[Fifty-Three]

my suggestion is

if you don't know what your doing....take it to somebody that does.

 

[Fifty-Three]

parts are:
dash kit
antenna adapter
harness to retain chimes and rap
6 3/4 component speakers (with tweeters) or oversized 6 1/2s
4x6 speakers

well, just check out what forklift said...

Also, The harness that he mentioned is really expensive but it does retain the factory chimes...

I used a simple truck harness on my install because its 10k times cheaper and it gets rid of the chimes......

Look on ebay for a dash kit, and adapter you can usually find these bundled together....one is just as good as another.

speakers are up to you.

Also on a crew cab I would suggest jack relocation, removing some of that plastic and such, and using a behind the seat set up.....only because seats in a crew cab are different from an extended cab and under box seats are a beeyotch in a crew cab
