I installed a autocom super pro avi into my tankbag. I used the $5 RV connectors to get power to the bag, and then a radioshack project box and some 12 volt sockets to make it neat. The hardest part was fitting the helmet, a shoei rf1000. It took alot of work to take apart the helmet, and then carve out spots for the speakers, and place them perfectly. Then you have to fit the front microphone just right to the "loud spot". Overall the installation of the helmet speakers was difficult, and I did not like cracking open the helmet. The system works great, although it took some fiddling to get it right (and installing the backround noise sensor 3 times). The auto volume control is pretty neat but a PITA to get working.

Overall the system is pretty great, and works as advertised. Talking on the cell phone works well, although you have to get the volume control setup properly first. The other signals mix in well, including the auto mute function of the mp3 input. I have not hooked a gps or radar into it but I'm sure they work well too. Overall I think this is a great com solution. I am glad the 6 hours install/fooling around is done though.

Pretty sweet setup. How's the sound quality? I've no need to use the phone while riding but I'd consider speakers if I could get as good a sound quality as my in ear noise reducers.

I have a pair of Shure E3C's that I admit are way better for complete sound quality. However I was actually suprised how good the headset speakers sound when you wear earplugs with them. Its kind of counterintuitive. My ratings would be:

Shure E3C in ear w/foam attachments Sounds great. Very little change from listening at a standstill. Excellent bass and treble. Good noise dampening.
Helmet speakers w/22db ear plugs Lose a bit of the highs/lows but as long as you position the speakers properly the rest comes through pretty nice.
Helmet Speakers. Good but sometimes wind noise comes in from the side of my helmet. Probably varies from helmet to helmet. Mine is a bit noisy (shoei rf1000).

I like the speakers because I only have 1 robust cord that clips right in, and its great for fast on off. For trips over 45 minutes I'd probably run the earbuds. Helmet speakers are great for commuting :)

That looks awesome man! Have you got to use it at highway speeds yet?

I put speakers in my helmet too. I didnt tear the helmet apart to do though.

Check out http://helmetaudio.com/khxc/index.php?app=ccp0&ns=prodshow&ref=AHA1014 for the set up I used incase you have to do it again.
Unfortunately I don't like anything touching my ears, and the Shoei Rf1000 is well known for being a difficult helmet speaker install. Most other helmets are much easier. :) I also have the setup tested to about 95mph indicated, with a 25mph crosswind. Works perfect, and I my test candidates I called could not believe I was on a phone. The advertising was actually telling the truth.

This shows the location of the BGNS microphone.


This is where the cord comes out of the back of the helmet. Duck tape is there to keep out winter drafts.

Speakers installed in the pockets

Microphone mounted in the front of the helmet.


I wired the bag with positive and negative power direct from the battery. I got all my stuff from this page:

I ordered a RV Roof Connector for the pass through on the bag, and a Heavy Duty SAE connector to connect to it from outside the bag. I ran those wires straight to the battery and fused it. Originally I had it connected to a switched power source (fuseblock, but lights would work too). Then I realized in order to keep having a cell phone conversation I had to keep th bike running, even if I had reached my destination. The autocom draws very little power so I just went straight to the battery.
