Product Description
This is the ultimate Porsche sound upgrade for those who want reference-grade audio across both front and rear seats. Using Audison’s finest Voce II front stage combined with rear coaxials and the flagship Forza DSP amplifier, this system transforms your Porsche cabin into a world-class hi-fi environment.
The front 3-way system features Voce II AV 1.1 tweeters for silky highs, Voce II AV 3.0 mids for rich midrange, and Prima AP 8 woofers for deep, controlled bass. Rear passengers benefit from APBMW X4M coaxials, ensuring tonal consistency across the whole cabin.
Powering the system is the Audison Forza AF M8.14 bit DSP amplifier, a high-power 8-channel amp with 4 additional DSP pre-outs for expansion. With 120W per channel and industry-leading DSP processing, it provides the headroom and tuning flexibility required for audiophile-level precision. Every speaker is calibrated for time alignment, EQ, and crossover settings — creating an audio stage where instruments sound lifelike and vocals sit dead-centre.
The installation is finished with enhanced 3-layer Skinz soundproofing, turning the Porsche doors into acoustically tuned enclosures. This reduces resonance, blocks road noise, and allows the upgraded drivers and DSP to perform at their best.
