I think you would reap much benefit from tossing a small amp dedicated to the subwoofers in the mix. You can get a nice Audiobahn amp for less than $100. Like this one for $88 which is overkill (400x1 or 200x2 or 2x100):

It has built in crossover, so if it would be possible to return the crossovers/coils/whatever that you used, this will do exactly what those are doing

If that's just too much money for you, you could get this one for $69 (1x200 or 2x100 or 2x50):

Or you could consider buying one of the $88 amp (for subs) and one of the $69 amps (for mids n highs). You just can't beat that for less than $200 and from a reputable brand like Audiobahn and a store like H-O-T.

If you're on a super budget, I might be able to find something cheaper for you. I'd just hate to see you nuke your subs or something.

If you do choose to get either of these, spend money on the proper wiring. If you are on a budget, this kit is suitable for one amp @ $25:

Be sure to use the inline fuse.

If you got a few xtra bucks to spend and want a higher quality kit, I prefer not using Monster Cable, something like this Rockford Fosgate kit for $38 is much, much higher quality and better:

Again - fuse it within 18" from the battery for safety's sake and be sure to use a rubber gromit at the firewall to prevent your power wire from getting cut and shorting out.
