Infinity G37 Sedan with Bose. Need Help
Hi, I know it is not a Vet, but my wife just purchased a 2011 G37. A nice little car, not my taste, but she gets what she wants. lol
Well the car has a Bose system very similar to my Vet so I want to upgrade it for her with and amp, some dore speakers and maybe a small sub. But the configuration of the head unit will make it very hard to replace so I want to keep it untill someone comes out with a kit to replace it.
I have located the bose amp in the trunk and was wondering how I am supposed to know which wires to cut into for the preamp outputs. I am not afraid to soldier in some RCAs but I have no way to know witch wires to cut in.
I cant find a service manual, and I also dont even know what size speakers are in the doors for sure?
Any help would be greatly apreciated.
Sincerly,
Lionel C

speaker size depth
Front 1 8 3
Front 2 2 1.5
Front Tweeters 1 1
Center 1 3 2
Rear 1 3 2
Subwoofer 1 6X9 3
Subwoofer 2 6X9 3
Personally i would do 6.5 components of your liking a 2 way or a 3 way could be made to work.
As far as a diagram i bet its floating around on a forum somewhere. Otherwise this is what I would do. Pull the fuse for the bose amp so it wont turn on. Turn stereo on, you should have no sound. Turn volume about half way up. Burn a 60hz test tone on a cd and play it. Now take a multimeter on AC volts and probe the different pairs of speaker wire (each channel should be a twisted pair). When you get a reading on meter have someone very volume it shoudl correspont, I would expect max to be somewhere between 2 and 5volts ac. So dont set your meter on the 100 volt scale. Then very the fader/balance to isolate which channel is which. Now turn radio off, etc, and you are done

Here's a good link to one of Bing's installs on a 37 sedan:

Yes, it is way more than you are looking at getting into... but great info.

Anyone have any ideas how I can deal with this without spending a ton of cash?

Differential balanced inputs at the Bose amp in, patented junk signal at the Bose amp out to compensate for the dime store speakers, therefore the best way to avoid noise issues is to use your Jl amps (which, depending on the model, will have them). Hopefully you can get by with the remote bass control **** and x-ver adjustments on the amp(s). If you have some tweaking that needs to be done for it to meet your satisfaction that is beyond that and whatever features are on your passive cross-over adjustments for your chosen component set(s)... then you need either a new deck with adjustable parametric or just go for an JBL MS8.
Seeing that it is your wife's car...the last thing you want is for it to be a never ending project with "just one more thing to do"... because you will never hear the end of it, right? The honey-do list is not a thing to mess around with
IMHO I'd say peace of mind is worth the extra 8 bills on the MS8.
