I've done a lot of searching through the threads and thus far only heard of the focal 165k2p's as fitting the factory door speaker locations w/o any customization, i.e. spacer fabrication/install. Those speakers sound amazing, but are definitely out of my budget. Since I don't know anything about fabricating speaker brackets, what other speakers will fit into this spot without any extra modding? Does anyone know dimensions I can fall under to make this speaker install easy for me and anyone else trying to do this for the first time? Thanks.
