But un precision power puts out 260 w lang pag bridged. Enough ba to for subwoofer?

Yes it is. Just make your subwoofer more efficient. A subwoofer's performance is way dependent on its enclosure more than anything else.

I can get a subwoofer, throw it in a ported 3cu.ft enclosure then feed it 300W to beat the exact same subwoofer but in a sealed 1cu.ft enclosure and feed it 1000W of power and still the 300W will be louder. Given this, it's best to simply optimize the design of an enclosure more than feeding it more power (which translates into lesser fuel efficiency btw)
