20 ft seems long for our accord. hell, I've got 6 fters that reach from the HU down along the center console to the back seat floor mat area. i'm sure you could run an additional 6 fter up under the back seat cushion to the amps in the trunk if they are to be mounted closer to the cabin. but if you're mounting them further back toward the headlight, perhaps a 15fter will do. I can't see the need for 20ft though. Aren't those 17 - 20 fters reserved for trucks
