Zero 9 (The Osprey)Â
B2 Audio's Zero amplifiers have become icons in the car audio industry for over 15 years. Zero Amplifiers have been the pinnacle of high-quality class D half-brigde amplifiers. Having been riding on a wave of global recognition from world championships and world record-setting predecessors, the Zero comes with an enormous responsibility. These amplifiers are not only exceptional in power ratings and reliability, but they are also masterfully designed with globally sourced high-quality components. The new generation of Zero amplifiers prides itself on unique features and advantages while setting the bar higher.
Logical Quads
The power and ground connection arrangement on the Zero 9Â is fused and arranged logically, which makes it much easier to avoid confusion. In fact, it is a welcomed feature that helps save time and reduce costly mistakes. You don't have to worry about typical confusion that can be found in other amplifier setups. This design includes quad power terminals, also known as "logical quads," which are designed with sense in mind, keeping your wiring job neat and organized.
Half-Bridge in a chain
Can you connect multiple half bridge amplifiers together? Yes, you can connect them in a "chain" mode, and the signal will come from the master amplifier. This is useful if you want to match the gain of the amplifiers or split the signal. This gain feature allows you to fine tune the amplifiers to ensure they have the same voltage and output level.
This amplifier has useful features to make installation easier. With the "remote in and remote out" feature, there's no need to split the switched 12v remote into multiple wires. The dual 4-gauge terminals allow for connection to subwoofers without concern for wire size. The bass remote provides voltage and clip light information from the driver's seat.
Partially Regulated Power
A technology that reduces power loss due to impedance rise in half-bridge designs. This technology is able to deliver more power to higher ohms compared to other unregulated half-bridge technologies. It operates with a dynamic power measurement below 1% THD in order to maximize performance. Additionally, it has slightly minimized regulation above 1% THD to unleash the full potential of the system. The PRP feature is a valuable addition to any half-bridge system, providing unparalleled power and performance.

The Zero 9 is the amplifier that offers features and power, surpassing plenty Half-Bridge designs on the market. It is capable of powering any subwoofer with authority at any warranted impedance. Do keep in mind the amperage and voltage requirements that are needed to fully unleash its potential. The compact footprint might have you fooled. The 800 A fuse rating is there for a reason.
For those who want to monitor their voltage, the bass controller included allows you to keep track of voltage and clipped signals. The Quad fan setup offers different settings for running the fans - all the time, off, or in automatic mode - giving you greater flexibility.
