You will need know if 6X9 will fit.
5X7 or 6X8 are direct replacements, not 6X9.
For 6X9 you may need an adapter and find out if it will all fit.
There is a jumper for the factory amp, if you need one. Find the amp behind the glove box. You don't see it, you don't have it.
Other than an amp jumper and a head unit jumper, I would use all other factory wiring.
