I have a Phoenix Gold MPS-2240 amplifier that's in good, but not great condition. Either way, it works!!! :D My situation is, after looking up the owner's manual and seeing the extreme flexibility that this amplifier has, I need some help with inductors and capacitors.
My questions are:
What is a good source to get these inductors and capacitors that I need?
What are some suggestions/advice on to-do's and not-to-do's?
Should I wire them into a "board" or wire them in-line with the speaker wire?
How resilient are these capacitors/inductors as far as bass, bumps, and longevity go?
Any help is appreciated. I want to run 10awg to all speakers. 4awg to the amp power. And, I plan to take pictures once I'm done. :)
This is close to what I want to accomplish:

THANKS EVERYONE IN ADVANCE!! I'm really stuck right now...

A quick word about using capacitors... unless you're building a magnetic igniter system for a high wattage lamp, don't make it a first thought.
Inductor wise, I'm trying to decide what you want to use them for. There are thousands of types of inductors, from various forms of line filters, to magnetic isolator systems... I can think of a billion ways to use inductors, most for filtering purposes. What has you thinking you need these, and where?
Your concern for a capacitor is slightly misguided. It will not help your power supply issues. See the Upgrading the Big Three post concerning how to upgrade your charging system, giving you a better power run to this amplifier.
Are you dead set on using this one amp to power EVERYTHING in your car?

Thanks for the quick reply!
The thing that got me thinking that I was going to need inductors and capacitors was the actual owner's manual for the amplifier itself. I have used "bass blockers" or passive crossovers before, but never have I had to build them (or put them together) from scratch... Have a look for yourself and tell me what you think.
Original owner's manual:
ftp://www.rodinaudio.com/Phoenix%20Gold%20Mobile%20Audio/Manuals/Amplifiers/MPS2240%20manual,%20full.PDF
After reading the whole manual, yes, I became intrigued by the idea that I could run my whole system off of this two channel amplifier. I like to do this type of things in my vehicle to make it original. My first idea was to buy a 4-channel amp that would fit under my passenger seat and a small sub amp (either mono or 2-channel) and mount it to the rear seat. If I can accomplish all of this with this one amplifier, then that is what I would rather do. It would actually be perfect!! Anymore suggestions or comments are welcome!!

Okay, that's what I figured you were wanting to do.
I'll be honest, it doesn't sound like you do this everyday (and by do this everyday, I mean build circuits)it may be in your better interest to simply buy two good amps and go that route.
Powering everything from one amp can be a really tricky thing as you have to balance out your ohm load across the left and right side. Too much resistance on one set of rails versus another could spell disaster in various forms quickly.
But, let me give you somethings to chew on for a while. To the left of the screen there's 75 internal links (Yes I counted) to various parts of this website. There is literature there regarding various forms of crossovers, both active and passive.
If you decide to take the one amp approach, take your time, and ask lots of questions here. You want to get it right the first time. You could buy the crossovers and things from various manufacturers, you could build them yourself, there's various ways to hook up the speakers that will alter you resistance present to the amplifier, which will affect the performance dramatically. (.16 ohm and 16 ohms cause two VERY DIFFERENT reactions from amplification circuitry)
If you wanna do it quick and simple, get two separate amps and perhaps make this venture a hobby for later completion.

Though what I said holds true, I'm actually curious about varying ohm loads across bridged rails like this... DYohn, Haemphyst, 12volt, Jeff Chilcott (10 other people who I have a lot of respect for)... anyone?

I've done all types of installs and my ohm's law, relays, and electrical are all very well versed. I've even dabbled in potentiometers. Just never had this situation. I want to "make sure I do it right the first time". Trust me, wiring in series versus parallel is not my question here. It's more of where I can find a good source for the type of inductors and capacitors that I would need for this type of circuit. And, yes, another question is whether I'd be using a circuit board or wiring in-line with the wire.
I understand the MAJOR difference in 1 ohm and 10 ohm. This amplifier was built to handle .5 ohm in mono and 1 ohm in stereo. I want to use this amplifier for the type of circuit that is demonstrated in the owner's manual. I have never seen a inductor sold by itself. I am just asking if maybe someone else out there can point me in the right direction in acquiring these supplies so that I can get started, preferably someone who has wired a system like this so that they may be able to give some insight on certain situations to avoid and what not. Thanks again.

Thanks for the links! That should get me started!
See. Now my question is which ones can I wire into a 10 gauge wire and not restrict flow. Most of the capacitors/inductors that I see on those sites are very thin wire like 18 gauge.
And, still, whether to do a board or wire in-line. phoenix gold hookup extensive . -- posted image.
