Rosen Navigation, Amplifer Instsall, Subwoofer Install

My wife and I bought a 2014 Mustang Convertible Roush stage 1 about a month ago. The care is awesome, but the stock stereo sucks. Even the shaker units I have heard leave alot to be desired. So we immediately looked into upgrading the stereo with Nav, amps and a subwoofer.

The first thing I installed was the Rosen Navigation unit. We were very happy with the quality and the seamless integration with the factory sync system. We now have a great navigation system, backup camera, all the sync functions, and a touch screen. All the steering wheel controls and bluetooth still function the same if not even better since everything is displayed on a 7" screen. The install of the stereo itself was easy, the hard part was running the cable for the backup camera and the antenna for the gps. For the GPS I chose to run the antenna along the and over to the rear view mirror. The antenna routes along the inside of the factory wiring for the auto diming mirror. The base unit is adhered to the backside of the rear view mirror with double sided tape. This position gives the best gps reception and is not seen from in the cab. Even when looking at the rear view mirror from outside of the vehicle its hard to even notice the antenna since the back of the rear view mirror is black plastic just like the antenna base.

After the Nav unit was installed, it was time to focus on making the stereo itself sound better. We decided to start with two amps, and 12" sub, the zen enclosure box.

I installed the two amps on the left side of the trunk, and the sub on the right side of the trunk. I made a custom mount for the amp fuses, and I figured out a way to route the new speaker wire through the door Molex connectors. The 12V remote turn on was tapped from the power to the antenna located in the trunk, and I used a Rockford Fosgate 4 channel hi to low converter to run the RCA cables from the head unit to the amps. When installing the hi/low converter it is necessary to make sure to use the correct wires when your system has the sync option. The left front speaker routes to the sync system first then outputs to the speaker. All the other speakers are easy to figure out by using these two diagrams and pinouts that I found on the net. I installed the remote gain control for the sub amp in the center console. Easy to access but hidden away from view.

I am sure I am missing a bunch of info, if you would like to know something specific then let me know.

Amp 2- rockford fosgate R400-4d
Speaker - Rockford fosgate P2D2--12" punch @ 2ohm

Very nice! I'm sure the sound quality is leaps and bounds better than the factory setup.

I'm definitely digging the way you got those amps mounted! Fancy!


I'm not a "tuner", I am a ecu software engineer. Its different.

2011 GT500 = It gets me from A to B

If you want good technical help. Put your Year, trim, engine, and PCM code in your post! Its easier that way
