4 speakers vs 8 speakers

yeah... but its a lot more noticable in the lower octaves than in the mid to upper octaves.... I reccomend against people doubling up on most speakers.... subs to a lesser extent due to the frequencies they are playing are harder to cancel out due to the longer than cabin size of the wave lengths.

But it is possible to set up a pair of rear speakers to sound very good too, if you have a reason to invest the added expense and time to do so. It's far more expensive either in time or seperate equalizer components for the rear and front than just slapping a good pair of speakers in the front and calling it a day.

Exactly.... MORE WORK to make them sound as good. 90% of people pay to have a shop just lazily throw 4 speakers & a deck in their car.... 8% will do the lazy install themselves, and about 1-2% of people will pay for a well thought out install, or actually do it themselves properly. Obviously most people don't put in the time for a proper 2 speaker install, so why would they want to put in even more work for a 4 speaker install?

4 speaker setups have a lower SQ potential than 2 speakers, UNTIL you start getting into DVD setups.


Also.... I went to the Official DB Drags website.... and here's what they show for the loudest vehicle ever..

Its in the 3+ subs category.... the single woofer category wasn't nearly as loud.
