i just bought 2 rockford fosgate amp, those are 401S and 601S, and 2 12" MTX subwoofer, but the things i got stuck here is i cant install it
(some guy told me that at the good guys)cuz he said that the bmw business CD car radio doesnt have the "pre-out" at the back of the car radio?which mean i cant connect the amp to the head unit, did he said it rite?
i had a 99" 328i
does the 99" 328i head unit really doesnt have the "pre-out" at the back of the head unit?if it dont, i have to change a aftermaket car radio?(that would be ulgy look)
