i was wanting to know thoughts on the pioneer avic x930bt head unit? also what size is the door speakers in the titan (front and rears)? i read 6x9 front's and 6.5 rears? what is the BEST speakers to run for vocals? polk, kappa, alpine type r, clarion, boston acoustics? i have 2 10jlw6's in a custom built and ported box, so i have all the bass i want. about to pick up a kicker dx 1000 amp for my subs. now i want clarity and vocals without distortion. the stock speakers in my 2011 have a LOT of distortion. also i have the factor 6disc in dash with bluetooth. i love the bluetooth cause it have excellent noise cancellation, and picks up voice really well. so my question on that is, if i change head units, can i wire the stock mic into the new bluetooth and it work as good or does it have to do with the head unit itself? i have had bluetooth radios in the past and they dont pick up or cancel noise worth a crap. also i want it to have steering wheel control capabilities.
