Searched the forum for an answer but couldn't find one, sorry if this been asked before. Trying to find out about how much power cable will I need to install the amp on my 2015 RGS. I know the amp kits come with extra long cables, but I'm buying it by the feet. Running the 12V, fused 8 gauge cable from the faring, under the tank, to the battery. I guesstimated 4.5 feet long, does that sounds about right? As recommended by Rockford, I'm running the same path for my ground cable too. Thanks in advance.
