It’s going to be a big few weeks in the BCK workshop with this 79series in for an epic system upgrade.

We’re helping out with a console and steering wheel install, as well as crafting some seriously quality audio using:

✔️ Kenwood DMX9724XDS headunit
✔️ Focal Utopia TBM Tweeters
✔️ Focal Utopia 3.5WM midrange
✔️ Focal Utopia 8WM midbass
✔️ Focal Utopia 10WM subwoofer
✔️ Helix PSIX ultimate 6ch DSP amp
✔️ Helix PONE mono amp

Additionally, there are a bunch of cameras and a heap of sound deadening, plus some serious fabrication!

Stay tuned for some BTS on this one, as well as the final install - and apologies in advance if we miss a call or two!

Customer came to us with an old school custom audio system in their Subaru - unfortunately, unable to get any sound.

After a thorough diagnostic session, we found that the existing processors had failed.

Using more modern technology (the system was built around 15 years ago), we were able to replace these four products with just one. Not only did it resolve the sound issue, but it also made the whole system a lot simpler!

Testament to the original installer, the build is still holding up really well and sounds great 👍🏻

We've just received our first international shipment of premium cables from Europe and we want to know... is this something you've been exploring as well? Options are currently pretty limited in Australia for premium cabling and we're keen to gauge interest from the industry before committing to bringing in more of the range.

At Bay City Kustoms, we're dedicated to providing our customers with premium service, products and outcomes. If you're keen to do the same, but are frustrated with the current lack of premium options in Australia, get in touch to find out more!

We don't shy away from premium factory-fitted systems. No matter how 'premium' these systems are, we can always achieve better quality audio through strategic upgrades.

In this G87 BMW M2, we upgraded the factory Harman Kardon with Audison Prima speakers and an Audison Forza 12ch DSP amplifier.

These custom sails were created using a combination of old school skills and modern technology for a recent RAM build to fit these epic Focal FRAK tweeters.

Whether you’re fine-tuning an audiophile-grade 2-way or 3-way system, the FRAK delivers treble reproduction that is as accurate as it is emotionally captivating.

If you're a car audio nerd and want to 'nerd out' planning your next car audio system, pop in anytime!
