how to wire this system?

Use the one deck, the DVD with the three outputs and aux inputs.  Instead of trying to also use a CD player, get the proper CD changer and plug it into the changer input on the deck.  You want just one main head unit for your system.  And can't you play CD's on the DVD player anyway?

Post a link or provide coil config. for those subs.  Nobody can guess what impedance they are to help you out about hooking up to the amp.

A four channel amp can drive 6 speakers only if two pairs of those speakers are separated by  crossovers.  The 5.25's you said were wired with the tweeters:  are they connected with crossovers?

The dvd receiver is just a receiver...no sot to insert cd/dvds.  The subs are single coil and 4 ohm stable and they are rated at 500watts.  Instead of using the JBLs I decided to use four Polk Audio 6.5" - two in the back and two in the front.  The tweeters have a built in crossover.  If i wired them together (tweets and 6.5") they would be okay?  So it would be like this...

Channel 1 - back left speaker

Channel 2- back right speaker

Channel 3 - front left mid and tweeter wired together (in series?)

Channel 4- front right mid and tweeter wired together (in series?)

SUBS

Im thinking of wiring them in parallel and bridging the amp.  The amp puts out 460 watts with all channels full power at 2ohms.  So if I run two 4 ohm subs in parallel that drops them to 2 ohms, right?  Then bridging them will get full power but still within the limitations of the amp.  Am I okay doing this or am I way off?

THANKS!

A bridged load can be NO LESS than a 4 ohm load, which means with your SVC 4ohm subs your better bet is to use a mono amp instead of the two channel amp you want to use.  Given what you have to work with, you will need to wire the subs in series and bridge the 8 ohm load onto the amp.

Look at your amp's specs and you'll see that a 2 ohm load is not listed as a bridgeable load.

Mids and tweets with a crossover:  the xover itself gets the signal from the amp, then splits out to the mid and tweet.  You are not wiring either series or parallel when you separate components by using a crossover.  The impedance of each will be maintained. 

??  Im not using a component system.  I have the POLKs which are 2 ways and then I have my tweeters which have built in crossovers.  How would you wire this?

This might make things a bit easier to understand...

Can you provide manufacturer and like ID for the products you have? Like model numbers?

You are definitely having trouble getting across what exactly you have. You are saying you have a mid and tweeter wired together but they aren't components, when that's exactly what they should be... a 2 way component set. Another way I can kinda read is that you have 2 pairs of coaxial speakers(4 6.5 speakers with mids+tweeters) and 1 pair has a 2nd tweeter wired into the mid... Which well, I've never heard of but who knows... I'd say Model #'s and such will be useful.

Actually components are called 2 way as well... Atleast marketted that way. :P Anyways, I'd say stick with similar product lines unless your JBLs are much better. (I don't know the quality of JBL product.) Otherwise scrap your Xplod tweeters and stick with just 4. In which case very easy, wire 1 channel to each speaker. Which solves the dilemma you are having there. Getting components I do not believe would have made this any easier for you. Especially since you are still learning here.
