I used 3 way component hertz in my 00. Amp is a Alpine PDX9 I think it was. Doors are 5.25 inch 6.25 will fit with modification i bought some ebay nokia door boxes and cut them up and mounted 6.25 driver in the doors. The tangs probably not needed with the subs, focal or hertz 5.25 in door would work. The stock amp only sends sub freqs so you really need to change the amp. I am running an active system no rear soeakers and honestly dont need them.

I am running a 996 footwell subbox I moded and drive with the alpine. The alpine has 5 channels.
So my pioneer hu controls cross over duties, and powers tweeter, the dash and doors handle mids crossed using amp crossover to split high mid low mid, the channel 5 sub.

Anyway a decent 5.25 would be easier to install and work.
