Overview

PRV Audio QS7000 1 Ohm QS Series 1-Channel Full-Range Amplifier 7000W

The QS Series amplifiers are built specifically for mids and highs, making them ideal for powering high-output stuntwalls, custom door panels, or any large-scale system demanding louder and more articulate sound reproduction for PRO Audio loudspeakers.

QS Series amplifiers focus on efficient engineering, delivering full-range frequency response performance at an affordable price.

The QS7000 is equipped with a regulated power supply that consistently delivers stable power output. Its design achieves an exceptional efficiency rate of 78%, minimizing energy loss. All of this performance is housed within a compact aluminum heatsink for effective thermal management.

  • 7000 watts true RMS at full range output using Digital Class D Brazilian Technology
  • 1-channel car amplifier stable at 1 ohm for flexible multi-speaker setups
  • High-efficiency full-range design to maximize output from your vehicle's electrical system
  • Compact chassis with 17.25″ x 10.25″ x 3″ dimensions for easy installation in tight spaces
  • 4-way protection circuitry includes high/low voltage, short, and current protection with top-mounted LED indicators

High Power Amplifier designed for custom car audio systems, the QS series delivers premium Full Range HD Sound for clearer, louder output with PRO Audio loudspeakers. Ideal for 8x 10” loudspeakers, the QS7000 is stable at 1 Ohm, with a 2 Ohm version also available for added flexibility.

Its broad frequency response makes it suitable for a wide range of applications—including subwoofers, midbass, midrange, full-range speakers, phenolic and titanium drivers, and super tweeters. This all-purpose amplifier is an ideal fit for daily car audio systems that demand both power and versatility.

Built-in high and low pass filters give users the ability to fine-tune the frequency range for their setup—from deep bass to crisp highs.

Premium Tiffany-style RCA inputs provide a secure, tight connection that minimizes issues from vibrations.

This proprietary heat dissipation design ensures high airflow, with cooling fans regulating temperature to keep the system running cool even during the most demanding playlists.

The LED indicator is a convenient built-in feature that lets you monitor your amplifier’s operating status in real time.

The clipping indicator flashes when the amplifier reaches its maximum clean power output, helping you maintain distortion-free performance. All functions are safeguarded by a four-stage intelligent protection circuit for reliable, long-term use.

Before Installing

You must follow the instructions for the product’s installation to guarantee optimal performance. If you have any questions, get in touch with us. Before using the amplifier, always follow these guidelines:

  • The gauge of the power supply wiring is extremely important to reach the desired amplifier output and for the amplifier’s safety. Not using the recommended wire gauge will result in power loss and overheating of cables. It is important that the power supply cables are the shortest possible length. Always use 100% Copper cables and good quality connectors. This guarantees the sound’s quality and fidelity; To avoid damaging the cables, make sure that they do not touch sharp metal edges. Important: Use a fuse 12 inches away from the battery as a safety precaution
  • Keep all cables as far away as possible from the ignition cables, electronic injection modules and starter switch since they may cause noise interference;
  • In order to avoid interference, the signal cables ( RCA) must be kept away from the original wiring of the vehicle and from any other power supply cable.
  • Amplifier must be installed in a solid and ventilated area. Do not mount amplifier to the back of a subwoofer box; excess vibration may cause damage to the amplifier.

    The power rating data is based on equipment from the PRV Audio Group laboratory.
