Hey guys so unfortunately some ************* broke into my car yesterday when my Yukon was parked at my work!!! They stole my pioneer double din navi unit and my iPod which was Hooke up to it. Considering this happened I am not sketched out to drop another 8-900$ for a new double din. Was curious to know if it is possible to have my amp and subs hooked up to my factory head unit, and of so how different is the sound quality? Please help me out!!
