bout to replace everything factory in lil sis's 95 3.4L bird. how can i tell if it has the monsoon system or not? (no signs on tape deck). also what are the exact sizes for the 10 speaker system? i didnt get much help using the search ... i'm guessing the door is 6 3/4 components, mid is 6 3/4, & rear is 4" with 2" tweeter enclosure? am i close? can that be cut to fit 6x9's fairly easily? also if it is a monsoon system i'll need to add an amp to get at 4 ohm for the speakers correct? if it's not a monsoon is it 2 or 4ohm?

lastly just a question on preference if yall dont mind ... what are capable speakers on a budget? i personally like RF & their prices are gettin perty low, but i've yet to use anything but subs from them and i blow out pioneers too quick.

thanks
kris
