2.1 Amplifier Soundcheck Good for DIY Soundbar👍🏻 

Soon my friend. I'll try to make tower speakers. But this amplifier can not able to use using 12v battery. The required voltage is only 3.7 V to 5V. 😊

@@Segantech Pam 8403 don't use it all youtuber are using this

Actually today is my last review and I can no longer buy another Pam8403 Amplifiers since I finished my last video earlier. I'm planning to switch to TPA amplifiers soon. 😊

Thanks for giving too much attention to a subscriber from now on I am one of your friend in youtube

Thanks my friend, I really appreciate 😊

Thank you for commenting my friend. The audio IC for left / right and subwoofer is isolated to each other. It means the whole subwoofer ic is running only 20 Watts for subwoofer. Based to the caption the Amplifier is still running good even the power supply is only 3.7v because this amplifier is have a required 5V 2A power supply.😊

I really wonder what China is doing in electronics. The performance of this board is no doubt amazing but when we come towards the Audio IC we find CS8575s a 16 pin 2 channel chip and another smaller chip (might be working as subwoofer pre processing) I was unable to read the smaller chip model without magnifying glass right now. The main Audio IC datasheets call it just a total 3.1 watts stereo audio chip.

Yeah absolutely right. Chinese audio devices have higher spec's on the description even it's is a hype only to impress. So I'll recommended only 3 watts for l/R channel and 10 watts for subwoofer. Because this Amplifier is for basic 2.1 setup only but it's still amazing. Now I decided to switch to TPA amplifier soon. 😊

Let me suggest to use Car Head Units instead of TPA series (If we have enough space to fit them). At their minimum power Car Stereos offer 10w × 4 (at 12 volts dc). The difference is our voltage range. When we run tpa at 12 volts they give almost the same output power that we can get from Car Pre. Car players offer built in amplifier, Bluetooth and multiple input, built in tone controller and equalizer, FM radio as well. They are easily available in local market almost in the same price that we spend for these boards. Believe me I have previously assembled some boom boxes by using Car head units and they sound well close to 2.1 speakers.

The most appealing thing in Car head units is RCA output at the back to add extra amplifiers or subwoofer amps.

Maybe on AliExpress or amazon
