I am changing all the stock speakers and need some info and advise from you guys. Im a noob with this so bear with me....

Anyone have the Stock HU's power output for an 04 MCS? Couldnt find it anywhere and what Ohm speakers do I need?

What size speakers fit the the front doors without sawing anything , brackets,etc.. I have seen 5.25 and 6.5 on different threads. Anyone know for sure?

Anyone know the speaker depth I must stay under when online shopping?

I love to blast my music on the highway with the windows down so loud and clear is important.

I also like feeling a reasonable amount of base notes. Not gonna do a sub and no new HU (I really want to avoid HU change if possible).

Thinking of:

INFINITY REFERENCE 5022 (if 5.25" go in front vs. 6.5's)
45 Watt RMS/ 135 Watts

INFINITI REFERENCE 9623I
100 Watts RMS / 300 Watts
* big difference between 3way & 2 way in sound?)

These good? not good?

I will want to power "whichever" speaker I go with with an amp.

Any amp power specific suggestions for the Infiniti Ref. combo for 6x9 & 5.25's?

How about 6x9 & 6.5 of the same line?

If an amp is only powering the 6x9's, will the stock HU be able to "give" the 6x9 watts to the front 5.25's so the fronts will run on stock HU power but more than before?

Price range $450-$550 or as close as possible.

Thanks!
