These are excellent little amps. You can add a blue tooth module and amplify about anything. I used one on my old flat screen TV to improve the sound. They are small and an old laptop power supply works great to power them.

It meets its power specs. I like that it includes a shielded analog signal input cable. It has input signal attenuators for both channels but the gain of the amp itself is fixed and quite high. It would have had a better signal-to-noise ratio if the gain of the amp itself was lower.

This little guy packs a punch for it's size and cost. It has nice sound quality too, I got it without a real purpose in mind. I was installing a system in my car and wanted some options if one component was lacking power, didn't need it. Ended up using it to rig a Bluetooth amp for my guitar. I used it as s preamp from the guitar to the bt transmitter, this is a very weak signal, and a lot of amps wouldn't have recognized the signal, it sounded great, like tube amp great (I'm no expert, but the first remark anyone makes when they hear it it "oh my god, it sounds really good"). I also put it on a set of 12" 3000W Kicker L7s, now I'm not saying it did the job, but it pushed'em, loud enough to have been a home theater subwoofer in a medium sized room, I was just playing so I didn't even have a low pass filter set up, so it was amplifying the full spectrum and getting 90% of that filtered by the subwoofer protective filter and still it wss impressive considering 1800W minimum is the manufacturers suggestion for them. Only con for me, no power button, but I just wired a toggle switch on the dc voltage line and am happy with my $12 amp.
