[nali02]

white lightening, i opted to add sirius satellite radio to my denali with my already installed alpine iva-d300 indash tv, all i had to do was install the sirius expansion box and antenna (its magnetic and sleek and mounts on the roof above the rear cargo area) and my alpine automatically detects it being there as it is an option in my "sources" menu. my question is however is that i noticed the signal being pretty weak at times, mostly when i come across a hip hop song with good low end frequency or "bass" that was pretty weak (keep in mind i have 2 12's, so i can tell a lack of bass pretty easily), would this be because it isnt factory installed?

i probably didnt make any sense to you with that so let me know if you understand what im asking.
