I'm installing a sub/amp combo tapping off the input speakers to Bose amp. Could someone direct me to a guide or schematic of the wiring colors for the speakers. Thanks

BOSE SPEAKER SIZES

COUPE

The tweeters are exactly 5/8" deep and about 1-5/8" in diameter (at the largest point).

You don't have to take the whole door off to get to them to look (you would to disconnect the wires). Just pop off the clips that hold the black plastic panel down.

I also know that Infinity Kappa Perfect 6.1 tweeters fit, as do the tweeters from the MB Quart PCE 216 set.

With the lower door speakers, the stock measurements are: 6-3/8" in dia. with 2.5" of depth.

I think just about any 6.5" speaker will fit, but holes will have to be drilled (Roll up the window first) for any.

The rear side speakers are EXACTLY the same as the lower door speakers. Same part number and everything. Strangely there is no tweeter (or even a cone) on any speaker in the back. See my other thread about possible mounting depths. I made a spacer but there were other great ideas on how to mount better speakers back there.

The 6" X 9" speakers in the rear deck are: 6.5" X 9-3/16" and 3-3/8" deep. Again, I think any 6X9 will fit here.

These are all standard six openings and any install shop can easily do this. If you are doing it yourself, I recommend buying a new 3/16" or 1/8" titanium (for metal drilling, I used Bosch brand from Home Depot, a couple bucks) drill bit. Just drills alot easier through metal in the doors.

As for the screw hole dimensions... just drill. Infiniti uses a weird 3 hole set up for their 6.5" mid ranges that you won't ever match up exactly.

The tweeter will be held down by the stock metal bracket. If your new tweeters are a little loose in the bracket, wrap them in weather stripping or something similar.

The 6" X 9" speakers are standard mounts in the four "corners" of the speaker.

SEDAN

The fronts can fit the same 6 1/2 inch separates as the coupe. I thought the rear door speakers were 6 1/2 also, but they are smaller - perhaps 5 1/4 to 6 - which doesn't really matter because you'll have to make spacers anyway. My sedan has a pair of 6 1/2 coaxials in the door.

The sedans bith the Bose have an 8 inch sub. IMO, don't bother replacing it. Just get a bigger sub in the trunk.

 

Does anyone know if these colors are the same for non-Bose systems?

 

For the non-Bose cars, just get a wiring harness adapter for a Nissan and connect you speakers or LOC from there. The non-Bose system had speaker level outputs, so you'll need an LOC to run the signal to your amp if your amp doesn't accept speaker level inputs.
