Just bought the 2017 Cruze Hatchback last night and i wanted to hook up a couple subs and an amp. What all would be needed to do this? Never hooked up an amp in a newer car like this. My previous vehicle was a 2004 SRX and it had to have a PAC LOC line out converter. Would this require one as well or is there hookups at the back of the touchscreen somewhere that will allow me to hook it straight up. Would doing any of this void my warranty? Should i just go to a licensed/insured installer instead?
