excursion vs sensitivty

well im looking at RE audio 8's...and or pioneer 10" pro series... i been in audio for about 20 years now when dr crankinstien was the considered one of the best. but im just used to calling the company and finding out what size box i needed and build out of patical board then and now mdf (mdf wasnt heard of then around my town) for 2 12" i always made the box 5 cu ft with 2 4" ports 12" long that worked for me and all my friends. so now im running 2 kicker comps 10" common chamber @ 2.95 cu ft with 160 rms sealed, i been running that for about 3 years now i been measured @ 132.4 db with them. now im wanting better and louder. i just got my fatmat in yesterday, and now im trying to deceide on my subs, amp (s) , and mids and tweets. since i been a huge fan or us amps and just now found out that they make RE audio then im considering them, but pioneer has been in my favorites list for a very long time... so any help will be considered and appreciated.. and btw budget is small compare to alot of others but its not as small compared to what it use to be

well the generic set up was then thats why im here now, im slowly learning winisd, but im pretty stuck on those 2 brands after alot of consideration im sticking to those 2 for speakers and subs, my trunk lid is the worse thing that rattles the most but i have checked very closly and it seems that my trunk seems to be 2 pieces thats welded in very small places that i cant get behind except in about 12 small slits about 1/2 in by 2 inches, i thought about useing expanding foam but i know i will end up putting to much inthere and causes ripples in the outside skin.
