Re: Audio nuts only

["Mike" <lerb@redrose.net>]

Well as far as the ba ck speakers get rid of them...a good system only
eliminates sounds from behind you anyways...I like to think of it this
way...Where do you hear voices from? In front of you right? Well every
single voice you hear from the back you wil have to over power from the
front. So why have rear? Only reason to ever have rear is if you have an
audiance in the back. Actually another reason would be if you were goig to
add a center channel but it does not look like you are about to do that. If
you don't want thump stay away from a sub altogether. I think a good set of
speakers up front will help your sound alot but I am not sure how you are
going to avoid thump. Our cars have whats refurred to as a megaphone affect
with the rear hatch reflecting alot of sound off of the glass and actually
enhancing the sound pressure forward in the cab which makes any bass
produced from te rear sound like thump. I have had people ask me what size
subs I had me when I only had part of my system installed in my car (4,5 1/4
Mb Quarts in the rear deck before I knew better than to put them there).
