So I got a radio from shanghai...and a horn from brazil and installed them this weekend (and last).
The radio is pretty good for the money (see Jerryw's post)...not a Bose system for sure but not terrible...sounds like a top end mono boombox from the late 70's with less bass. And it has a jack to plug in your mp3 player. (heed jerry's warning not to use an mp3 player that has a hard drive...it will crash)
the horn is a Fiamm made in brazil and has a c high tone and a d low...it is the one 88andstillriding liked.
had fun with this...the horn is very loud and i look forward to blasting cagers....ask any questions...i know i could have posted more detail but it is late and i am tired
