Not a clue man. This isnt even a cobalt in the picture. Im not getting mine till hopefully this thursday, if the deal is right. But the system sounds great.. people tell me they are competition grade subs, and i shake the inside of Mcdonalds with them. I've shocked a lot of people with it actually..
the factory deck does not have rca preout. if you want to add subs like i did, you need a line out converter to plug in your subs to the stock system. i can adjust the bass and treb on my subs from the factory deck and then i can also adjust on the amp itself.
I mess with my amp adjustments on my amp. And its neither.. lol. Everyone trying to figure out what kind of vehicle i have and no ones even looking at the subs haha. oh well.. ill tell everyone what it is after i get my cobalt thursday, ok?
