After seeing Savage's guide to installing a BassLink II sub (nice guide btw, was very helpful), I decided to splurge on the BassLink I. I've got an Alpine 9857 driving the thing, and used a SCOSCHE 8 guage wiring kit (around 60 bucks) to "get er' done". My method was a bit different. I ran my wires on the sides of the car under the removable panels. The signal and power cables were run on opposite sides to avoid interference, and only meet at the end. I drilled holes on the seat frame to mount the gain control remote, and capped the sharp ends of the screws with wire twist-caps (ingenious improv idea on my part i think, hah). Anyways, here's some pics of my install.
In-Line 20A fuse mounted to top of fuse box, lined up the screw holes on the very right notch, just between two big fuse blocks
Power Cable (8-guage) runs through firewall via drilled hole about 1/2 inch left of the gas pedal cable
Power, REM-cable, and remote control cable run under the panels and emerge neatly behind the back left seat
Sub is nice and small in the back, but still hits hard, but smooth (i dont listen to rap)
I drilled holes and mounted the gain-control remote onto the driver's site seat frame. It's a slightly far reach, but nothing uncomfortable.

UPDATE: So, I listen to rock music, and almost never rap unless I'm out barhopping and partying. Anyways, I decided to give "My Humps" by the Black Eyed Peas a shot, and WOW is all I can say. The bass was pounding like crazy, and it sounded awesome.
