Rincon 650.... from what Josh at Audio Tubes tells me, is that the speakers aren't marine, but regular speakers and they perform great when wet. He just sprays alittle WD40 on them before and after he rides and it keeps the voice coils from rusting and the cones from drying up. Iam not sure about running a dual outlet off the headlight pod, buy one and let us know.LOL
As for the volume on the iTunes....basically all you have to do is right click on the song of your choice, then click on get info, then options, there you will see a slider bar ( I typically slide mine up to about 80%). This will give you the volume adjustment. Granted you have to do it to all of your tunes. But, I have done it to all 3000 songs that I have on my iPod.
If you need to do it to all of your songs, all you have to do is highlight one song, then click on EDIT in the upper left hand side of iTunes and choose SELECT ALL, then go back to your songs and right click on them then do the same as before, get info, options, and then slide the volume control. It will ask if you want to modify all that music and click yes. if you have a ton of tunes like I do, it will take awhile for it to adjust them all.
Then hook up your iPod and sync it...all of your tunes should play much louder. Keep in mind though that some songs are recorded at higher volume and they might be distorted, if they are just go to that song and move the slider bar down unitl it is no longer distorted. I hope I haven't confused you guys...good luck!!
