Anyone used a kinter amp with usb?
I am working through some ideas and found a kinter MA-150 amp that appears to have RCA inputs, and speaker outputs as well as an additional USB port for charging devices. Since I am looking to use my Windows Mobile phone to run my system the USB power could be extremely helpful. I realize I will need a secondary set of speakers to have my stock radio run and this at the same time and I thought this might be an option.

Thoughts??

Beware of Kinter and similar amplifiers
Kinter is trying to sell a small 2 x 8.5W amplifier marked 500W. I have recently opened one of these amplifiers and I found a SANYO LA4508 integrated power amp inside.

See datasheet:
javascriptpenreq('http://www.datasheetcatalog.org/datasheet/sanyo/LA4508.pdf')

This amplifier is actually specified for 24VDC and gives only around 2 x 3W at 12V.

After what I can see there are other brands with similar products looking almost alike the "Kinter 500W". I doubt that there is any big differance inside.

Regards
Bjorn

Yeah, they probably did. The 500W is never mentioned as an actual power rating. It is just a part of the product name, which is very misleading. However in the specs they say 2 x 75W rms and even that is a big lie. On the product itself the terminals says: 12V and .5A . If I calculate the maximum power that I can put into the amplifier it is 6W ! And that corresponds very much to what I get if I feed the amplifier with a sine wave just before clipping. They are probably surviving of the fact that most people are not engineers of electronics. And the engineers are building their own amplifiers, so they are not the buyers.
