Aluminum shell and Aluminum knob to sure high quality, comes a 19V power supply that can fit with the amplifier well. 18-month warranty, you can return the item if you have any problems;

Output Coil with Magnetic Shield prevents magnetic flux from radiating from the subwoofer's coil, resulting in reduced noise and enhanced sound quality.

Detachable sliding terminal cover offers a sleek design and easier installation.

All terminals and connections are on one side for easier installation and a cleaner look.

Speaker Level Input Harness is included to connect to speaker wires from factory installed receivers.

The amplifier design is Class D, which uses digital switching power supplies. The result is the amplifier runs more efficiently, generating less heat than Class AB amps. The Class D design also allows the amplifier to be built on a small chassis, and installed where space is limited.

Power - 3400 Watts Max x 1 @1-Ohm, 1700 Watts Max x 1 @2-Ohms, 850 Watts Max x 1 @4-Ohms

Class D - Power loss is significantly reduced making the amplifier highly efficient. Excess energy is stored until it’s needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry

1 Ohm Stable - Able to continuously power loads of 1 Ohm without encountering difficulties such as overheating. Typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made to

Mosfet Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage and current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry

Strapping Capable - You are able to strap two R3400D amplifiers and double the power that is being sent to your subwoofer(s). You now have the ability to connect more subwoofers to take advantage of the extra power

Variable Subsonic Filter - To prevent your subwoofer(s) from bottoming out, the variable subsonic filter filters out frequencies below the subwoofer(s) specified low frequency limits and allows the driver to reach a maximum safe excursion

Variable Low-Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies. You can set exact sound specifications for the bass frequency reproduction

Specs - Dimensions: 13.5” x 10.44” x 2.25”, Weight: 7.63 lbs.

Warranty - BOSS Audio Systems provides a powerful 6 year Platinum Online Dealer Warranty so long as the purchase is made through Amazon.Com. We strongly encourage professional installation of this product to ensure proper and safe functionality
