This might sound like a dumb question but I just want to make sure. I'm putting 2 l7 in a 06 prius. The battery is in the back. I was wonder does the distance of the power and negative cable matter? Also distqnce for the fuse as well? When I first did research i think i read somewhere that said something about 3 feet from the fuse block or something. I had the l7 in my rsx with no problem now im putting it in my prius. Also keeping the factory deck so im using a hi low converter. Thanks in advance y'all
