i personally have a solid jbl system im my 95 se
the 5 1/4 compoents in the front were no problem the tweeter mount was already in the door and the mounting plate just had to be turned backwars and it fit fine...
the 5 1/4's in the back just drill 2 new holes and drop 'em in
the only bitch was the head unit (kenwood excelon) and the fact that you need a dash mount kit... theres a nice size blood stain now under my center consol...
all you need is time...
