You cant mess up anything. The door has I think just one screw, the rest of the door you just pop out and lift up. The speaker has 4 screws and two wires. I don't see how you can screw that up. It's not rocket science. If it is the factory speakers you are replacing you will need to cut the cables and replace them to the female connectors that should be included with the new speakers, which you should be able to do, and then its just put everything back together. As long as you have a little common sense, its something you can easily do.

 

I installed 6.5 inch 3 ways into my '94 Accord myself. The hardes part of removing the door panel is the door release itself. The rest is simplistic. The reccessed screw in the door pull is indeed the only screw that actually holds the door on the rest of the panel is held by the standard push into the door type plastic pieces (whatever they are called it escapes me at the moment.) The door release is the only issue being that it must be carefully removed but it is not a huge issue in and of itself.
As far as the deeper then the door can handle speakers there is plenty of room on the door paneyou will need to replace them if you want a better systl foor them so if you make mounts (A drill a jigsaw, some plywood and pressboard, gule and lastly clamps and you can make your own mounts easily.)

The stock stereo sounds a whole lot better when you just change out the speakers and you have to replace them if you want to upgrade the stock stereo system anyway.

 

go buy a book:dunno:

 

my boy helped me do this today and we just broke the same grill off and used some "industrial adhesive" to glue the grill back on, since it's not like im ever gonna change the speakers again. if i wasn't there to see him work on for me, i wouldn't know the grill was snapped broke off.

 

I'm 15 and I installed speakers, decks, amps and wiring in both my parents cars, it's not that hard. Don't waste money taking anything to a installer. One was a 94 Accord

 

You installed amps in your parents cars?

 

lol, Yup 4 Way for the speakers in my moms 01 Tacoma and a 400watt mono in my Dad's 94 Accord for a Alpine Sub
