Well, I bit the bullet, and finally did a full sound system install. I went with a Sony headunit, solely because it had the proper amount of RCAs, and it's backlit red. I think it looks very sharp. I put Infinity Reference series speakers in all 4 corners. Currently, they're just running off the head unit. I got an Alpine Type-E 10" subwoofer, in a sealed box, powered by an MTX amp. All in all, it was about $1100 US. I think it's worth it, to me, it sounds exceptional. I'll have pictures up later. The install went very well, the speakers look stock, and the amp is tucked away nicely, and the box's carpeting is very close to the carpeting in the trunk. If you were to hop in, you'd guess that the head unit was the only upgrade...Until I pop a CD in.
