Land Rover - Car Audio Upgrades


Land Rover Defender - Audio Joy

Designed as a step up from a tractor, this off roader has become the height of chic! However, a rough and ready finish and ridiculously small standard speaker mounting positions offer a huge challenge to the music love.

Despite being the size of some people's garage, there is precious little spare room inside to house a big audio build unless some compromise is made. For the working vehicle however, help is at hand. Provided the vehicle is treated with liberal amounts of Skinz sound deadening, an environment quiet enough to accept good audio, can easily be established. We would thoroughly recommend you have your FOUR MASTER go the extra mile with sound deadening and treat all panels with a Skinz Bulk Pack as the vehicle is pretty noisy as standard.

Once done, why not go for the Rainbow Dream Line DL-C4.2. This extraordinary pair of 4 inchers form German manufacturer, Rainbow, brings to bear a rich history and deep knowledge of vehicle interiors and provide a surprisingly rich sound with trade mark clarity at the top end. This relatively quick and easy fix will have most intrigued as to just how good the vehicle could send if space was given over to a more significant build. However, even without this the Rainbow Dream Line DL-C4.2's will radically improve the small sound that comes as standard to this vehicle.

Approx. Equipment Cost - £259.98

Excludes accessories and labour (charged at £65 + vat per hour).

Land Rover Discovery - Audio Heaven

More refined and blessed with comfortable seats and better windows than the workhorse Defender, the Discovery still requires some work to make it sound as beautiful as its ownership can be!

In this example of the ultimate Hipster vehicle, great lengths have been gone to, to ensure that occupants are driven to Audio Heaven every time they jump in. Despite the outside dimensions, the inside is not blessed with acres of spare space however, the vehicle does have scope for a 3-way component set up front and a replacement 2-way component set in the rear. Here, once as many panels as can be reached have been treated for sound using Skinz Sound Deadening, the fabulous mini multi-channel Audison Prima amplifier is secreted away. The Audison Prima 8.9 bit amplifier is a minor miracle of audio engineering delivering power to up to eight different channels but also containing sophisticated equalisation and time alignment possibilities on each of those channels.

The seemingly small amount of power from the amplifier is output to each individual speaker at the front. This enables the installer to carefully balance the sound and the resulting performance is far from quiet! The speakers of choice for the front are the very excellent Hertz Mille Pro which are becoming the mid-priced weapon of choice for many FOUR MASTERS as they offer great mounting flexibility and better than expected performance at this price point. These efficient speakers will deliver high output from low power and share many technologies with the bigger brother, Mille Legends. The advantage of running a 3-way set up is that heavy cone excursion from bass notes can be kept away from the speakers responsible for delivering mid and high frequencies avoiding any chance of overwhelming mid bass and treble or introducing distortion. In fact this combination is so clean that there is no listener fatigue experienced even on the longest journeys. The rear speakers are also from the Mille Pro range and run passively via an exceptional passive crossover network. When no rear-seated passengers are in the vehicle these can be turned down to provide subtle ambient fill, or turned off if you prefer a pure stereo experience.

Approx. Equipment Cost - £1479.93

Excludes accessories and labour (charged at £65 + vat per hour).

Land Rover Discovery - Audio Expert

Are you serious about music? I mean, really serious? If you own a Land Rover Discovery and love music you just have to do this to your vehicle! An audiophile's dream for your beloved machine.

In car audio you can literally spend as little or as much as you want to get your music sounding as good on the road as it does in your home or at your favourite club. In this particular case, the equipment choices scream quality but be prepared to have your vehicle modified somewhat to accommodate these incredible products.

By no means the most expensive automotive amplifier available, the Audison Voce AV 5.1K, 5-channel amplifier combines the finest amplifier topologies with robust build quality and first class performance. The amplifier features a class A pair of channels a par of class AB and a class D stage capable of being used for welding! Class A is the ultimate semiconductor configuration with an "ever ready" characteristic. However, due to its relatively high power draw, in this case, it is used sparingly to drive a pair of Rainbow Profi PL-T28 tweeters. These tweeters are larger than normal as they feature a large back chamber that reduces the resonant frequency to below 900Hz. This enables signals to be crossed over at relatively low frequencies to ensure that they are treated with absolute care and precision with no risk of contamination from heavy excursion bass frequencies that may be present in the woofers. With a heady selection of damping materials, these tweeters sing without colouration or peaks.

Mid and low frequencies are handled by the Rainbow Profi PL-W6C 6" drivers which have a pioneering crystal cone shape which offers extra wide dispersion - Essential to combat the poor speaker placement in a vehicle. With most original fit speakers producing a narrow beam of sound usually at the driver's knees or even ankles. These speakers sound just as good to the side as they do in front which effectively removes this issue.

Finally, an Audison Voce 12" subwoofer in a custom enclosure is secured in the luggage space. This is run from the 1000 Watt Class D channel of the Voce 5.1K amplifier. All of the signals are passed through the highly capable Audison bit One processor. This sophisticated product allows the installer to finely equalise and time align the outputs to all channels so that an ideal sweet spot can be established right in front of the driver. The bit One will however store up to four separate settings which allow for a more general setting when travelling with passengers or for specific genre preferences.

Expect pinpoint accuracy, perfect distortion-free clarity and excitement beyond all expectations with this system. FI you love your music, this system is well worth the investment.
