SMP300 Class D Digital Subwoofer Amplifier Rated at 500W Max

Bought this to install in a Friends Bar / Lounge. This was my First time dealing with 70V System, I have to say its pretty Dang Good for Hanging Subwoofers Amp. Only wish it had more power for the price.

Very pleased. Its works well with my SONOS Amp and it drives my outdoor subwoofer. Great bass in the pool courtyard.

I bought this 300w OSD and one of those cheap less than 100 bucks palm sized amps. The two were VERY similar running the OSD 10 inch outdoor sub. The OSD sounded slightly better, maybe a bit more punch, and tighter. However, the price difference was 300 dollars, therefore the OSD was returned. Positives - Seems like a very well built product. Controls were smooth and all connections were tight. It’s packaged from the factory very well.

Good product but the OSD speaker didn’t work well with it. Will have to change it out. But pleased with the item.

Used as sub for addition to a 2 Channel stereo
