I just posted this on the general auto forum:

So, Scott and I spent about five hours today installing his new Infinity Basslinks into his KIA Optima. We were initially met with trouble. The first hardship was that we could not get the bottom half of the driver side dashboard unclipped, and thus could not get the rest of the trim pieces out of the way to gain access to the head unit. We then gave up on connecting the subs directly to the head unit. Instead, we decided to splice the wires for the stock rear speakers and connect them to the subs. It was easy enough to connect the wires to the stock harness, although I think this connection may have introduced some line noise to the system. That’s another story, however, and it will be investigated in the coming weeks. To power the amps, we ran a 10 gauge power line from the battery (with a 30A fuse inline), down the front door hinge, through a hole drilled into the door sill, under the carpet to the back of the passenger cabin, and through the crack in the fold down rear seat to the trunk. Connectors were fastened to the power lead and the lead was attached to the driver side amp. Another 10 guage line connects the positive terminals on both amps. We grounded both amps to the screws holding the third brake light. After making all the connections, including two remote bass controls attached under the dashboard, we tried to tune the system. Tuning went just fine, and then we discovered that the above-mentioned line noise seems to get amplified after the stereo and/or the car are turned off. The quick solution for now was to turn down the gain on the amps, reducing the power output of the 10" subs. Maybe next week we’ll be able to figure out how to get the dash off to connect the remote leads on the amps to the head unit. Until then, looks like it’s only slightly louder driving for Scott. btw, someone remind me to change the blog to a dynamic system.
