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

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

Did not work-never received refund
My $70 outdoor mini subwoofer amp that I’ve used for years went out so I decided to get something “higher end” to replace it this time around. When I received this amp and connected, my sub barely had any sound coming from it and had a static sound. I changed all cables and same issue. I thought it was my subwoofer but decided to buy another amp for $70 that another comment recommended and my subwoofer worked perfectly. I sent this item back on September 7th and it shows they received it September 9th and I have yet to receive a refund. I called twice and both times Amazon cust service said they see the refund sent out and I should receive in 24 hours but I have not received it yet. So still out of my $400 paid for this amp. Would not recommend.

Not Sure…
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.
