How long of an interconnect cable do I need?

[rsmeanie]

I'm planning to install a couple amps in the trunk and need to run a set of 4-channel interconnects from the dash to the trunk. What length interconnect do I need? 3, 4 or 5 meters? I plan to run it alongside the tranny hump down the center of the car and under the backseat.

4 meters should do it since you are going right down the center of the car... that cable would be just over 13 feet...

5m would be to long...
