Well I am planning on building a crossover for an am that will go from the head unit's preouts to the amps rca in's. What type of resistors and capacitor's would I need and where could I get them? The level is 500mV and 1k impedance. I already have a calculator but don't know enough yet.

Generally if you want to put an x-over between the deck and amp you built yourself I would suggest doing active. I used to build a simple high or low pass x-over using a lm4558 dual op amp that had a simple regulator for a b+ of 10 v gnd of 5v and b- of 0v. I then built a simple 12 db butterworth arrangement and dialed in enough gain to make the pass frequencies about unity gain. I stopped building these things because x-overs like the Coustic xm-1 were to cheap to make it worth while.
