i just got done putting in four new 6.5 in my car that originally came with the bose system and to my surprise it was only a three speaker system, what a scam. well now my new on e soudns bad *** and it wasn't that hard to run all new wiriing for the four speakers. all in all it was a 5 and a half hour job.

 

that took a while to rewire, but I had to do the same and took a while too. With the Bose system, I think those were 2ohm speakers so you are running them at 4 ohms now

 

yeah i thought it was a one ohm system, oh well i am at four now and it sounds way better than that three speakers system
