Im not sure if i have the 4-ohm or the 8-ohm, but i have 2x 12" kickers that look like this:

they wiring is done like this:

too be honest, the sound is okay. hits hard one some songs, but it doesnt rumble on the low notes to well
also if two different low sounds are being produced at the same time, the effect is almost a pain to the ears
i got the sensitivity and bass boost turned up to the point if i turn either one any more, the speakers would be too loud and distorted
i have it turned on low pass with it turned all the way up to 90hz
im really not to savvy when it come to car audio. what do you guys think of my setup? is it okay or do you guys have any reccomendations?
