A few months ago I recieved an interesting speaker as a birthday gift:

It's made by hong-kong artist jason siu, and has a 150W max. not owning a home stereo system anymore, I was hoping to use it on my computer (via headphone port) I bought a Y-adapter to run from my headphone jack to the speaker's two jacks (red and black) and the speaker put out a clear, but very quiet, sound. A guy at tweeter audio said i needed an amplifier to power it, but stated he didn't know of a price-practical audio amp that could power the speaker. I believe he said I should look for something around 50 watts. I've been searching for a while now, but everything i find seems too powerful or has way more inputs and options than i need. I need a simple amp that can be powered from a wall jack, plug into my computer's 1/8" audio port, and drive a single 150w max speaker via it's 2 red and black 4mm jacks. any suggestions? will a car amp work? (they seem to be relatively inexpensive) Any advice would be greatly appreciated.
