port noise? distortion?

You have a prefab box that is 6 cu ft in size?  Any way you can link to it?  Starting back at square one and building a custom enclosure is most important if you are to lick these nagging problems.

Since you have not corrected whatever phase issue you have, open your enclosure and ensure your wiring looks like this (for a 1-ohm load with 2 DVC 4-ohm woofers):

i would link to it, but i bought it off of ebay. i know, its pretty big for a prefab.

i know one of them is wired in 1 ohm, i guess i was pretty stupid when i just assumed that the other one was also.

Sine it is a mono amp, you may use one set or both it does not matter.  Have you checked the wiring on both subwoofers and ensured it is like the image I posted?

yes i did. both are wired correctly to make it a 1 ohm load. im stumped. i guess ill try switching the other speaker's pos and neg wires around? i only switched one of the speakers wires the first time. any one have any ideas?

well, i've already set the gain, and it is plenty loud. it sounds as loud as it should without any distortion. its just that the speakers move opposite of each other. other than that it's fine. you also kind of lost me when you said 4 of each positive and negative wire. i have 2 positive (1 from each speaker) and 2 negative (one from each speaker) wires, and each of them are going into their own terminal. so, essentially i have 4 terminals, with 1 wire going into each one.

i really appreciate that help and patience.

I thought you said your speakers were DVC.  What is the make and model number?
