Power Acoustik CB4‑1200 – Caliber Series 1,200W 4‑Channel Class A/B Car Audio Amplifier
The Power Acoustik CB4‑1200 from the Caliber Series is a full-range 4-channel Class A/B amplifier designed for car audio setups that demand clarity, flexibility, and stable power distribution. With 1,200 watts of peak output and a clean signal across multiple channels, it’s built to drive mids, highs, or bridged subwoofer configurations with efficiency and control.
As part of Power Acoustik’s long-standing Caliber lineup, the CB4‑1200 reflects a focus on build durability and audio consistency. Whether you're running component speakers, coaxials, or pairing it with subwoofers in bridged mode, this amplifier maintains output under load with a smart thermal design and versatile tuning options.
Configurable Output for Multi-Speaker Systems
The CB4‑1200 is ideal for front and rear speaker setups, 2-channel bridged installs, or small subwoofer integration. It provides a clean signal at both 4 and 2 ohms, with true stereo and bridged channel options for power flexibility.
Power Ratings:
- 120W x 4 @ 4 Ohm
- 150W x 4 @ 2 Ohm
- 300W x 2 @ 4 Ohm (bridged)
- 1,200W Peak Output
This range gives you room to drive both door speakers and woofers without taxing your system or introducing distortion — ideal for daily drivers, sound quality builds, or system expansion platforms.
Designed for Reliability in Real-World Installs
The amplifier’s Class A/B topology delivers rich analog warmth with high output stability, supported by a PWM MOSFET power supply and military-grade PCB design that resists failure under temperature or vibration.
- 2-ohm stereo stable / 4-ohm bridged
- Direct short, thermal, and overload protection
- Aluminum heat sink chassis for passive cooling
- Soft-start turn-on circuitry reduces current spikes during ignition
Installation is simplified with support for both high-level speaker input and low-level RCA inputs (200 mV–6 V), along with a pre-amp output for daisy-chaining to additional amps.
Audio Control & System Tuning
The CB4‑1200 includes essential crossover and gain adjustments for tailoring your system to your speakers and vehicle acoustics:
- Variable high-pass and low-pass crossovers (12 dB/octave)
- 12 dB bass boost control
- Wired remote gain knob included
- LED status indicators for power and protection diagnostics
These features allow precise control over frequency shaping, level balancing, and bass response — especially useful when running door mids with a small subwoofer or coaxial rears.
Applications & Use Cases
The CB4‑1200 works across a wide variety of setups:
- 4-speaker stereo systems (doors, deck, dash)
- Bridged 2-channel setups for high-power component pairs
- Mids/highs with bass reinforcement via amp pairing
- Entry-level SPL systems with efficient speaker loads
- OEM or aftermarket head units with high or low-level signal paths
It’s particularly suited for users who want the analog warmth and tonal detail of a traditional Class A/B amplifier, with modern protection and installation flexibility.
