Went to install an aftermarket Hu yesterday and everything went well. Installed is jvc kdr 320 w/ lc-gmrc 01 on my 03 tb non Bose/onstar/steering control. It was my first install and I am pretty happy w/ my sound now and my question is why is every time I dim my dome light my Hu lights gets brighter and if I brighten my dl my Hu gets dimmer. Hu is set to auto, any thoughts? it's not a biggie issue,it's just the wife laugh at me lol. Thanks
