[QUOTE="Kickstand, post: 8747253, member: 681842"] So one of the systems I had was in a 2007 Cobalt SS/SC which I bought brand new. The thing came with a 110 amp alt in it This was a major roadblock when building the system. Since the car had only been in production for a couple of years and the supercharged versions on made up 15% of that finding a new alt was a challenge. I contacted every company I possibly could and no one would touch it and I was not willing to do a rewind on it. There was a guy on another forum that had the same car that had a bracket made to add a second alt but it only worked with the stock alts. That's still only 220 amps but still better than nothing So after spending $1500 (Can) on getting a new alt, tensioner, belt and the bracket made and the labour to have it all installed plus adding a Kinetik HC1800 it still wasn't enough to stop my amp from going into protect from voltage drop (Saz 3000D) (2x DD3512) So I added a second HC1800 THis stopped the amp from going into protect but it still wasn't enough to properly run the system. Eventually I had to give up on that setup and go back to my old one which was a DDM2 with 2x DD2512 Still a good system but damn it I wanted more I didn't even really get to break in the 3512's So sometimes big alts are not the answer or just not possible This was all in like 2008/2009 If Lithium and super caps were around or maybe they were around but they were not out there to easily get. It would have probably solved my problem. [/QUOTE]
