You need to get the lines from the trunk to under the car. Talk to Gerald (Snake Bitten) - I believe he just drilled a hole and put a grommet in. Then just slit the carpet and you're good. It's something that, if installed cleanly, can be removed without it ever being known it was there. Depending how adventurous you are, you could do what I did and run the lines out through the opening in the body where the factory wires for the amplifier go - but that was a GTS, although the RT also must have some method of getting the wires from the amp to the head unit - so there's an opening somewhere in there /images/graemlins/smile.gif
