CAR SPECIFIC Upgrade for the OEM sound system
Most OEM speaker systems cannot completely satisfy the expectations of sophisticated customers. Especially the basic equipment leaves a lot of space for improvements of dynamics and sound quality.
Installing car specific aftermarket speakers is a simple way to enhance the audio system.
GROUND ZERO´s line of CAR SPECIFIC solutions consists of various components designed for upgrading the OEM audio systems of modern cars easily.
Car Specific Amplifier
The results of three years of development, uncountable listening sessions, comparisons, tuning and testing led to the GZ ULTRA A-2, the most advanced analogue amplifier on the market uniting perfectly selected components reduced to the minimum of distractingly influencing aspects creating a masterpiece of an amplifier, matching our very own intention and everybody´s uncompromised expectations, worth to be called ultra-high-end.
Not a huge surprise but a great honour, the performance of the GZ ULTRA A-2 charmed the members of the EISA, a group of international car audio trade journalists, right from the very first listening sessions that much that there was any doubt about the decision to award this amplifier as
“BEST PRODUCT – IN-CAR HIGH-END COMPONENT”
The designation of the REFERENCE 2PURE and 4PURE amplifiers reveal the essential idea behind: Pure Sound Quality! By omitting strictly any kind of signal affecting filter, the result is a completely new and impressing high-end audio performance never heard before.
Only the best components ever have been considered good enough to find their way to the REFERENCE amplifier line-up.
Cooled by a high-quality copper-anodized aluminum heat sink, each model has been equipped with a slightly toned acrylic bottom allowing a glance on the selected components accurately arranged on the discreetly white illuminated and copper-plated double-layer pc board.

Based on a particularly designed aluminum cast basket the engineers have realized a powerful 6.5” midwoofer with a strong ferrite motor and oversized CCA voice coil. In combination with a vented silk dome tweeter equipped with a coupled chamber and a passive crossover, the new HYDROGEN series 2-way system is born for customers looking for an extraordinary performance. The loudspeakers are available separately for active setups, as well.
Each RADIOACTIVE line speaker has been developed following the market request for dynamical and high-efficient audio reproduction. Particular materials used for the mid woofers and tweeters enhance the performance especially when listening to compressed music files. Apart from that, the NEO offer a significantly reduced installation depth by using high-effective neodymium magnets.
The TITANIUM line contains the lately introduced new range of coaxial and component speaker systems with yellow color 3D-HQPP cone.
The IRIDIUM line includes a wide range of coaxial and component speaker systems in the favorable price segment including some models with a particularly low installation depth.
In addition to separately available tweeters and midrange speakers as well as subwoofers, the COMPETITION series also includes some high-tech loudspeaker systems for special applications at the highest sound and performance level.
Car Specific Speaker Components
ULTRA speakers are designed for the most demanding music lover.
Carefully built by hand with the best materials and selected in pairs, they are delivered in fine wooden boxes.
The mid-bass driver ULTRA K-165 uses a high-tech fabric cone “Made in Germany” in conjunction with linear suspension and a narrow-tolerance copper voice coil with a linearized NEO motor. Built in a filigree aluminum basket for optimal air flow, these are the ingredients for outstanding neutrality and sound quality.
The tweeter ULTRA T-30 with its 30mm coated silk dome is characterized by a particularly low resonance frequency and extreme neutrality. The linearized NEO magnet system with the complex rear ventilation of the cone in the solid aluminum housing enables the wonderfully spatial and precise audio reproduction with an extremely wide frequency range.
REFERENCE speakers are designed for demanding high-end music lovers. Accurately hand built in Europe, selected in corresponding pairs and delivered in classy wooden boxes. Midbass and midrange speakers are made from hand-coated, pressed paper cones and hand-spooled copper voice coils, inserted into manually machined aluminum parts of the basket, forming the basis for outstanding high-end sound quality. The tweeter features a particularly low resonance frequency. The usable wide frequency range of the hand-coated silk dome thus enables astonishingly spatial and precise audio reproduction.
In order to compile an individual sound quality setup at highest level, the speakers of the PLUTONIUM line are available in pairs as components separately.
