Based on above,do you know which country or area is fantastic of big and heavy class AB

let me introduce the procedure for today’s show:

First,we will show you 4 channels class AB big and heavy guys car amplifiers.

Second,we will present you Mono block class D powerful amps.

Third,question and answer part.

Let’s begin with the first part(introducing our 4ch amplifier).For this series,we have RMS 4*80w  4*100w  4*120W  4*150W.
Look at this 4*120w,the net weight is 3.65 kg,and if with foam,package it will reach 4.5 kg/ctn.For common/ordinary similar power 120w,the basic model weight about 2.2 or no more than 3 kg,so it is much heavier than other options.

Then some may wonder why we make is so big and heavy?

1)the first reason is because it is class AB amplifier,as we know the efficiency of class AB AMPLIFIER is about 65-70%, so some of the energy is dissipated in the form of heat.and after continuous playing the surface will get very hot even shutdown to protect the amplifier from over-heated.

Then how to solve this problem?

Obvious we make bigger housing to let the heat dissipation come out and not accumulated.then the inner circuit board will be in safety specs and the surface will be not hot.

Maybe you will wonder,since the shell is so big,then the price is much higher than common ones?yes what you are thinking is 50% right. This model is a little expensive,except the heavy heat-sink,also the layout of inner board is good,and we make top and high quality electronic parts to ensure the excellent quality and performance of products.

If you are a car audio enthusiast,you can compare this model with oridinary one,this sound is very warm and stereo surrounded.

Based on above,do you know which country or area is fantastic of big and heavy class AB.From our previous experience,Russian customer and middle east especially Iran like big and heavy ones.You know in Middle east country t he outdoor temperature is very high(more than 40 degrees),so they need a excellent model,which can meet good performance of sound and heat dissipation requirements.

Except the products itself,let’s check the package. Many clients pay much attention on the gift box,since good products also need good exterior decoration.you can find the box is strong,we especially made drop test for package before put it to mass production.Even after long time and distance of transportation,the box will bear and not broken.

Well,the above is the basic features for it.then we can conclude the following advantages for this series:

1)Big size, good heat dissipation performance.

2)excellent sound quality, it is powerful ;

3)Package good and strong.



These are for our first part,and following let’s start with the second part,powerful RMS 5000W Brazilian amplifier.

So far it is our most powerful amplifier of 5000w@1ohm. It’s high pass frequency response is15hz-80hz and low pass frequency is 20hz-25k hz,we can see it is a full range frequency from 20hz-25khz.

Signal to noise ratio is above 92db.we know the signal-to-noise ratio refers to the ratio of the power of the transmitted signal to the power of the noise involved in the process of propagating the signal.Usually this ratio is expressed in the unit of dB. It is a important parameters which can show the performance
