All the small amps I see have around 20 watts real power . is there an affordable small 2.0 amp I can get for under $100?

I would look at the Dayton APA-150. It's a great little amplifier. I use it to power some zone 2 speakers in my garage. It's a little more expensive then $100, but not by much. It also makes a lot more then 20 watts.

Thanks. I am open to the used market too or going a little over $100 if its worth it BUT worth it means a lot when the 20w ones can be had for sub $30

Also that Dayton only puts out like 40 realistically for 8ohms so its not worth the extra $110 for this non critical application

The output wattage for that Dayton amplifier is said to be underrated on the published specifications. From my experience using it I think it does produce more power. But for your particular application it still might not be worth it.

My other concern with this is the reliablity. There are a lot of complaints about them breaking down.

The way I see it I need at least 40 watts (1-2-4-8-16-32) or 70 watts (64) for the added headroom.

The speakers I plan on using are pretty insensitive but I also don't need a ton of output.

20W should be enough for most applications in a smaller room, if your speakers are reasonably sensitive.

Here is a calculator to give you a rough idea: http://www.hometheatrebasics.com/home-theatre-tools/spl-calculator/

There are a whole bunch of cheap Class-D amps on Ebay and Amazon which should be more than adequate. There are also some that would put out more power, but without knowing your environment and speakers, there is no way to tell if you need it.

As far as reliability..., for $50-$100 you should be able to get something that lasts for a while.

I still have a 100WPC Tripath Italian-made amp, which has lasted for about 3-4 years now (although it cost something like 400 Euros back then). And that's an Italian-made electronic device.... biggrin.gif

I think I'll forgo the subwoofer and just throw in a couple speakers it can't be too bad for bass
