Phase?
My amp has nothing to change the phase and niether does my head unit but i heard that if i switch the positive and negative on my sub that that will reverse the phase, am i right? 
thanks guys
thanks guys

Yes...do this on all subs to reverse the phase.

Rep Power: 313 Well that all depends on the sub, the shape of the trunk, what way the sub is pointing and the type of enclosure your using. Putting the subs out of phase dosent hurt anything as long as you do the same to all the subs, not just one. Play around with it and see if it sounds better to you.

Rep Power: 328 Phase - The relative position of two sound waves with respect to each other.
Reversing the phase does the following:
1. Phase reverse actually means *invert the polarity*. So bits of the signal
that were previously positive going are now negative going and
vice-versa.
1A. At the points where the air pressure should be increasing, it's now
decreasing, and vice versa. So the compressions get replaced by
rarefactions.
2. In the electrical wave which is the analog of the sound wave, what were
formerly positive excursions (increases in voltage) are now negative.
If you look at it on the screen, it's the vertical mirror-image of what it
used be.

Rep Power: 0 A speaker moves OUT when power is applied, when you swap the leads the speaker moves IN instead.
Amps create sound through speakers by switching the power back and forth very fast.
Speakers are marked w/ a + and - on the leads to signal which way to hook up the leads to move the speaker out when power is applied from the + to the - lead.
When you have more than one speaker, you hook them up according to the +/- leads so that when powered they both move in or out at the same time. This way the bass adds together. This is the concept of phase.
In phase = all move out at the same time
Out of Phase = one speaker is moving in while the other is moving out
There is no set rule. Most times you start by putting all speakers in a system in phase w/ one another. Sometimes in certain vehicles bass sounds better when the subs are out of phase w/ the highs up front. Something you just have to try and see .....
