Nice board with good quality sound
this audio amplifier board is working perfectly fine, it have hi-fi gain amplification, how ever it produces a little humming sound on high volume, wiring soldering is very poor, DC/AC power input points are not indicated on board, Heat sink is less in weight compared to IC 4440 heat dissipation rate. Potentiometer Knobs and Nuts are not provided which are very important for installations, wire lengths are very short.

Good one
Nov20, it's working good only with 12v 1 amp adaptors or less than 1 amp. Over heating if I use 2 amp or 3 amp dc 12V...mid bass is very good. Buzz sound is there..even if we use 1 amp adaptor.. They sent different product. But same wattage..No labels for port connection, power port not mentioned. No power swtch cable extenstion sent, its not soldered. Don't know when will it stop.. sound is ok.

Powe input wires missing, Nuts and knobs are missing
Product is good, but some essential things are missing, nuts for tighten the volume controls are missing, how am I supposed to fix it to the housing? And the knobs, without the knobs how can I adjust the volume, and the most important, power input wires are not soldered to circuit, they are missing, add these essentials accessories

Not good
overall good stereo sound quality, use a different power supply for Bluetooth module or use a dc to dc isolated converter, it'll increase your sound quality and decrease hissing sound by 70-80%. overall good product easy to install. Heat sink is not good. Edit after 2 month of use - I used it for new year eve for like 5-6hr continuosly at 70% volume and now it's gone, not working anymore.

Superb 4440 board
Superb 4440 board . Bass and treble has good range .Quality of sound is excellent . Should be installed by experienced technician or under guidence of experienced technician. Nuts for the controls were not shown in the pictures so I cannot complain but it would have been good to have the nuts. Thanks to seller and Amazon .
