Just had a kicker amp and sub installed (the one that goes behind the rear seat in the stock position , truck is an 2016 xlt screw) and after about a 30 minute drive I wanted to take a peek at it , touched the amp and noted it was piping hot to the point you couldn't leave your hand on it . Is this normal ? The dealership installed it and as they aren't audio experts per say was just wondering if they could of wired something wrong . Everything seems to work though just a little concerned ! Thanks for anyone with any advice . Cheers!
