is there a chip amp that will give me 50 watts of power

[merickrc]

i am looking to build a chip amp that will power these speakers http://www.zaphaudio.com/BAMTM.html is there a chip amp that will give me 50 watts of power per chan

What is the impedance of those speakers?

[merickrc]

8 ohms

LM3886

Yes, an LM3886 based chip amp with a power supply or around +/-36 volts should do. You may even get away with an LM3875 too.

thanks for all the help so far will this kit work http://www.chipamp.com/lm3886.shtml

merickrc,
I run a set of JBL L40 speakers, 8 ohm, from an LM3875 (56 wpc, I think). I am extremely pleased with this set-up . Plus, Peter Daniel (www.audiosector.com) was very helpful, very prompt with replies, while I was building the amp. I'd do another LM3875 without batting an eye .

Merickrc, this speaker uses 2 8ohm woffers in parallel so it is
a 4ohm speaker.

thanks for all the help

That's a pretty inefficient chip. A TDA8920B will easily handle over 50W per channel and is much more efficient. (Aside from lower operating costs, it also means a cheaper power supply and smaller heatsinks.)
