Hi LF

I have read about using old TDA2010 audio modules as exciter stages fo= r LF amplifiers

Searching the web have found that there is actually a bunch of cheap a= udio amplifiers based
in TDA7498 which is 2x100W. I wonder if this worths to get some watts = into LF. Mat be the
two outputs can be also combined if feeded ati phase ?

Have a look at one of this here
