It is pretty simple, just time consuming.

Get the headunit...

Connect the yellow wire to a constant power wire (existing constant power or battery)
Connect the red wire to a switch power wire (ignition)
Connect the black wire to the chassis of the vehicle
Connect the White (L)/Gray (R) wires to the front speakers
Connect the Green (L)/Purple (R) wires to the back speakers
Get a window antenna to connect to the headunit for the radio channels.

Time consuming part is running the wires and cutting the location of the products if stock fittings do not exist.

what about running and amp for the speakers ? and do i need to get a higher output battery? lol i dont know nothing about this damn audio stuff

To add an amp to the speakers...

Power wire to the battery
Ground Wire to the chassis of the vehicle
Remote wire to the switch power wire on the headunit (red)
RCA cables to the headunit
Speaker wires to the speakers

If doing this, you can skip the speaker wire step when installing the radio. You will instead run speaker wire from the amp directly to the speaker.

8 Gauge Amp Wiring will be fine for an amp running the speakers. However, if you plan to add a sub amp in the future, you will want to use atleast 4 gauge. This prevents you from having to redo your power wires.

As far as the battery, it depends on what battery you are currently. 9 times out of 10, the stock battery will be fine running a speaker amp. However, if it is an older or low cranking amp battery, it will be best to upgrade not only for the audio system, but the car in general.
