated by the team at SoundTech is truly commendable. Not only did they install the system flawlessly, but they also took the time to understand my preferences and tailor the setup to suit my needs perfectly. Since getting the new sound system installed, my driving experience has been elevated to a whole new level. The clarity, depth, and richness of the sound are simply unmatched. Whether I'm cruising down the highway or stuck in traffic, I find myself enjoying my favorite tunes like never before. I highly recommend SoundTech to anyone interested in enhancing their car audio. Honza and his team are not only knowledgeable and skilled but also genuinely passionate about what they do. If you want to take your car audio experience to the next level, look no further than SoundTech. You won't be disappointed! Thank you, Honza and SoundTech team for the outstanding work. I'll definitely be spreading the word and recommending you to all my friends and family!
I had vibration deadening and soundproofing added to the doors and boot of my new Subaru Outback. There is a noticeable reduction the level of road noise in the cabin and the sound of the factory sound system is very much improved with increased bass and a more crisp sound. Honza is knowledgeable and a pleasure to deal with. I'm very happy with the overall result.

Fantastic service, went down for some advice on installing a radio I had bought. Bloke at the front desk was more than happy to explain to me how to do it myself even though they seemed quite busy. If I needed anything else I would only go back to these guys.

Great service, great communication, highly professional. Told them what I was looking for from an upgraded sound system and they came up with a great solution within my budget. Workmanship was fantastic and everything sounds amazing and perfectly tuned.
Soundtech sorted me out with a sub & box for my 2023 Hilux, posted to Vic. They advised me on a fantastic setup/product for my situation, also at a great price. Worked mint for my setup. Highly recommend 👌

Frequently Asked Questions

Usually it’s about 1-2 days to finish a car stereo installation, but it depends on many factors, starting with the audio package chosen.

No, the warranty does not get affected in any way with our installs. Also upon request, we can restore your vehicle to the factory setup. If you plan to do so, please let us know during our initial consultation.

We work with multiple brands, mostly from Germany and the USA. Specifically, it’s Match, Helix, Brax, Musway, Audio System, ESX, JL Audio, Kicker, Audio Control, STEG and more.

All our installations come with a standard 1-year warranty. However, we do offer care car sound system packages and on-going maintenance services after the 1-year warranty period is complete.

Custom sound tuning allows us to tailor your car audio experience to your unique needs. We tune the entire sound stage and every speaker individually in a similar fashion as it’s done in custom-tuned home sound systems. We utilise the latest technology of digital signal processors, which we supply.

In most cases this is possible and it’s one of many benefits of Plug & Play solutions. Usually, it only requires a new adapter matching your new car. Please contact us for an accurate consultation and quote tailored to your cars.

Basically for everyone who’s passionate about their music. And you do not need to be a true audiophile to recognise the difference. The purpose of sound tuning is to undo the often unsatisfyingly flat performance of car sound systems. A car’s acoustical environment is generally very unfriendly to sound performance and quality. The DSPs allow us to adjust the sound performance and quality to your car’s environment and your unique music preferences.
