Need to design a simple 12v delay

I am working in a vehicle that has a fairly elaborate stereo system.along with all this equipment came a bit of noise.It appears the noise is being generated from a processor that when powered up goes through a start up sequence.As soon as the proc. stops the start up routine the noise disappears.i believe i just need to delay the turn on of the amps by a few seconds til this process passes.all devices turn on with a couple hundred mA so i believe i should be able to delay the amps by 2-5 seconds and be fine.

any ideas?im a noob about circuits and im sure there is prolly a device avail that can accomplish this but im interested in designing something if doable and fairly cost effective.

thank you
