I just finished installing my wrn 3.0 on my 500 and noticed there is no fuse at all on the set up what if for some reason theres a short between the power cable and the battery or anywhere??? I mean If tht battery blows under you I can image that wouldnt be that nice..... But If I was to install a inline fuse what amp fuse should I use, I mean I know you need to pull alot of power for full strength... ??????
