Screenshot

I Dismantle this my 3 years old NBN subwoofer amplifier to cleaning the box inside. Also I take screenshot what inside this gadget as reference to people want to know inside about.

This kind of amplifier produce DEEP BASS and replex it to the wall if you tune in the frequency controller.
It produce LOW pass normal at 30Hz and better combine to your normal sound stereo to highlight the bass sound. I used it as crossover to my car stereo to make it 2.1 sound system.

WATCH Video below shows a complete detail of UNBOXING and DISMANTLE of this gadget.




Pros and Cons
It is good and durable until this year this amplifier have a good performance.
The Speaker is "open" at side causing accidentally kicked or wet things can damaging it.
have a good heat sink alloy for longer hours operate to prevent heating
You need a Good power supply to work it properly the bass output. It need a super capacitor.
I get burned wires when i using gauge #16 power wires. It means It consume High Current to your Battery.

This NBN Subwoofer is powered by 2 transistor type which is NPN and PNP type powered by step up DC to DC module built-in on PCB that the Maximum output of 150W power output..

And many company create a lot production of these.. Sometimes there are companies make a fakes storage capacity to get the attention of buyer.. What is Fake Storage on microSd and Flashdrive? Sample of these is the product is 32GB SD card or more indicate in their product but the true usable storage is only 8GB. If you use it this Fake storage 32gb, Your data save in there is only 8GB and the rest storage was FAKE when it reach recommended space storage.
