10w class d amp. application note

I have looked for class d amp solution for a battery powered amp (12V car)
for playing in the street, with my bass guitar.
Since I don´'t need very much power
I was thinking that this circuit used in bridge mode If posible?
could be used . since it's not a hifi amp im trying to build im not worried about small high freq distortion.

The resom im interested in class d is because I think the battery will keep longer and that I have read that class d offen's good at reproducing bass freq.

Ofcause it will be very easy to use a TDA IC for normal amp solution. and proberly it will be waist of time to diy a class d amp for use in the street.

But still I would like to hear some coments on the idear.

best regards jc.
