Cobalt ss/sc Alternator Question.
How many amps does out alternator put out? Im thinking of putting in my system but I dont want to kill my alternator like I have done in two other cars. And for people who already have a system installed, how many watts are you running and is it dimming your headlights? Thanks guys.

Don't replace your alternator just buy a second one. If you, or if you can get some one to, build you a bracket and rerout your pully system a bit you can get a near never ending supply of power. Your original alternator can just run your factory car stuff. Then daisy chain a few stinger dry cells together charging off of your second alternator to only run your system. Feed those hungery amps the full 14.xx V that they really want!
Yeah that or you can just get yourself a kinetics cap killer....

Alot of shops near me rebuild alternators into High Output units. I might look into this once I figure how many watts the alternator can hold reliably.

I dont think anyone makes aftermarket alternators for these cars yet so you would need to get it form gm which will cost a good bit. The you would have to get it installed. You might as well get it rebuilt into a high output unit if you continue to run alot of juice in your car.

Add a second battery. Get an Optima battery to run the system only, that will eliminate quite alot if not all of the dimming and no worries about all that alternator stuff. Capacitors are nice, but all they do is store the current so that it is more of a constant draw off the battery and when the bass hits it pulls at a not so constant from the capacitor. Supposed to help alot, but not so much. I have a 1,000W D-class amp pushing my 2 Rockford 10's and my lights dim if I turn em up pretty high.

lol no offence becasue your ideas and thinking arent wrong but its funny how you worded it
"Capacitors are nice, but all they do is store the current so that it is more of a constant draw off the battery"
since when do batteries make significant power? yes i know they do make small amounts of power but they mainly store power hence why my cell phone has to be charged often.... the alt makes all the power needed for the car and while 2 batts can be good any battery is just a load on the alt since its just another thing the alt has to deal with

I can see what you're saying, but with adding a second battery the sole purpose of that battery will be to supply power to the stereo and nothing else. Which would keep from draining power being led to other equipment in the car. This is how it was explained to me. I am still new to car stereo..I have a bit more knowledge of car mechanics then electronics.

lol its all good... and like i said i wasnt saying you were wrong it just made me laugh.
anyway yes a 2nd battery is often helpful especially when put close to the amps location (gm already hooked us up there) but since the alt makes all the power i would have to say the final result is alt>battery... now most cars dont need a hight output alt and for most sytems a 2nd battery could be perfect and the price and ease of installation makes for a grea upgrade... but for larger systems adding more batteries is just making it worse if your alt cant keep up in the first place

So then would you think adding a second battery and a capacitor would stop the dimming, without having to even touch the alternator?? I'm sure if you start puttin like 4 subs and 4 amps and whatnot the alternator would have to be replaced but for smaller applications.

I run those exact same amps... and i hate light dimming!
Cap and ungraded alternator for me i guess...
