so from what I read you really want
mid high amp
radio
cap
enclsure
sub
sub amp
you also had some superfalus crap in there like a very cheap EQ. Usualy, you can save that money and put it into a better radio to get a EQ built in. Also, most decent qualtiy amps, come with a remote bass control knob which is nice.
For the 650.... your simply not going to get all that with good quality components... This is what I came up with for that stuff in a resonable price.
Mid / high amp:

Built in 7 band EQ. And VERY IMPORTANT 3X RCA outputs (front / rear / dedicate sub) seance your gonna amp everything. Also, built in iPod control for no extra cash.

Good cheap subs, these are last years model, but still new so you get them at a steal, all they changed was the look.
Sub amp:

HiFonics budget priced gear, good amps, great price per watt, and you will get alot closer to true advertised watts then with cheaper brand.

I just like these and the color scheme matches your amps.
Youll need to buy enough 8ga. as well to run from the dustribution block to both amps and a cap but that covers pretty much everything.
The mids and highs you got are not good, but there better then stock and will hold you till you get some more cash.
All this costs : 780
Thats why people though you were stupid or silly trying to get so much for so little by going with junk brands. These items are pretty much the cheapest I can recomend to somone trying to get so much out of a system. Keep in mind, this also doesnt have a box included.... seriously, if you have a drill you can build your own box, it will be cheaper and alot louder. Lowes or Home depot will usualy do all the cuts for free or next to nothing.
