hello everyone im new here to this forum but not to car audio. i recently picked up a 2003 g35 coupe with the pop out nav. but the system is horrible so im upgrading everything. im adding a double din, 4 channel amp all new door and rear speakers, 2 subs and a sub amp. also some little goodies like steering wheel control bluetooth etc.. so my main question is installing it. i bought the bose bypass harness since i will be adding a new 4 channel. i was wondering if i can still use the stock wiring from the bose amp. or if i need to run new wires to all my new speakers? if i can use the stock wires does anyone know the schmatic to tap into em. also for the pop out nav is there anything special i need to do to make sure it works properly? thanks for your help and this forum rocks! i will post pics as soon as i get it started most likley next week.

 

also forgot to mention i have the jdm bezel and the ac control i searched but couldnt find any info any help?

 

Look at the sticky threads. There is one called 2003 Sedan Bose wire colors with diagrams and pics and another called DIY: Add a sub to your Bose equipped G35 Coupe which can point you in the right direction. Also check out the My 2003-04 G35 Double Din Conversion DIY Guide thread.

I used the stock wires to send the audio signal to the front speakers. It's easier to run new wire to the rear speakers when you install them than to fiddle around with the Bose wires.
