power for crossover in car

[deriver23]

I want to build the esp crosover (schematic found here http://www.sound.westhost.com/project09.htm )
the problem is that the opamps require 15V could anyone provide a solution (i have looked at buck boost converters but have no idea which IC to use)

Use Rods design

Or run at 12v and use

I used project 95 on a TLO72 with no probs, I eventualy took my feed from my car amplifier. Inside I looked for the obvious area of power near its op-amps and found a dual 15v supply. Some amps I've seen LM series regulators in them, that makes it easier to find the voltage.

Hope this helps

There's little DC-DC converter modules you can buy, in a range of input and output voltages. Mouser has the NMV1215SC from C&D Technologies http://www.cd4power.com/
