hello people I am new to the forum and I am looking for some help..... I want to change all my speakers in my 06 range rover sport s/c I want to do all the door speaker the 2 rear roof speakers and the subs in the trunk door I want to replace with voice speakers,.... now I know there's 1" tweeter 1 3"mid and a 6 1/2 on the door. the rear doors have 2 speakers and the roof 2 also not sure of the size. the subs in the back I believe it has 2 subs. I would like to remove and replace like I said befor with voice speakers..... ok so my question is what would I need to install my after market system and keep the stock radio? also I want to add a iPod adapter.
