Oarhe O's 2003 Infiniti G35

Custom dash with aftermarket stereo

Installation Description

First, I removed the trim pieces under the steering wheel and under the passenger-side dashboard. Then I removed the clock trim and the trim below the shift knob, after removing the shift knob. If it's a 5-speed AT, put the car in neutral, remove the lower portion of the shift knob and remove the retaining pin. If it’s a 6-speed MT, unscrew the shift knob from the shifter boot.

After I got the trim pieces out of my way, I installed my double-din head unit and the A/C controller board in my new trim piece. Then I had to remove my navigation unit from my old center console trim piece and install it on my new trim piece. Once it was installed, I set every everything in place and connected all available harnesses.

Editor's note: Oarhe's dash is a custom installation job. The Metra integration kit does not normally allow you to keep the factory navigation screen, but Oarhe found a way to make it work.

The two that remained unplugged were my steering wheel volume control and my navi voice and mute lines. To fix the mute line I had to wire the gps to the TIP31 transistor and then the transistor to the mute line, wire the gps audio out +/- lines to a line out adapter, then to the amp through the high-end input.

Then I ran RCA cables from my head unit to my JBL GTO 14001 and my Kenwood KAC-8405 amps. I ran a 4AWG power line from my battery to a distribution block in my trunk. the 4AWG line has both a 150A circut breaker and a 160A fuse within a foot of the battery. my JBL has a 4AWG line coming from the distribution block to it and my Kenwood has a 60A fused 10AWG line coming from the distribution block to it.

I am using 10AWG speaker wire from my JBL to my Alpine 1043d and 12AWG speaker wire from my Kenwood to my Bose component speakers and 10AWG from my Kenwood to my rear Bose 6X9's. To finish this process, I replaced my trim pieces and replaced my shift knob.

Q&A Section

Why did you decide to upgrade your A/V system?

The G35 has a cheap circut board that is shared between the HVAC and the stereo, mine went out and I lost control of my stereo and heat/AC. My car was constantly blasting 90 degress and I had no audio.

What's the first thing you show people about your installation?

My head unit and my subwoofer.

Why did you choose these products?

I chose these products for compatibility, quality and to achieve the sound I wanted.

What was the most difficult part of the installation?

Removing the clock trim.

What plans, if any, do you have for future upgrades?

I plan to replace my component speakers and 6x9's.

    What if you're not using the factory amp for the Bose ? Can you replace those 6x9 subs for regular 6x9's ?

    Is there any install kits on the market or specialized head units that keep the factory Navi in my 2004 G35 sedan?

    John, Not at the moment, at least not in our inventory. A custom solution like OarheO's is still the best way to go.

    Charday, if you replace your factory head unit, you'll lose your factory navigation. So, you'd want to explore aftermarket head units with navigation.

    Can you provide me instructions on how you keep factory navigation and aftermarket double din. Thanks
