Hands-On Installation of the Pioneer SPHERA

Longtime readers will know we’ve been hammering away at improving stereo sound in everyday vehicles. Concert quality audio shouldn’t be restricted to the one-percenters with six-figure luxury MSRPs; it’d be nice if even those of us sticking to a budget could enjoy our favorite tunes the way they were meant to be heard.

Which is why our attention, and the attention of many audiophiles, has been taken by Pioneer and its new SPHERA system. The equipment promises to bring a spatial audio experience via Dolby Atmos in an aftermarket install, something previously only available to buyers of expensive luxury vehicles optioned with complex, top-of-the-line factory systems.

This is why we’ve elected to install a complete Pioneer SPHERA system into a last-generation Nissan Frontier pickup, a truck which represents what the Average Joe or Josephine might have in their driveway. If we can get six-figure sound out of this rig, our results should be replicable in just about any machine.

What is Pioneer SPHERA and Dolby Atmos?

Unlike traditional stereo tracks restricted to separate left and right channels, Dolby Atmos is an object-based audio format. Sound engineers mix music in three-dimensional virtual space, placing instruments, vocals, and ambient effects around and above the listener rather than hard-panning them to fixed speakers.

In factory luxury vehicles, experiencing Atmos often requires massive arrays of a dozen or more speakers. SPHERA changes the game by utilizing Dolby’s specialized 4-channel rendering algorithm.

This processing intelligence allows the head unit to translate native spatial audio files into a complete, enveloping Atmos experience using as few as four speakers in factory locations. Combined with Pioneer’s onboard calibration, it calculates how sound reflects and travels through your specific vehicle interior, rendering a convincing three-dimensional soundstage without needing to cut holes in the headliner for dedicated height speakers

In fact, our own managing editor, who experienced the wonderment of Dolby Atmos in a new Cadillac Escalade iQ at the GM Technical Center, was moved to a physiological response whilst listening to the heightened strains of Rocket Man by Elton John. Such is the powerful ability of Dolby Atmos, a type of sound which is able to get into one’s very core as if being immersed in the very music itself. When it’s all set up properly, of course.

Installation

Which was the task facing our audio install master, Aaron McMullin, the owner of AM Car Stereo & Accessories just over an hour outside of Halifax in the Canadian province Nova Scotia. He’s been professionally installing aftermarket equipment for years, keeping up with the latest trends - like Dolby Atmos - despite modern vehicle dashboard design doing its level best to put a knee in the groin of aftermarket installers like Aaron.

The days of just sliding a single- or double-DIN head unit out of the dash and popping in an equivalently sized upgrade are long gone. Neatly integrated jumbotron touchscreens now dominate the arena, some of which control everything from entertainment to ventilation.

Because of that architecture, the installation started at a workbench PC. Aaron began by flashing an iDatalink Maestro RR interface module. This programmable datalink harness bridges the SPHERA head unit to the Frontier's CAN bus, retaining steering-wheel controls and adding multi-press button mapping—such as allowing a tap to adjust volume and a long press to jump to a custom menu.

After carefully disassembling the Frontier’s center dash and setting aside the factory head unit, our man Aaron complimented some changes he noticed Pioneer had made to its equipment in a bid to ease installation. This proved two things: that Aaron knows his stuff and Pioneer listens to feedback from those doing the hard work, making changes to items the end user is likely to never even see.

Set Up

A critical step in setting up the Pioneer SPHERA system, and the key to unlocking its Dolby Atmos potential, is acoustic calibration. Pioneer accomplishes this through its proprietary Auto Sound Calibration Engine (ACAL), which essentially serves as the secret sauce for bringing true Dolby Atmos into the aftermarket arena. 

While a vehicle interior offers an intimate listening space, it presents major acoustic hurdles: you sit off-axis, positioned much closer to the driver-side speakers than the rest of the cabin. On top of that, an endless list of real-world variables can color the sound, from cabin volume and factory speaker angles to interior upholstery or even fuzzy dice hanging from the rearview mirror. ACAL eliminates the guesswork by measuring these environmental quirks, adjusting frequency response curves, and applying precise time delays so the driver is placed squarely in the sweet spot at the center of the soundstage.

To run ACAL, our installer temporarily placed the included calibration microphone, about the size of a quarter, draped over the driver’s headrest at ear level and connected via the head unit’s auxiliary input. After selecting the vehicle’s cabin size on the display (Aaron chose "Medium" for our crew-cab Frontier; options for compacts and large SUVs are also available), the calibration routine began.

Wisely, Aaron powered the truck with a battery tender rather than running the engine. This kept the electrical system steady while eliminating engine vibrations and exhaust rumble—a smart detail easily overlooked, but one worth requesting from any professional installer. 

With the windows rolled up and doors sealed tight, the SPHERA initiated a roughly five-minute acoustic mapping sweep. The system pulsed bursts of pink noise through each speaker channel, followed by sharp, percussive "knock-knock" test tones. Watching the system bounce sound off the glass and panels to mathematically profile the Frontier’s cabin was fascinating to see in real time.

Performance

Out of the gate, our choice was to first try the system with the truck’s stock speakers, ones installed by line workers in Mississippi as part of its original gear. We elected for this initial test since a key selling point of the Pioneer SPHERA system is that it provides towering sound even with stock speakers - though you know we’ll soon be stuffing this Frontier full of aftermarket Pioneer 6x9s, so watch out for that article in the future.

Connecting devices to the head unit was dead simple, a process we’ll mention in the next section, along with our opinions on the graphics interface. Armed with a playlist of Dolby Atmos music and a solid internet connection - more on that in a minute - Aaron fired up the Frontier and put the SPHERA to work.

It is not disingenuous to suggest that, with the proper source music, Dolby Atmos truly immerses a listener into their tunes. It’s almost as if one is being lowered into a bucket of music, completely immersed by sound emanating from all directions, like being covered by ocean waves or your favorite blanket. It’s clear that Atmos was first developed for movie theaters and the fact that Pioneer has managed to lift that experience wholesale into an aftermarket system which can be installed in just about any vehicle is nothing short of remarkable.

Spatial sound permitted us to feel as if lead singers were standing on the dashboard, backed by vocals coming from somewhere in the backseat and instruments from the left and right. Yet, it didn’t feel artificial or falsely separated or echoey, an experience some cheaper systems have seemed to provide whilst chasing so-called ‘three-dimensional’ playback which just sounds like you’re in a glass fishbowl.

User Experience

Speaking of, the Pioneer SPHERA system will adjust itself to whatever input it is fed, meaning if your cellular service through which you’re playing Atmos-labelled music is poor, the experience will be automatically graded to whatever the system feels is the best given the inputs. In other words, if one is trying to stream Atmos tunes through one bar of LTE, the system will likely not be able to playback that level of quality. Consider this another vote for buying digital music and storing it locally.

All the same, even local terrestrial radio sounded better on FM frequencies. Response times through the head unit’s 10.1-inch floating touchscreen were more than reasonable and its graphics clarity was superb. A bank of defined-use buttons line the left size of the screen, for quick access to a home menu and such, along with some actual physical controls (what a concept!) along its upper edge. Wireless use of Apple CarPlay was seamless.

Some pleasant functional surprises are baked into the SPHERA’s system. Since the device is connected to the truck’s CAN bus, different microcontrollers and devices can actually talk to the head unit, allowing real-time display of everything from road speed and engine temps to door ajar and check engine warnings. The latter can actually bring up whatever codes are being thrown to trigger the light, rendering a handheld scanner unnecessary. Even if a person isn’t into fixing their own vehicles, it still arms them with information when talking to a mechanic. This feature alone helps sell the system in our eyes, especially if one is trying to justify the cost to a skeptical partner.

Music Types

Apple Music has whole playlists of Dolby Atmos tunes and should be a go-to source for anyone with a Pioneer SPHERA system in their vehicle (again, pending your own connection strength). This author likes EDM despite his rapidly advancing age, finding certain tracks from artists like Eric Prydz or Kaskade to sound of even quality, absent the atmosphere of EDC or Ultra, of course. Classic rock and powerful ‘90s tunes also made the initial playlist, not all of which were Atmos, essential genres because your writer is a wretched millennial born in the early 1980s.

If one feels their new Pioneer SPHERA system needs fine tuning, remember the computer coding credo of ‘garbage in, garbage out’. Feeding an Atmos-capable system low-quality inputs and expecting premium sound would be like watching a 144p video on an IMAX screen: it won’t get any better than the original source. That said, even music which was digitally compressed in the extreme (ahem, SiriusXM, ahem) still sounded better than it had any right to, thanks to SPHERA’s advanced processing and ACAL tuning which improved stereo content too.

Optional Gear

As mentioned earlier, all of these frankly phenomenal impressions were made with stock speakers, a testament of Pioneer’s quest to bring this level of sound to the masses. Later, we’ll be adding speakers from the Pioneer, Dynamat-type material, (which, as installer Aaron demonstrated in his own car, basically turns a vehicle into its own subwoofer enclosure), and a sub/amp combo to either supplement or replace the stock gear. Also, insist on your own installer using that Maestro Rr datalink add-on for added button functionality.

Demonstrating the breadth of its ability, the Pioneer SPHERA integrates a top-tier listening experience into one’s daily drive. Dolby Atmos was once promoted by some automakers as an integral part of a factory install, unable to be easily replicated elsewhere. The SPHERA system proves the technology is democratized for all gearheads, making audiophiles out of us all.
