lm3886 for sub amp

[bego2]

serched forum and fined that lm3886 is good for sub amplifier.

i need some amp, about 100w rms to run 4ohm drive (focal 30a1 sub), can two lm3886 in parallel aplication run focal 30a1 ?

would 225VA transformer run that amp?

need some shematic, i found something but i wont aou guys to tell me, whats the best... many thanks.

To drive a 4 ohm sub, you will need two LM3886s or one LM4780 work in parallel.
Before it, you should fit a subwoofer filter of course.
Just one 160VA toroid will be enough to feed these amps..
That will give you more than 100W into 4R..

I use to sell a ParaPix Sub amp and there were 2000
of them, they are all gone and there is some information
and schematic on this page, near the bottom.
HTH's
They used 2 LM 3886T's

If require more output power,then go for BPA configuration which is using 4 or more LM3886s and bigger size transformer.
