Does the 7 speaker infinity system have a hook up for a sub woofer?

 

anybody?

please, I'd rather not install only to find out i get feedback upon turning off engine

 

k amp installed using a converter

 

The only time you can add a sub directly to a factory system is if it had a sub in the first place...and then you still have to be careful, because most factory subs are higher impedance than aftermarket subs. And if you go putting a 4 ohm sub on and 8 ohm stable amp it will more than likely eventually burn up or go into protect mode alot.
