Witch is the easyest way to make a dc dc converter from 12v to 40v?
Thanks.
 

Use something like the LM2577 (dc-dc step-up converter) ..

And witch current is MAX? i need about 2A
 

Use this link and design you DC-DC converter for 12 -> 40V 2 Amp.

Can i use this power supply in car,for amplifier 2*20w?
 

Yes you can but make sure you input can handle 60+ Volt and also put a transzorb at the input of your powersupply of 1500W @ 24V so that spikes are not killing your design. Car powersupply is sometimes called: "Power supply from HEL" and this is not for a reason !.

Use a switching frequency that is 100K or higher and high voltage MOSFET's. The high switching frequency is since you use an audio application !.
