Class A/B Topology - Class ‘A’ amplifiers have enormous amount of current flowing through its output transistors with no audio signal. Class ‘B’ amplifiers have no current flowing through its outputs with no audio signal

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

Low & High Level Inputs - A low level (RCA) input is measured in voltages. A high level (+/- wire) input is measured in wattages. Both essentially carry signal from your receiver to your amplifier to your speakers

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

Switchable Bass Boost - Bass Boost allows you to adjust the low bass within the boost range to just the way you like it

Variable Input Gain Control - The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier

Specs - Dimensions: 9.13” x 10.44” x 2.25”, Weight: 4.43 lbs., Speaker Impedance: 2 to 8 Ohm, THD @ RMS Output: 0.01%, S/N Ratio: 102 dB, Frequency Response: 9 Hz to 50 kHz, Fuse Quantity: 1 30 Amp ATO Blade

Warranty - BOSS Audio Systems provides a 6 Year Platinum Online Dealer Warranty for purchases through Amazon.Com. We strongly encourage professional installation of this product to ensure proper functionality

Power - 3000 Max x 1 @1-Ohm, 1500 Max x 1 @2-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

Strapping Capable - You are able to strap TWO PL3000.1D 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
