In the beginning only an amplifier board, then consider still have a box installed a little better, it got a transparent box, no material Acrylic helplessness on hand, the box is still relatively soft, but easy hole, all holes holes are opened with scissors, tired of hand pain.

In addition, in line to buy a fan, but unfortunately did not get the ball, that is, ordinary little fan noise is still there, I knew to buy the silence of the good, the fan into 2.1 interfaces, for my power adapter. 24V6A power adapter is bought, the required current amplifier board 5A above.

Buy a DC5.5 * 2.1mm one point two extension lines, so that the fan can be used simultaneously and the amplifier board. Terminal using a copper cylinder, feel quite Tyrant, banana is also the core of copper, soldered the still very easy to use. Also with two switches, each controlled amplifier board and the fan.

Also engage in a subwoofer, 5-inch box, 5-inch speaker with a pure bass sound speaker Wan, send the screws too short, but fortunately I have a more appropriate long screws, connect the subwoofer amplifier after the plate, the bass is still there, the problem may be an impedance of 8 ohms, can always feel better, I knew a good buy four of Europe, but also okay, after all, power is not great.
