I have one 12" MA sub that's running off of an older kenwood 250 amp. Upgraded the big 3 and still notice lights dim when sub hits hard. Been pulled over once for "flashing" my headlights!!! Do I need a cap, even bigger power and ground wires, or just need to try something else all together?

What size power cable na d ground are you running? Did you meter your ground to confirm it is infact a "quality ground"? Also make sure to chack out vehicles factory grounds.

One word... A-L-T-E-R-N-A-T-O-R
Whether you have 50 watts, or 50,000 watts, if your lights are dimming, your power source (your alternator) is too small. Period. You need a bigger one.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Take Haemphyst's advice, it all starts at the alternator. If you don't have enough power there you can't increase power with a cap and bigger wires.

From what you described (as far as gear) I don't see why there is a power starvation problem unless there is something significantly decrepit with your car's power system.  I too have an 01 Taurus and original alternator, with no starvation problems...probably running about the same load as you are.  Make sure you have a new or recently purchased battery that has not gone dead a few times.  After that, check junkyards for a replacement alternator.  There are a lot of these Taurus models available and shouldn't be hard to find or cost too much.
Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
