I'm cross-posting my thread from evomn because I know there's a lot of GoPro'ers on here that might benefit from this

So after much screwing around I finally have a microphone setup I'm happy with. I'll save you all the play by play of the trial and error of using a mono mic and trying to set up dual mics. Suffice it to say it was a pain.
On to the good stuff, my materials:
GoPro HD Hero2 with skeleton housing, of course
2 mono mics with inline battery from Radio Shack (I've heard the GoPro mic input is powered, not powered and everything in between. At low volume my non-battery mics sounded fine but I never put them on the car because they suck)
A "Y" splitter with two female stereo inputs to one male stereo out
A mono in to stereo out converter plug ($2.60 at radio shack, yes you need this if you are running mono mics unless you want to fuck around with expensive editing software)
Foam bits torn off a mattress pad. I wrapped these around the mics to cut wind/road noise
Painters tape for securing the mics to the car
And for the results. I made 3 videos each with a different setup. SEE THE VIDEO DESCRIPTION TO SKIP ALL THE DRIVING AROUND. I didn't feel like editing them because they are just test videos so I put times in the description to skip to the WOT pulls etc.
First video is with one mic, this one is taped to the top of the airbox.

Second video also one mic. This one is taped just above the exhaust. It distorts quite a bit, I think it was too close (~10 inches from the tip). Next time I'll move it up a bit.

Last video is my dual mic setup. I used the "Y" splitter to combine the audio from both mics. I was pretty pleased with how it turned out.

Comments, suggestions and criticism all welcome. For me car videos are nothing without good audio. I hope this inspires others to go that extra mile with the GoPro, external mics are worth the trouble!
Feel free to tell me which audio setup you like best.
