TPA3255 600W Digital Power Amplifier Board High Power Stereo 300WX2 Bridge Mono

I decided to resurrect an old speaker box with a recent purchase of a 12 inch dual coil subwoofer element. I found this amplifier, used it with a 24VDC 15 amp power supply and it's worked fantastic!10 months later of some moderate to heavy use with my 7.1 Atmos Home Theater system, no issues whatsoever.

Worked great for 2 months, then started getting noisier by the day.It has now become too noisy to enjoy.

Where do I get the white 3 pin connector for it? No information given on it.

Board works. With 8 ohm speakers on medium volume it pulls just about 2A current from 48 volts power supply. Will test properly on 4 and 8 ohm loads and update review. Fan in auto mode kicks in at 100F. Cooling down fast and switching it off. Going to increase heatsink and get rid of fan altogether.

I am using this to add high power amplifier sections to a low wattage tube bass guitar amp. Using a Drok 10A DC supply @ 48v, this pushes enough current to drive a 4ohm 4x10 Ampeg cabinet loud enough to play with a drummer and have a decent amount of headroom leftover. Oh, and a second amplifier leftover too.Main complaint is there's no spec for input level, so I had to guess where to set my driver board for minimal distortion and failed frequently as I was trying and erring.Also, screw terminals or RCA jacks would be better than the little 3pin connector for line input.Lastly, as this is a Class D amp being powered by a switch mode power supply, you need to be very careful with grounding to avoid ground loop and SMPS noise.

Some of these amp boards suck these ones do not, no swelling blown up capacitors or burn holes in the Ic's everything is labeled on the board in English

Very good amplifier. Crystal clear sound.

Needs a beefy power supply but the sound and output are great.
