I plan on building a custom box in my 04 saturn ion redline, in the back seats there is a center console type of thing and i want to build a box to house two 8s. But on another forum a member pointed out that it would not be advisable to put the subs in a box in the middle of the interior of the cab. This is what was said to me
That's not a good place for a speaker, especially an 8". It will pull the sound stage back from the front, and make it impossible to get good imaging, and present all kinds of phasing issues. Plus a woofer will suffer from cancellation bigtime in the center, best place for a woofer is in a corner, that way it's impossible to loose output from cancellation due to reflected sound waves. The frequency response from a typical 8" is mostly in the midbass range, and would work best in the front doors, then you can mount the midrange drivers in kickpanels to get a more equal pathlength to avoid phasing problems. You should make a kustom amp rack there, that would be sweet.
