Questions/Opinions Needed

I have a 1995 ford mustang and am going to be redoing all of my interior. i have plans on taking the dash out, door panels, and the back pieces around the back seat These pieces consist of plastic and vinel pieces. for the dash i plan on just adding a spot to put a 7 inch or so tv screen, 2 or 3 gauges, and 2 tweeters. as for the doors i plan on adding a 6'9 or so speaker in each door panel.  and as for the back i would just put add 2-4 6'9's.

For this project how should i go about it and where should i start off?

My other project it to build a custom system in my trunk. Right now i have 2 12' kicker comp subs and a kicker amp. i don't know which direction to with that, so any ideas would help out alot. i'm thinking of doing it the way that the man that was doing the mazda miata did it.  also on the top of the trunk i was thinking of putting a 10-14 inch tv screen with 2 tweeters

Any suggestions would help

it is my only car, but i usaully get rides from my girl friend and everyone else. i go to shows alot. i'm debating if i should do the work or get someone else to do it. how much do u think it would cost for someone else to do it including everything?  also which way should i go?

dont do 6x9's at all. your car has 5x7's (6x8's as ford calls em). put a good set of 6.5's in the doors as your front stage is the most important. it is simple to do, cut a peice of 1/4" hardboard the same shape as the 5x7 so it will fit the stock location using the factory screws. then cut the 6.5" mounting hole in the center of it, carpet the adaptor with black carpet. then use a decent 5x7 in the rear for rear fill (not as important). dont get suckered into buying the 6x9's just cause the wattage stamped on the box is a bigger number than any other speaker, most good speakers are geared to handle around 75 watts rms. (a factory hu puts out approx 3-5 watts rms and aftermarket units around 10-15 watts rms.)

alright thanx
