🔧 Crunch GTX1800.2D – Power, Flexibility and Control

The Crunch GTX1800.2D is the most powerful two-channel amplifier in the GRAVITY series.
It operates using Class D technology and offers configuration flexibility, making it ideal for powering both a pair of speakers and a subwoofer .

---

🔈 Application 1 – Powering a pair of speakers

• Built-in high-pass crossovers (HPF) eliminate the lowest frequencies that could burden the speakers and cause distortion.

• The sound is cleaner, dynamic and more natural .

• Boosting the treble improves sound clarity in cars where the speakers are mounted low or at the rear.

---

🎶 Application 2 – Powering the subwoofer

• The amplifier offers a bridge mode – allowing you to combine the power of two channels to drive one subwoofer with a minimum impedance of 4 Ω .

• The low-pass crossover (LPF) cuts off high frequencies, providing clean, powerful bass.

• Possibility to increase low tones (bass boost) for an even fuller sound.

• For subwoofers with an impedance of 1–2 Ω, it is recommended to use a monoblock .
