ILLUMINATED HEAT SINK & FRONT PANEL – with its illuminated heat sink and front panel that includes the volume, bass and treble rotary knobs this will be a statement piece like no other

Power - 800 Watts Max x 2 @2-Ohms 400 Watts Max x 2 @4-Ohms 1600 Watts Max x 1 Bridged @4 Ohms

Full Range - With a Full Range amplifier you not only have the option to run your speakers but also your subwoofers

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 and current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry

Variable 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

Variable Bass Boost - With Variable Bass Boost you have the control of exactly how much BASS you want to pump out to your subwoofer(s)

Bridgeable - Dramatically increase the power output to you speakers and subwoofers by connecting two amplifier channels

Specs - Dimensions 14” x 10 3” x 2 3” Weight 9 lbs

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

This super small mono amplifier is surprisingly powerful - able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC.

Since the amp is a class D, its very efficient (over 90% efficient when driving an 8Ω speaker at over half a Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. There's even a volume trim pot so you can adjust the volume on the board down from the default 24dB gain. This board is a welcome upgrade to basic "LM386" amps!

The A+ and A- inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the Audio- pin to ground. The output is "Bridge Tied" - that means the output pins connect directly to the speaker pins, no connection to ground.

Comes with a fully assembled and tested breakout board. We also include header to plug it into a breadboard and a 3.5mm screw-terminal blocks so you can easily attach/detach your speaker. You will be ready to rock in 15 minutes! Speaker is not included, use any 4 ohm or greater impedance speaker.

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

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

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

Specs - Dimensions: 11.9” x 7” x 2.3”, Weight 6.7 lbs.

UNIQUE APPEARANCE-All aluminum front-panel by precise CNC machining, all aluminum cover with sand blasting treatment, innovative circle-type power light.

FEATURES-Overvoltage protection(Over DC14.4V),short-circuit protection, time-delay circuit design to avoid momentary shock damage to speaker boxes.

State of the art design using surface mount components and advanced engineering for proven performance, reduced signal interference, and long operational life.

APPLICATION-Be suitable for ipad,cellphone,MP3 player,CD player, dataplay, computer, decoder,etc.
