Question Quick PCB question

I've been trying to route my lm4780 board, but the largest nets i can route with are 60mils. I know its best to use around 150 mils at the power inputs and speaker outs but how important is this. I will only ever be able to route at 60mils at the chip pins so would 60 be fine for the whole board ?

Any info would be much appreciated

The reference board may give you some good ideas. Check it out (it's in the datasheet).

Everything I have ever heard would suggest that 60 isn't going to cut it. But I'm nowhere near an authority on the subject.

But what would the effects of having the smaller tracks be ?
