What an amazing experience, I had a new subwoofer and dashcam installed by Soundtech, so happy with the quality of the workmanship and customer service experience was second to none.

Dealing with SoundTech and Honza from start to finish was a standout experience. Right from the get-go, Honza was all about helping me find the best setup for my new Toyota GR86 2023. He was straightforward, knew his stuff, and made sure I felt comfortable with the plan for the upgrade. Dropping off the car was easy, and I was kept in the loop with updates and photos, which I really appreciated. When I got the car back, I was blown away by the quality of work. It looked like it all could've been installed straight from the factory - clean, meticulous, and just spot-on.Now, the sound - it's hard to put into words. The car sounds amazing with the new setup. Everything from the sound deadening to the way the system was tuned is perfect. It's got this quality to it now that makes every drive a lot more enjoyable. And they did all this without needing to mess with the car's original head unit or fittings. Big thanks to Sound Tech and Honza. The whole process was smooth, and the results speak for themselves. Definitely recommend them if you're looking to upgrade your car's audio without compromising on aesthetics or originality.

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.

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.
