Stereo-Less Audio - InstallationCruisin' Tunes ...Without A Tuner? From the March, 2010 issue of Rod & Custom By Rob Fortier

The world of car audio equipment sure has come quite a long way since the days of the fold-down 45-rpm record players. These days, thanks to the futuristic advancements of all things iPod (or any number of handheld MP3 players), you can listen to your favorite music in your hot rod or custom without the use of a traditional head unit (stereo). That's right-no bulky radio that you'd normally have to cram in your glovebox or hide beneath the seat facing backward. This is actually my very first... This is actually my very first CD player-sentimental, yes; suitable for my '39 Chevy's audio system, no. In today's world, most things start with an "i", and last I checked, this head unit isn't one of 'em. But while new developments in mobile electronics continue at a pace almost as quick as the speed of sound, it seems one facet of the automotive industry has struggled to keep tempo-ours! Sadly, car audio is usually last on the list when it comes to a new project build, or as part of a hot rod or custom at all for that matter. With the exception of the serious audiophiles among us, sound systems often end up becoming an afterthought-typically, a cheap head unit put wherever requires the least amount of effort, and an even cheaper pair of speakers. For all it's worth (literally), if this sounds like your MO, you're better off foregoing the stereo system altogether. But while the venerable iPod... But while the venerable iPod may think it's ruling supreme, there still needs to be a means in which to convert its puniness into big car audio sound. Enter the V8Audio VC1 four-channel controller. Not only does it bump the frequency like a head unit and interface would, it reduces the necessary space normally required for mounting said head unit. Aside from the budget aspect, what a lot of us can't afford when it comes to a sound system is "space". With a smaller hot rod, there's simply not enough room for all the equipment-at least not if you want a decent setup that is capable of making the quality of noise necessary to compete with your engine's audible output. (That's the thing, most of the cars we drive are not really built to separate driver from exterior noise quite like new automobiles are-so in order to actually hear music, it has to come from a rather powerful source, otherwise, it'll be all distorted.) Still, no matter how well you insulate and sound-deaden your car, you've got a battle with locating stereo equipment. And speaking of reduced size,... And speaking of reduced size, Apple has stepped "down" its arsenal recently with the introduction of its latest Nano-almost to the point where it can't get much smaller! Yet believe it or not, this little guy sports a built-in video camera and, yes, an FM radio transmitter. Santa was indeed generous this year, that's for sure! Well, as the iPod has matured, so too has the ability to incorporate it with the automobile-including hot rods and customs. Nowadays, things have become so advanced and simplified, that you don't even need a traditional stereo (head unit) in order to enjoy quality music while driving, thanks to a little pre-amp device from V8Audio-their VC1 four-channel audio controller-combined with an iPod interface such as SoundGate's Core integration device and a compact yet powerful multi-channel amplifier like Kicker's ZX550.3 420-watt unit (coupled with their QS60.2 component speaker system). With the exception of the speakers (and maybe the VC1 controller, depending on your accessibility preferences), you can literally put all of the above beneath your seat, making it a perfect setup for even the smallest hot rod with cramped quarters. For a larger interior compartment, however, you'll have the room to branch out if need be-but the bottom line is, you'll get top-of-the-line audio performance with a minimal amount of componentry to install ... namely the head unit! In a nutshell, the SoundGate kit allows you to operate your iPod through most any factory/aftermarket stereo and charge it at the same time; the V8Audio VC1 eliminates the need for aforementioned stereo, plus boosts the frequency of your iPod, thus providing the quality stereo sound; and the Kicker amplifier does just what its name implies: amplifies. All together, they provide the perfect means to equipping any old car with modern tunes, plain ... and simple!  As SoundGate puts it, "Simple-Fi"...  As SoundGate puts it, "Simple-Fi" with its Core interface device for iPods and you not only connect to most any factory or aftermarket stereo, but keep your iPod charged too. Take it a step further, though, and eliminate the stereo aspect altogether with the V8Audio controller. Run through a decent-powered amplifier and quality drivers (speakers), your car's audio will be amazingly crisp, clear, and LOUD!  The SoundGate device can be...  The SoundGate device can be powered by wiring directly to your car's fuse panel, as I'm about to do, or via a charging port, also known as a cigarette lighter in old car terminology. As for connecting to a car stereo, that can be achieved with either the single headphone jack plug or via RCA cable.  While foregoing the traditional...  While foregoing the traditional stereo, in order to adequately increase music output, a suitable power amplifier such as Kicker's ZX550.3 multi-channel amp (or equivalent) is required.  To not only complement the...  To not only complement the ZX-series amp, but to handle its output (i.e. produce undistorted sound at the higher levels the music will be played at), Kicker's QS60.2 component speaker system will ultimately be used. The QS-series are capable of producing an amazing full range of crisp, clear sound.  To facilitate all the components...  To facilitate all the components together, for about $20, I obtained a basic "amp install kit", which entails RCA cables, heavy-gauge power (with inline fuse) and ground, speaker wire, and brass connectors.  The VC1 will require input...  The VC1 will require input from the iPod via the SoundGate Core (red/white RCAs), output to the amp (two sets of yellow RCAs), as well as power input/output (pre-wired). Keep in mind where you'll be mounting both the VC1 and your power amp, as that will determine the length of RCA cables you'll need.  Since I've already centrally...  Since I've already centrally located the fuse panel and battery beneath the bench seat in my '39, I'll keep most of the audio components in close range to make installation and wiring easier. Both the VC1 and Core devices need constant and switched power, which fortunately the American Autowire panel provided.  This is just to give you a...  This is just to give you a better visual (a physical schematic, if you will) of the system's wiring layout. Ultimately, the VC1 will be mounted within driver's reach, but the rest of the components will remain in the seat pan where they are now.  For the amplifier's power...  For the amplifier's power supply and ground (wired directly to the battery), it's imperative to use the proper gauge wiring as well as provide an inline 60-amp fuse (mounted within 18 inches of the battery). The blue wire between the two is the remote turn-on from the VC1 unit.  Kicker's ZX550.3 supports...  Kicker's ZX550.3 supports one pair of speakers, which is more than sufficient for a hot rod or smaller cabined vehicle; for applications with larger interiors, you'll want to consider a four-channel amp with sufficient outputs, such as the ZX700.5.  No head unit means you'll...  No head unit means you'll have to control your iPod the old-fashioned way-through your iPod. But with the addition of the SoundGate Core and the V8Audio VC1, you can do so while keeping your iPod charged and increasing its output.  I've yet to decide just "where"...  I've yet to decide just "where" to mount the VC1 controller-either vertically on the seat pan or horizontally beneath the dash. While the latter is a bit more visible, it eliminates having to adjust the controls "blindly", thus presenting a deterrence most law enforcement are likely to pull you over for, if you know what I mean.  Finally, the Kicker ZX-series...  Finally, the Kicker ZX-series amp is also equipped to support a subwoofer, which the '39 will be getting. One of its additional features is a remote bass controller, which will come in handy to simmer the "boom" when necessary!
