Last updated: 8 October 2026.
This is the detailed build sheet for Pete's own R34 GT-R. It isn't being built purely to chase competition points — the brief is impact, dynamics, thrill and genuine enjoyment behind the wheel. That said, the tune going into it will be built to the same standard Pete holds every car to as a Certified International EMMA Head Judge: competition-level accuracy, in service of a system that's fun to drive every day, not just one that scores well on a sheet.
The system is still being built — it isn't finished yet. Pete's aiming to have it complete in time to enter the first EMMA competition in Sydney on 25 October 2026, time and parts permitting.
Full equipment list
HELIX NEXT V EIGHT DSP ULTIMATE — system brain
8-channel Class HD amplifier (8 x 110W RMS @ 4Ω) with a built-in 14-channel, 64-bit DSP. This runs the entire front 3-way stage directly off its own amp channels, with RCA pre-outs feeding the two subwoofer amps below. Shop the HELIX NEXT V EIGHT DSP ULTIMATE.
PS Sound AMT60 ribbon tweeters — sail panels
PS Sound's AMT (Air Motion Transformer) tweeter, built around a 60mm pleated ribbon diaphragm rather than a conventional dome — low distortion well up into the top octave, with a wide, even dispersion pattern that holds the stereo image together off-axis. Mounted in custom sail panel pods for a direct, unobstructed line to the ears.
STEG Master Stroke MSS3 — dash-mounted midrange
A dedicated 4" (110mm) midrange handling the vocal-critical 150Hz–12kHz band on its own, free of the breakup and beaming a wider-range driver fights at those frequencies. 70W RMS handling, 86dB sensitivity. Dash mounting puts it on-axis with the listening position for precise imaging.
Stereo Integrity TM65 mkIV — midbass
A shallow-mount 6.5" midbass (150W RMS, 4Ω, 7mm Xmax) handling the 80–350Hz range beneath the MSS3. The end-game install for these is the kick panels — but with time pressure on this build, they'll most likely go in first at the OEM door location, and move to the kick panels when there's time to do that properly.
Helix or Brax ML10 — front sub, passenger footwell (model TBA)
A near-field 10" sub mounted in the passenger footwell for fast, well-timed low-end that arrives at the listening position with minimal delay relative to the front stage — powered by its own dedicated amp rather than sharing one with the rear sub. Final model (HELIX or BRAX) still to be decided.
JL Audio HD750/1 — front sub amplifier
750W RMS Class D monoblock dedicated to the front footwell sub, with JL's Single Cycle Control technology to keep Class D switching distortion out of the bass. Running this sub off its own amp (instead of bridging a spare DSP channel) keeps its gain and filters independently adjustable from the rear sub.
One Audio BN3 (18") — rear sub, Infinite Baffle
An 18" driver built specifically for Infinite Baffle use — no box at all, just the boot cavity itself as the "enclosure." IB trades outright SPL efficiency for extension and a very linear, uncoloured low end, which suits the impact-and-dynamics brief here better than a ported box's peakier output. 34mm Xmax and a 1,210cm² cone area give it the excursion headroom IB demands.

HELIX P ONE MK2 — rear sub amplifier
A compact Class D mono amp (500W @ 4Ω / 880W @ 2Ω / 1,500W @ 1Ω) with a high damping factor — important for keeping an IB driver, which has no box to help control it, properly damped. Optical SPDIF input keeps it digitally linked to the V EIGHT DSP ULTIMATE's processing. Shop the HELIX P ONE MK2.
Cuore One DSP controller — hands-on control
damn good audio's Cuore One gives hands-on control of the V EIGHT DSP ULTIMATE from the driver's seat — a 1.3" display, gesture shortcuts for volume banks and presets, and live battery-voltage monitoring so you can see how the system is coping under load. See the Cuore One.
Sound deadening and power
- Sound deadening: STP (Biplast/Gold-series constrained-layer damping), supplied by SDS Solutions in Sydney — an EMMA Australia sponsor. Deadening is the acoustic foundation underneath all of the above: a quieter, less resonant panel is what lets the TM65s and the IB rear sub actually deliver a clean, undistorted signal rather than fighting door and boot-panel buzz.
- Power distribution: Stinger power and earth (ground) distribution blocks, feeding the V EIGHT DSP ULTIMATE, the HD750/1 and the P ONE MK2 from properly fused, correctly gauged runs off the main battery feed.
Why this configuration
Every decision here is in service of the brief: impact, dynamics, thrill and genuine enjoyment behind the wheel — with a tune precise enough to hold up to competition-level scrutiny if this one makes it to a judging table.
- A genuine 3-way active front stage. Splitting tweeter, midrange and midbass onto three dedicated DSP amp channels per side — instead of a 2-way with a passive crossover — means each driver only ever plays the band it's actually good at, with the DSP's time alignment and EQ correcting for where sail panels, dash and doors (or kick panels, eventually) actually sit relative to the listening position.
- Two subs, two jobs. The 10" footwell sub is positioned and amped to blend seamlessly with the front stage's timing — fast, near-field, well-integrated bass. The 18" IB rear sub isn't chasing that same job; it's there for the deep, linear extension an IB alignment does better than almost anything else, powered and damped independently so neither sub compromises the other's tuning.
- Headroom everywhere. Separate amps per subwoofer, a DSP amp sized well above what the front stage actually draws, and distribution blocks sized for the full system rather than daisy-chained ring wiring all mean nothing in this system is working near its ceiling at a level you'd actually drive at — which is where real impact either holds up or runs out of breath right when you want it most.
