WANGCL 2 x 160W + 220W 2.1 Channel TDA7498E ZK-HT21 Bluetooth Digital Power Amplifier Module High and Low Tone Subwoofer

This little guys is very powerful.I have connected it to my car speakers 10 speakes plus 2 subs. And it does a greate job. Only complaint is the notification sound it makes when it turns on or when device is connected. That being said, the sound is very clear with nice bass.

Using it with a boombox. Good power especially when playing through USB. Works well from 12V DC.

This amp has some fan noise. The fan starts up on a signal coming through, it's not loud but when there are quieter sections of music you can hear a very faint whirr. Not for the avid audiophiles but fine for me. Bluetooth works fine and the amp has plenty of power with a 24V power adapter. Consider this amp if you need a small budget bluetooth amp with plenty of power.Update March ......I found the fan noise annoying as it stops and starts on signal input so I disconnected the fan from the board to see if the heat sink got hot only to find that there appeared to be faint whine coming from the speakers. I've now gone back to a previous underpowered amp as the noise is annoying.Further 1 week after purchase ...I've reconnected this amp without the fan running. The other issue (the whine) isn't apparent at the moment but we shall see. Hope the unit doesn't overheat without the fan running but I will monitor it.2 days later ... the whine is back and is irritating. Swapped out the power supply to a 12v 2amp adapter that I had lying around. It's been on for day and so far so good. The power seems adequate and it's not overheating either the amp or power adapter.Pros ... decent sound, good power, bluetooth, good control of the subwooferCons... noisy - fan & speaker noiseConclusion. If you want to blast out music it's fine, you won't hear the background noise. But running it from the TV output you'll hear the fan noise unless you disconnect it. And be careful what power unit you use.
