Im in the middle of installing MB Quart speakers I bought from Crutchfield for my front doors, The trouble I am having is for the tweeter components, I dont know which wire is + and which is - positive / negative , To wire them... The toyota harness on it has Light Blue and Light Green colors. Anyone know this? Thanks in advance!

 

Found the answer after searching the forums for 20 minutes.
Left Speaker:
Purple = - Negative
Pink = + Positve
Right Speaker:
Light Blue = - Negative
Light Green = + Positive

Hope this helps someone one day.
Thanks!

 

You're still using the passive network that's included with the MBQuart set, right? If so, I'm not sure why you're interested in the wire codes.

You should (ideally) drive these components from an after-market amplifier, and run new, larger wires into the doors. You can install the crossover in the door, or in the cabin, but it must go between the amplifier and both the mid and tweeter. If you mount the crossover in the door, you only have a single run of new speaker wires. If you're not using an after market amplifier, you can make the wires that originally connected to the 6.5" to the INPUT of the passive network. The output of the passive crossover will go to the respective speakers, 6.5" and tweeter. Again, there should be no reason to use the tweeter wires.

 

Well I will run through it again tommorow because I finished the passanger door, And comparing it to the factory components in the drivers side door these MB Quarts sound very dead, Their very quite compared to the stock Pioneers. I did mount the crossovers in the door, No amp is powering these yet, Its a Pioneer AVIC-D3, Its ran to a Eclipse XA1000 Amp and then to an MB Quart 10" Sub which does a great job by the way. And then these, well I was planning on calling crutchfield in the morning and sending them back for the polk momo's, I'll stop by my friends place tommorow, he's been helping me with all this, we'll double check and see if its an error on our end. Thanks for the heads up.
