Re: Upgraded the Door Speakers in my Leaf

I elected to disconnect the factory tweeters after all as they add this high frequency "scraping" to the sound. Depending on how much high frequency hearing loss you have, you might not notice. It definitely sounds better! A long term listening test will confirm... :)


Which brand and model coaxial speakers did you install? I can't decide if I should try to replace the tweeters in the A pillar or just disconnect them and go with coaxials like you did.

Re: Upgrading Speakers in my Leaf: Phase 1

By the way, the Nissan Service Manual wiring color chart is incorrect for the Leaf.

Here are the colors I found:

Front Left (+) Blue / Grey
Front Left (-) Violet

Front Right (+) Red / Grey
Front Right (-) Brown / Grey

Randy,

Are you sure about that?
If we assume that the original speakers are all made the same, then that wiring combination would put them out of phase based upon the wire locations on the plugs.
Could you double check against your photos?

Agreed - from what I found the blue/grey and brown/grey were the negatives on the front...

Also, the polks definitely fit fine, and sound great - but the adapters that come with them suck. There's PLENTY of room in the door for the external crossovers. It's a bit more work, but it's well worth it for the increased crossover quality as compared to other coaxes. The adapters, though - they have three-bolt mounting points *almost* in the right spots for the leaf, but not quite - so if you force them in, they don't seal up against the door well. So, if you want to use the polks, get a set of nissan speaker adapters as well. I think these are the right size: http://www.amazon.com/Metra-82-7500-Spe ... B0015G17VE (personally I just made MDF baffles; I was doing it for the front anyway since the front as an oversized 6-1/2" midbass)

Did you disable the tweeters in the A pillar?

I haven't yet; I'll be making pods in that area anyway, so I'm keeping them working until I get the pods made to put my own tweeters in. So probably several weeks... :/

How do the speakers sound with the tweeters still there? Don't the tweeters still draw power from the head unit?

Fine- I've gone through the wiring and there's no crossover, the speakers & tweeters are just wired in parallel (though there's likely a capacitor crossover built into the tweeter). Also, the front and rear door speakers are identical.

So, my configuration right now is a midbass from a 3-way set running as full range in place of the front speaker, wired by the factory in parallel with the factory tweeter.

Obviously not an optimal configuration, but there's no way I can do all the work I want to do at once, so I'm trying to find ways to do little bits here and there while keeping the system at least minimally functional - And a midbass wired in parallel with a factory tweeter sounds a lot better than just a midbass :)

SPEAKER WIRING UPDATE & EASY BAZOOKA WIRING:

SPEAKER WIRING UPDATE:
The discrepancy between observed colors at speakers and colors on wiring diagram, and for that matter wires coming out of head unit, is because Nissan, in an inexplicable act of obfuscation, actually changes the wire colors between the head unit and the speaker :roll: . If you study the wiring diagrams in sufficient detail, what you learn is that the colors and destinations shown for connector # M83 as shown on page AV-183 of the shop manual are indeed correct. For the purpose of hooking up a Bazooka at the head unit (which I just finished this afternoon) you can not follow the speaker colors at the doors.

For the Left Front Speaker output, postive is pin 2 and a blue wire at the head unit, but it changes to a purple wire at a harness plug ( M11 to D22 ) where it uses pins 1 and 2, but they have different colors in the two halves of the harness. The negative signal for that speaker begins at pin 3 on the head unit in a pink wire. It then becomes a blue wire at the same M11/D22 harness plug. So, Blue and Pink becomes Purple and Blue, with the Blue now on the opposite leg from where it started :? .

For the Right Front Speaker output, postive is pin 11 and a green wire at the head unit, but it changes to a red wire (no kidding :o ) at a harness plug ( M10 to D2 ) where it uses pins 1 and 2, but they once again have different colors in the two halves of the harness. The negative signal for that speaker begins at pin 12 on the head unit in a red wire. It then becomes a brown wire at the same M10/D2 harness plug. On the right side, Green and Red at the head unit become Red and Brown at the door, again, the Red wire is now on the opposite leg from where it started.


EASY BAZOOKA WIRING:
If you use a Bazooka extension harness "FAST-BTAH" and then the Bazooka "FAST-9999 fast-universal harness at the head unit, it all goes together very simply. The single harness runs down one side of the car and has power, switched power and input wiring. I guess Bazooka is not concerned about noise transmission, and I can not detect any unwanted noise in the finished installation ( of course, the Leaf does not have the usual three causes of noise in the sound system: ignition, generator or alternator)

The extension harness plugs into the Bazooka. All you have to do at the back end of the car is attach a ground under the back seat. At the front, the harness plugs directly to the "FAST-9999" universal harness. The universal harness is very nice. Each lead has a positive screw-on wire tap connector, and each lead is labeled as to what it should connect to. Everything you need to attach is right at the #M83 plug on the back of the heat unit, even switched power ( pin #7 blue wire) and a heavier guage hot lead ( pin #19, heavier brown wire)

The whole installation went smoothly and the system works beautifully. I did some experimenting with location and direction of the Bazooka and discovered that the manufacturers suggested location, in the right rear corner pointed at the hatch 4 inches away, sounds way better than strapped to the back of the seat or several other positions I tried. Guess they know what they are doing ;)

I am enjoying the sound very much with 4 of the CDTAudio Speakers and the Bazooka. I am still thinking about new pillar tweeters though, with only midrange in the front doors.

Re: Door Speakers & Subwoofers in my Leaf

My Leaf arrives in a month and would like to order some speakers for it. It looks like two people on this thread ordered aftermarket speakers. Will any 6.5" speakers fit? I'm totally lost when you guys start talking in your audiophile lingo- can someone recommend a speaker to use if I don't plan on adding subs or disabling the tweeters if it turns out to be difficult? Thanks.

Can someone translate this for me? What are external crossovers, should I get them, why are they more work and what are coaxes? Thanks.
