It's the 165A1 kit, so I guess that's kevlar. I wanted something that sounds nice, but since we're talking about a Sunny, there's so much noise that I'm not going to spend silly money on a stereo.
I did measure the depth beforehand, and the car had 6.5" speakers installed when I got it - some obscure italian job. Upon googling, I found a couple of polish and finnish hits. Promising.
But - the screwholes where the 6.5" speakers had been didn't align with the focals, and it looked like a lot of hassle. But my local ICE shop wanted about £130 for the job. So I went back to the garage, got sick of the idea, and just drilled new holes where I needed them. So they're in now (look in my project thread), and the sound great. I'm considering a tiny sub to keep under the seat though.
Currently I'm just using my Alpine headunit, and it's clear that the speakers are heavier to drive than the old ones. But I'm not sure if I'm going to go for an amp as well.
The crossovers went in nicely under the doorcards as well, so I'm happy. ^^
