[QUOTE="Fakecodename47, post: 7271839, member: 631427"] Its going in a 2008 cobalt ss I have stock battery and extra battery in the trunk. I dont have any information on the battery. Is there any way I can get the info I would need using a multimeter or would i have to get the model of the battery? I will be upgrading to 0 gauge stinger wire and doing the big 3 before putting in this system. Do I have to upgrade my alternator? I listen to rap and rock but only care about the subs with the rap so I will be using a ported box. Daily use, volume at 15/40 most of the time, volume at 30/40 when blasting which is usually about 3 mins once every couple days when someone wants to see how loud they are. [/QUOTE]
