Hi, I have been having an ongoing issue with dimming lights in my 2007 cobalt LS. I have done the big three in all RF 1/0. Have a 275HO alt from DC power. I have recently added a 10 farad RF Hybrid cap that helped a little. For batteries I have 2 kinetiks. an HC1200 for starter battery and a HC1800 for extra capacity. The stereo consists of a RF T2001BD wired to 2 ohm, a T-600-4 for the Mids and highs. I was thinking I should move the factory ground point in the trunk to something better. ive cleaned off the metal good in the stock location and have a RF ring terminal attached to the end of the ground wire. I need some sugggestions. Maybe larger capacity batteries, i was thinkin XS power. or that PCM in the cobalt is not letting the alternator output 100%. I have a smaller belt installed aswell. Lights only dim when the sub amp is close to clipping, thats where I like to normally listen to it so I just got fed up with it on the way in to work today. I have 1/0 ran from the alt to the batteries in the trunk. I dont know what to do. I need some suggestions on what to do next.


Thanks

 

get HID's i have the basically the same thing minus the HO alt and my headlights dont dim at all

what kind of subs btw?

 

I will look into the HID bulbs idea, I Never thought of that. Subs are 2 12" Fi SSD dual 2 ohm in a 4 cubic foot box tuned to 29HZ.

 

HID's are rather expensive. Do you recommend anywhere I should look to buy them?

 

You can get HIDs from DDM Tuning that have a lifetime warranty for like $45 including the relay harness you should use to wire them up with.
