is there a definitive list of what the speaker sizes are in the g37 sedan? nobody seems to know and crutchfield is not on their game when it comes to the G37 ...

 

anyone have a detailed lay out of the g37 sedan wiring? Or even better, what wire colors are needed for Right Rear +/- and Left rear +/-. Also what wire to tap for amp REMOTE? *Sorry if this is covered elsewhere..I'm at this thread

 

Good Info

 

if i want to use the front and rear outputs from the radio before the amp, i connect my amp to these pins on connector B41 / B42, correct?

(23) Rear Left - (SB)(Sky Blue) **Preamp from HU
(24) Rear Left + (V)(Violet) **Preamp from HU

(25) Rear Right - (Y)(Yellow) **Preamp from HU
(26) Rear Right + (BR)(Brown) **Preamp from HU

(33) Front Right + (R)(Red) **Preamp from HU
(34) Front Right - (G)(Green) **Preamp from HU

(35) Front Left + (P)(Pink) **Preamp from HU
(36) Front Left - (L)(Blue) **Preamp from HU

in other words, there is a balanced (+ and-) coming from the headunit / nav unit that exits at the connector to the amplifier at the above pins, right?

then, if i want to use the stock wiring to connect the outputs from my new amp to the factory speaker harness, i use these:?

(1) Front Left Mid/Tweeter + (L)(Blue)
(2) Front Left Mid/Tweeter - (W)(White)

(3) Front Right Mid/Tweeter - (LG)(Light Green)
(4) Front Right Mid/Tweeter + (V)(Violet)

(5) Front Right Woofer + (G)(Green)
(6) Front Right Woofer - (R)(Red)

(9) Front Left Woofer - (W)(White)
(14) Front Left Woofer + (B)(Black)

(18) Rear Left Mid + (L)(Blue)
(19) Rear Left Mid - (P)(Pink)

(29) Center + (L)(Blue)
(30) Center - (O)(Orange)

(31) Rear Right Mid + (LG)(Light Green)
(32) Rear Right Mid - (Y)(Yellow)

is that correct?

thanks much! i am setting up a rather high powered and advanced system using the factory locations (other than the sub, as i will be using 2 12" subs in a small box) and a JBl MS-8 processor. i do not want to cut any wires and want to keep the install as stealth and reversible as possible ...

p.s.
which is the remote turn on lead? this

(10) Power/Key (Y)(Yellow)

or this

(20) Power/Amp On (W)(White)
thanks again!!! pics and log to come!!

 

Where are the BOSE amps located?

 

In the trunk

 

In the sedan the rear speaker is 11". You can use a 10" without too much trouble bit a 12" would require some cutting. That would be LOTS of work.

 

Ok I did try to search but found nothing. What's the power rating of the 11 speaker system? What's the power rating of each amp?

 

what is the b41, b42, and b43 meanings?

thanks

Has any body answered this.....I am looking for the power capacity (in amps) of the power wire to these stock amps (bose amp or Woofer amp), is there a dedicated fuse for each??

 

I'm trying to find the passenger side wires for the Right Front woofer in the passenger side kick panel and I am having no luck. These wires (output from the bose amp, are Green (+) and Red (-). I see the Driver side woofer wires Black(+) and White (-), in the driver side kick, but I also see Red and Green in that same bundle on the driver's side. Does anyone know if these wires travel under the dash, all the way across to the passenger side Molex?

 

thanks for the information!

 

Are there any crossovers in the doors or rear. My question is, if I change my front and rear speakers, will I have any issues using the factory wiring?


Thanks

Tom

 

If you are running a serious aftermarket amp set up, you will need to run higher gauge power distribution.
