QS Series amplifiers are all about efficient design capable of full-range frequency response at a great price! The QS3000 features a regulated power supply that is able to constantly deliver power and provides an unsurpassed efficiency rate of 80–90% in a small aluminum heatsink.

The QS series is our most recent line of full bridge high wattage amplifiers. You can count on these amplifiers to deliver incredible value for your money. QS3000 at 1 Ohm Stable, also available at 2 Ohm. Its wide frequency response allows you to use it in many different applications, such as subwoofers, midbass, midrange, full range speakers, phenolic drivers, titanium drivers, and super tweeters, among others. This versatile amplifier is the perfect solution for daily car audio systems.

Built-in HIGH and LOW pass filters allow the user to set the right frequency range for his equipment, from deep bass all the way to high frequencies. This proprietary heat dissipation design will ensure a high air flow cooling fans controls its temperature to run cool on the most demanding playlists.

The LED indicator is a simple built-in tool that allows you to easily monitor the status of your amplifier while it is in use. Its clipping indicator flashes at the limit of its maximum power output without any distortion, providing excellent sound performance while giving you the best value! All are protected by four-stage intelligent protection circuitry.

Before Installing:

Before connecting your amplifier review all recommendations thoroughly, Any connection to the amplifier input or output must be performed only when the amplifier is OFF.

• 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.
