Our team built this custom enclosure for a subwoofer supplied by the customer.

In our opinion, solid enclosures will always sound better, which is why we always internally brace our enclosures, as seen here in the build phase.

If you're looking for a custom designed system, be sure to get in touch.

3D printing is becoming an integral part of our business. It allows us to design solutions to problems which while customers might never see, we simply can’t let go.

This is where BCK stands out from some other shops. We go the extra mile to ensure that even though your headunit might cover the gap, you’re not left with a gaping hole behind it.

This Match UP10DSP was recently fitted into a 2018 Prado.

We fabricated aluminium brackets to ensure we could securely mount the amplifier in the location of the factory amp.

With the factory speakers running actively, we gained a massive increase in sound quality.

The amp helped to provide a much wider sound stage and better centre image.

In our opinion, the best 'bang for buck' upgrade for modern vehicles!

Currently working on a big custom audio system in this Hilux and utilising 3D print where we can to ensure the best fit.

We 3D printed this fuse holder mount to utilise the factory bolt, eliminating the need to drill any additional holes.

This one was printed using ASA-GF filament.

More to come on this system!

Super impressed with how this Alpine iLX-F509Ai went into this 2018 Prado!

Our goal is more than producing sound in your vehicle.

We aim to create a sound environment that allows you to experience the music in the way the producer desired it to be heard.

That means choosing tried and trusted products, sound deadening, effective cable management and proper tuning, among many other elements.

It's the difference between hearing... and experiencing.

So if you're an audio enthusiast looking to make your car sound as impressive as your hi-fi system, you know who to call!
