i didn't bother reading past the 1st page but the large number of inaccuracies and false statements is astounding. someone who actually knows about car audio should go over and take out all of the incorrect and false statements.
A.-if you want a little bit better sound, go for speakers with less ohms. This will mean you will lose less power/watts between the amp/head unit and the speakers. Also means better sound quality. Also consider what watts you will run the speakers at. It would be a waste of money IMO to buy speakers with high watt ratings, and not power them very high. You could also add a cheap aftermarket head unit for a little gain. If you only want a little bit better sound, you might want to stay cheap. Its up to you.
How to achieve good sound quality: The most important thing is to make sure your head unit is equiped with time delay and that your delays are set properly. What time delay does is it puts a delay on the sound coming from the closest speaker to you so that the sound from each speaker hits your ears at the same time. This can make a huge difference in the higher freaquency ranges where there are only fractions of a second between when the sound waves contract and expand, that time, by the way, determines freaquency.
inaccurate and partly false:
speed of sound at sea level = 340.29 miles per second
1,129 feet per second
so .001 of a second is = to 1.129 feet
so if the speaker is 4 feet away from you it takes roughly .004 or 4 thousandths of a second to reach your ears from speaker...
now if you other speaker is say only 3 feet away it would take .003 or 3 thousandths of a second for it to reach your ear.
the difference in this case is .001 or 1 thousandth of a second.
the human brain can't tell the difference of a .001 of a second difference in sound. and since we are listening in stereo each ears will be receiving different sounds regardless. as it'* not mono...so what does it matter if it doesn't reach our ears at exactly the same time?
i guarantee if you set up a room, chair in the middle and two speakers in optimal equidistant from them selfs and the chair and had one speaker sending even .009 music/sounds behind another speaker playing a song/note/sounds no one would be able to tell the difference or which speaker was sending the sound slower or any difference whatsoever...
Time alignment it'* important in big amphitheaters and the such where you have thousands of feet between speakers and such.
the high end SQ HUs that win iasca don't have any time correction. it'* a marketting gimmick.
all i'm saying is you guys need to clean up this thread BIG TIME.
i advise using this website as i guide before anyone posts anything: http://www.bcae1.com/
i know how you all hate inaccuracy and this thread is FULL of it. i'm guessing on the next page i'll hear about how great capacitors are.
