weird stuff

to make a long story short i've been bassless for the past week or so

so it's forced me to pay close attention to my mids & tweets which today revieled a pleasant surprise

remember no subs this is just door speakers

I changed the balance on the HU to full left and i noticed the bass response was alot tighter then when i balanced out left and right

the same happend when i put the balance to full right, the bass was much tighter then when the balance was even

so i swapped the positive and negative speaker wire on the right channel of my amp and BOOM the bass was deep and clear even when the balance was even

now i'm almost positive that i followed positive and negative all the way from the amp to the speaker when i first installed everything a couple months ago

if i did, that would mean that i now have a positive on my amp going to a negative on my speaker (which doesn't matter cause it sounds a thousand times better now)

does this make any sense?

Sure does. Sometimes swapping phase on one side helps response by eliminating cancellation. Since the speakers are fairly far away when they are wired "in phase" cancellation can happen by the time the signals reach each other. Just like if they were "out of phase" and close together.

as you found out, your mids were out of phase.

as to the cause, i hate to say it, but it's probably an install issue. i'm sure it could be traced back to the wiring. not to say the amp could be marked wrong, or the speakers, that's a possibility, but i'd wager it's install.

without subs, alot of one's hig end is revealed..

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

or what jacob said, lol

There are two kinds of phase: absolute and relative. Absolute means that the speakers move together. Realtive phase means that the signals from the speakers are in phase when the sound gets to your ears. This will vary with the position of the speakers and where your nugget is in relation to the speakers. Many times in absolute phase is out of relative phase. Relative phase is what you hear and what matters.

man i love this place, it's so easy to learn stuff

so what about subwoofers

i have two but they're running off a single channel amp, is it possible for them to not sound right even if they're in absolute phase?

Due to the length of the soundwaves at the frequencies a subwoofer is reproducing, as long as they are in absolute phase they will be in relative phase in a car environment. In a large room like an auditorium there will actually be "boomy" and "dead" spots b/c the woofers are in and out of phase with each other.
