i want to install a kicker 10" 350 watt sub with a dual 300 watt amp i had it in my previous car but now i have a 2005 cobalt ls coupe. it has the stock cd player with a 6 disc changer, but what i want to know is can i install the sub in the stock cd player? and if so will it void the warranty? please i am open to all who read this

 

well with the dual amp it should have can with wire to splice right from the speaker wire(probably long gone now) but thats one way to do it with the stock equipment

 

yep....like budsjlm said....use a line level converter(only about $15) and hook it up to the rear speaker leads. That will provide you with and RCA input to the amp
