Ok, I feel as if this is in the wrong section, (but its mainly for my sound system so I mine as well ask here)...so here's the deal

Does anyone know where I can find a H/O Alternator for my 2007 Cobalt LS?

 

Bump....
Is this good?

That is going to be your only option...how much rms are you running?

 

I will be running around 1500 Watts, the reason I'm really lookin into it is b/c my lights still dim even with a better battery (kinetic HC1800), right now I'm only running 1,000-1,100
(2 alpine Type R 12" and 2 alpine mrp-500's to power them) and idk if my alt will be able to charge all three amps, third being mrp-f300 50wx4 @4ohms (yet to install). Thoughts??

 

I had 2400rms on 2 yellow tops with stock alt and big 3 done...if you want lights to stop dimming at all then get a new alt or look into HID headlights because they do not dim

 

i think you will have to do the big 3 upgrade and you will be fine.

 

^^^that's what I was going to say..it's still going to dim a little cause your going to have voltage drops with 1500rms

 

Which HID'S do you recommend? Website etc, and thanks its good to know that I don't have to upgrade my alt

What all do I need for the big 3?

 

hope this helps
