I am just building a good system I can enjoy for the music. I think the PA2100s will be fine. 100 watts per corner will give lots of headroom. I looked at the small Kenwoods but I can't see them living in the rear wheel wells packed in foam and dead air. They would have to be wired then stuffed in.
sounddomain.com has the 2100's for $209. Did I get hosed?
Rears:
I plan to gut out the interior to get to it. I have observed the foam block. I see a challange. The car is small and my book almost over speakered. I am sure bass won't be an issue. (I don't listen to rap.)
Don't build a floor in the boot. The cabin air exaust is the grills below the latch through the rear bumper.
