1000w 4 channel car amplifier

CA-480-B

Car Amplifier Class AB

Features:

Basic power amplifier （entry-level）

Full frequency

High cost performance

Class AB

The circuit board is single-sided

Mainly based on traffic

Power of 4 channels is less than 100W RMS

Function Operation Instructions:

Power on or off

Connected power supply,the 12V is connected to the level positive electrode,and the negative pole of the ground wire and the level are connected together.

1.MOSFET Power Supply
Metal Oxide Semiconductor Field-Effect Transistors quickly switch from full to non-conduction for high efficiency output.
2.Class A/B
Our Class-A/B amplifiers feature specific linear circuitry that increases sound quality and power output while reducing distortion and improving efficiency.
3.Bridgeable
Combine the channels of a 2 or 4 channel amplifier to provide a dramatic increase in power output.
4.2 Ohm Stable
2-Ohm stable comfortably powers speakers or subwoofers when in use at 2-Ohms, resulting in more power and volume.
5.Variable Low Pass Filter
Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer.
6.Variable High Pass Filter
Variable high-pass filter gives you the ability to filter the frequencies that pass through to the full range speakers.
7.Variable Bass Boost
Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.
8.High and Low Level Inputs
High-level inputs accept speaker output signals and low-level inputs accept pre-amp output signals to allow for the addition of amps and processors to standard factory or aftermarket source units.

SUOER CA series 4 channels
Put your music into high gear and take off with the Stage Class A/B 4 Channel Full Range Amplifier.
With 1500 Watts Max Power and MOSFET power supply, this Amplifier is ideal for your entire audio system. It can power up your speakers, subwoofers or a combination of both. Customize the sound with Variable Low Pass Crossover, Variable High Pass Crossover and Variable Bass Boost. Bridge the channels for more power and flexibility. Both low and high level inputs are available so that if your receiver does not have one, it will have the other.
Short Protection
Automatic shut-off protects the amplifier if it gets too hot or if speakers fail causing a short.
Switchable Input Sensitivity
Switchable input sensitivity provides adjustable control over the input signal from the head unit to achieve customized balance between power and sound quality.
12v 2/4 channel power amplifier car audio

●Power - 1500 Watts Max x 4 @4-Ohms,900 Watts Max x 4 @2-Ohms, 1120 Watts Max x 2 Bridged @4 Ohms;
●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;
●Full Range - With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers;
●Mosfet Power Supply - A MOSFET is basically 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;
●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: 318mmx 230mm x 50mm, Weight: 2.27Kg.
