    It means when the subs are wired different from each other. It means one sub has the positive wire on the negative and the negative wire on the positve side. So it means one sub is pushing when the other is pulling, in simple terms one sub is going outward when the other one is going inward, just reverse the wires on ONE sub only so they are both doing the same thing at the same time. If they are out of phase it should make a big differance in output.

    I see your pic you only seem to have one sub, look on your amp. there should be a switch that shows 0 or 180 that will switch the phase of the sub. From your description I dont think that is your problem. Can you give a better description of what the problem does

    it seems the bass is delayed in some music,but not all. I was just reading the subsonic shouldn`t be on in sealed enclosures& i haven`t tried to properly set gains, lp levels or anything like that yet. Or could it just be bad copy of music?

    yeah, if you have a sealed box then the subsonic should be off.. LP filter should be on at least 80hz.

    on some songs, the bass is delayed. I've noticed that too with mine. prolly crappy recording or something especially with MP3's. Do you happen to have time alignment or speaker distance setting on your deck?

    no,
    is it something to do with a shortage of power?

    no, time alignment or speaker distance setting on your deck is to set the timing of the music to make sure everything (like bass) hit at the exact same time. some stereos have this feature but others don't
