Sorry to bump up an old thread, but I wanted to thank forbidden for this post. I had been following the install guide by VaBoom (member of Cardomain, Mazda3forums,, etc), but ran into some issues with the speaker wires. He ran a passive component set, and just tapped into the factory wires behind the headunit. Since I'm running an active setup, I was a little stumped as to how I would run the wires.
I do have one question though, if anyone can help. I have the Molex connector pulled out of the door jamb, but I was wondering if there is any special method to disconnecting the two halves. I don't want to just go yanking on things and mess something up. I've already got that blue lever thing swung back, but the thing still isn't coming apart with gentle pressure.

well I got the connector apart. The drivers side cables were just so short, I had a hard time getting the connector at the right angle to let the two pieces slide apart.
To forbidden, one more question. I've got the speaker wires run through the molex connectors now, but I'm having trouble routing the cables into the cabin on the passenger side. How did you manage this? I've shoved every inch of me I can inside the footwell to get a better angle, and fished a snake tool everywhere I can think, but have come up empty. I'll try hitting up the Mazda3Forums for answers too, but I figured you might be able to offer some insight, since you've done this the same exact way on the same car.

This has been insanely helpful! I did the non-drill method but I'm having trouble fitting it back into place. I'm doing this in a 2008 Mazda 3 and using a 16 gauge wire.

Wow...I'll have to keep this in mind next time. I have a Mazda vehicle as well, and I actually went through the painstaking work of fishing my speaker wires through the molex. Took about 15-20 minutes each door. What fun that was. :|

Most pins come out the same way. If you don't have a pin removal tool, it is possible you could cheat it out with a very small screwdriver or X-acto blade.
The side where the male and female pins meet is where you would be accessing the release tab(s) from.
You could always tear them out and drill, but then you would have ruined the factory pins which you may want to re-use sometime.
