Title: Mame sound amp
Post by: acidblue0 on September 21, 2009, 09:48:33 pm

Almost done with my Mame cabinet. All I got left is sound and bezel. It has a left and right speaker on top. Whats a cheap little amp I can use to power those speakers?

20 bucks aint bad, thats probably just about the right size power wise too.


most of the amps in a cheap pair of speakers will be the same.. probably around 2-4 watts.

look for a little DIL chip.

you can sometimes find cheap speakers for a few bucks.. that would be the most economical way of getting a small amp.

I don't know how the Sanyo D-amp is, but the Philips/NXP digital amplifier chips are pretty good. This one has a 2x70 watt TDA8920
This is the data sheet of the current model

I got it pretty fast delivered from Thailand.
