Good vibrations

Written by: Eureka! | Published:

More and more, new cars are being sold on the strength of their in-vehicle infotainment systems. Whether this is having the latest navigation system, video players for keeping younger passengers quiet on long drive, USB and Bluetooth connectivity or Wi-Fi connectivity so passengers can access social media, browse the web or make video calls, one particular feature is far and away the most important component: the audio system.

The tuning craze from the 1980s through to the early 2000s saw an explosion of people customising their cars. For the most part this consisted of sporty-looking body kits featuring scoops and spoilers as well as lowered suspensions, low profile tyres with custom rims and possibly an extreme camber.

But it wasn’t just exterior modification, the sound system was a huge part of this fad with the standard speakers and systems replaced with high-end systems and better speakers... lots of them.

Since these less regulated halcyon days the car industry and more importantly, the tax system, has switched focus to produce and promote vehicles with reduced emissions. Lugging around the extra weight of standard audio systems, let alone giant speakers and bass amps, increases emissions.

The challenge

Withthe automotive industry looking for lightweight solutions to everything, this month’s challenge is to come up with a solution. Your in-vehicle infotainment system must be as lightweight as possible while also producing top of the range sound. Your idea might be so outside the box it contains hardly any standard components that currently make up a traditional system.

The idea we have in mind will be revealed in the May issue of Eureka! Until then see what you can come up with. Submit your ideas by leaving a comment below or by emailing the editor:
