What Our Customers Say

⭐⭐⭐⭐⭐ I had SoundTech create a custom stereo solution for my car a year ago, and it has been an outstanding investment. The team was highly professional, listened to my needs, and crafted a system that exceeded my expectations. The sound quality is phenomenal - it genuinely feels like you're in a home cinema. The installation has been done so discreetly that passengers often assume it's the stock car stereo! I've received compliments on the superb audio experience, and I couldn't be happier with the results. I highly recommend SoundTech for anyone looking to elevate their in-car audio experience. Their expertise, quality of work, and customer service are unparalleled. Life is too short for a standard car stereo. Go see SoundTech and enjoy how music should sound.

Had Apple CarPlay installed in my 2009 E500. CarPlay works with all the original controls and the installation is totally professional and clean. It looks like it came fitted from Mercedes.

Honza at Soundtech was very knowledgeable and understanding of my wants for my sound system, and gave me easy to understand suggestions for the best outcome for me. Once fitted he analysed and fine tuned my system to suit my car, and then took the time to explain what had been done. I couldn’t be happier with how well it now sounds inside my car!

Had Apple CarPlay installed in my GLA by these guys. Great service, working perfectly- can’t imagine driving without it now. Many thanks legends!
Honza and team did a great job installing a Level 2 package to upgrade my BMW X3 s factory system. Clean install that looks OEM, fantastic front stage quality from new tweeters, mids and subs under the seats. The clarity and volume are significantly improved. The team took the time to understand what music I usually listen to to custom tune for my needs. Thanks again, really enjoying the set-up.

Honza and the team were great. They had a couple of different options to suit my budget and my goofy old van; they booked me in on short notice; and they had everything done within the day. Stoked with the results - chalk and cheese between the old system and the new. Definitely recommend.
Awesome stereo upgrade for my NextGen Ranger

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.

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.

Yes, we have a variety of cars at our workshop for demonstration purposes. We welcome you to visit our workshop and experience the great results we can offer.
