2012 4 Runner gets an Audison Full D/A sound system and some extreme lighting!

We were happy to be the last stop on this customer’s journey of personalizing his vehicle and we sure like to think he left the best for last!  With a lift, roof rack, upgraded wheels and tires as well as some performance modifications already done, we set out to build him a sound system that would be crystal clear while also having the ability to be nice and loud when he feels like getting on it!  This was, of course, not a problem for us.

We have been having such great results when implementing the Audison Full D/A systems lately and this one is no different.  The “Full D/A” nomenclature indicates that, by system design and the use of specific components, the audio signal is converted from a digital to analog signal only once during the process of reproduction which provides a noise free, crystal clear sound.  The components used in this system were a Pure I-20 ipod kit which feeds an optical output to the Audison Bit One.  This device then takes that signal, as well as the signal from the factory radio (for listening to AM/FM and CDs), processes them and sends them out, still in the digital domain to the Audison Voce 5.1K 5 channel amplifier.  This device then converts the audio to an analog signal and sends it out to a pair of Audison Voce tweeters, a pair of Voce midrange speakers and a Hertz Hi Energy 10″ subwoofer.  The rear speakers, while still hooked up, are faded completely out so as to not ruin the front sound stage.  We treated the doors and the floors with sound deadening material to control unwanted vibrations and noises.

Who needs a killer sound system if you can’t see where you’re going…right?  For the purposes of lighting the way when off-roading or for simply driving in the dark nights of the Northwest (also where this truck calls home), we installed a total of 6 6″ Rigid LED light bars.  We installed 4 of them, 2 spot lights in the middle and 2 flood lights on the outside, on the front of the custom Gobi Stealth roof rack that was previously installed.  The remaining two 6″ flood lights went on the back of the rack for total coverage.  For supplying power to these lights, we had custom switched made that were mounted in the center console.  Their power supply was controlled by a relay so that they could only be turned on when the key was on, so as to prevent the lights from draining the battery.

Turned on.

Here are the two 6″ rear spot lights mounted with custom made brackets.

And all four turned on. Since we wired up 3 independent switches, we are able to have any combination of lights turned on.

Floods turned on.

Spots turned on.

We ran two 6″ spot lights in the middle and two 6″ flood lights on the outside.

The wires were then fed back into the tube, protected from shorting by a rubber grommet, nice and neat. this same process was done in 4 other locations for the other lights.

The wiring for the lights was soldered to the supply lines and then protected with heatshrink.

The wiring for the lights was ran out through the shark fin antenna at the back of the vehicle and then went directly into the tubular roof rack to various points.

When you actually turn the switch on, the image lights up green.

Here are the custom switches we had made for the roof lights, mounted in the center console. When the running lights are on, the label for the lights illuminate amber.

Here you can see the input side of the AV5.1K feature the digital input adapter.

The black paint on the grille material allows the logos underneath to be visible.

This trim piece covers up the AV5.1k and Bit One while allowing them to breathe through the pressed aluminum grille which is painted black and surrounded by a vinyl wrapped trim panel.

A look at the custom enclosure for the Hertz Hi Energy 10″ subwoofer. Notice the 4 Runner raised logo.

A shot of the back end of the vehicle. You can see the custom subwoofer enclosure and the amp rack.

Here is the factory subwoofer and JBL amplifier, this simply won’t do!

A close up of the DRC.

After a little moving around of some switches, we were able to custom mount the DRC in an easy to get to and attractive location.

The new Audison Voce 6.5″ Midrange speakers mounted using a custom adapter plate and some gasket foam to seal it up tight.

We applied a generous amount of sound deadener to the outer skin, inner skin and the door panel of each front door.

New Audison Voce tweeters mounted in place of the factory ones using custom mounting brackets.

What a cool looking 4 Runner!
