6000W RMS 1-Ohm Mono Zero6 Amp + 2 Dual 1-Ohm 3500W 15" Subwoofers B2-Z6-COMBO2

This Listing Includes

• (1) B2 Audio ZERO6 6000W 1-Ohm Monoblock Amplifier


• (2) B2 Audio RAGEXL V2 15" 3500W RMS Dual 1-Ohm Subwoofers

Dominate the bass with the B2-Z6-COMBO2, a competition-ready system built for audiophiles and SPL competitors. At its core is the B2 Audio ZERO6 "Yggdrasil" Monoblock Amplifier, delivering a true 6000W RMS at 1 ohm with precision and reliability. Paired with two B2 Audio RAGEXL V2 15" Subwoofers, each rated at 3500W RMS and peaking at 10,000W, this combo produces ground-shaking lows with exceptional clarity and extreme excursion.

The RAGEXL 15’s dual 1-ohm voice coils and high Xmax design deliver massive, controlled bass. That, alongside the ZERO6 amplifier, ensures optimal performance with triple 0 GA power/ground inputs, 8-toroid half-bridge design, and the ACCU8 crossover system with 41 detented tuning points. We took the guesswork out of tuning with our built-in clip indicator, letting you fine-tune every beat.

For advanced builds, the ZERO6 has a Master/Slave daisy-chain capability. That allows you to strap or link multiple amplifiers for synchronized bass across your system.
