TDA7498E Bluetooth Amplifier Board 160W×2+220W Subwoofer 2.1 Channel Audio Receiver Power Amplifier Module with Treble and Bass Control for DIY Speakers

We built a boom box powered by a Ryobi drill battery using this module. Lots of BOOM for the buck. It's pretty stupid proof. It runs on 4 / 8 ohm speakers and cranks on 18v pack. Make sure you have some ventilation for the unit.

Power supply of choice is lithium (with beryllium laced liners). Additional dash of oxidized cadnium. Resulting effect alternate can only be seen by Blaupunkt. Almost sin.

I have an old farm truck that didn’t have a stereo so I bought this to put in it. I run 4 speakers (two speakers per channel) wired appropriately and a 10” subwoofer. It’s running on 20v through a 12v-20v step up. Super loud. Bass from the subwoofer is pretty powerful for how small this thing is. Sound quality is clear and overall pretty decent. The reason for 4 stars is because the “frequency” knob that is used to adjust the pitch of the subwoofer doesn’t seem to do anything. I have used other amplifiers like this one before and that knob does create a minor but noticeable change in the sound of the subwoofer. Not really that important though and works great otherwise.

Assembly required though it only took me a whole of five minutes or so without instructions. It's surprising sturdy for its appearance. I've got this amplifer connected with a 24v source and it's sound quality it provides to my two high RMS 6.5" speakers is astounding. It will almost deafen you with the capability of its power output. With the convenience of bluetooth, USB, auxiliary in, the adjustable treble and bass. It's a far better alternative to those higher priced amplifers that have lower power outputs and claim to be high quality. This amplifier is solid and I plan to purchase more of this sellers products as they have many applications and are very lightweight and portable.

I’m impressed with this little amp board kit. The only gripe I’d have is the little fan barely making noise but that’s nit picking because it’s whisper quiet.Back to positive feedback.1: Driving retro JBL speakers from the 80s with 5 1/2 inch drivers. 150w 8ohm. Sound perfect.2: Bluetooth links with Apple TV4k. Flawlessly3: Driving 2 40w exciters with 1 50w shaker from sub channel. (Have to turn down gain and volume still).4: Links to iPhone flawlessly.5: Sub channel has separate volume and gain.6: bass and treble have separate gain.7: Volume control.8: Quality heat sink.9: Plenty of power to drive power hungry 80s speakers.10: Tiny footprint with plenty of undistorted sound coming from speakers.11: Quality capacitor array.I’m honestly impressed. My recliner rock and rolls and I’m only using 16vdc @4Ah and I could add 1 more bass shaker easily. If I turned up the gain and volume on the sub channel I’d blow up chair.

It’s ok. Not sure about the wattage even with the highest recommended power supply. I have to tweak my EQ settings on my Pi or it’ll shut down when up. If you just need something that you don’t plan on pushing some watts it should do.

Easy to hook up and powers my 2 6.5 marine speakers well in a homemade Bluetooth system.

Powered with a 24v 6A power supply and connected to a pair of 8" ceiling speakers and an 8" passive sub. All 8 Ohm speakers. It worked great for the first 30 minutes or so then I noticed that the bass was gone and the speakers sound distorted. I checked the power supply it was fine. I unplugged it for 5 minutes. Plugged again, the sound quality improved a little bit then 5 minutes later, it got worse than the first time. Now you can barely hear the speakers. What a waste of my time and energy. I tried to contact support, so far no response.
