if im missing something, or dont need one of the above items can someone point them out to me? i appreciate it

 

Are you planning on bypassing the factory amp and running the speakers off the deck itself or do you want to retain use of the factory amp? Reason I ask is because it will dictate what harness you get. If you have no intention to upgrade your interior speakers then you should just keep the factory amp. But if you plan on upgrading them I'd suggest you run them off the deck instead of the factory amp. It will also dictate what harness you get too.

Keep factory amp, use GMOS-04

Run aftermarket speakers off deck, use GMOS-01

Not a good idea to run your factory speakers off your deck unless they are 4 ohm models, most of them are 2 ohm models.

Everything else looks good though

 

i was thinking of replacing the rear speakers with some nice eclipses that i have that could handle things better....front spekaers sound ok....i will be running subs too.

so how would i go about running aftermarket speakers off my deck? do i run new wires from the deck to the speakers??? or is there an easier way?
