I have a 2001 nissan pathfinder and it had the premium bose system in it. I
replaced the HU with an alpine 9815 and threw in 2 jl 12w7's but the only
thing I did for the doors is put a PIE converter on so there would not be
any problems with the head uit to factory speakers. Is it worth getting the
factorys replaced. Im used to the highschool days where all i did was cap
off the factorys and use them as tweeters. so if you have any input please
let me know
