[QUOTE="AlterEgo99, post: 6721079, member: 610253"] Yup, I agree with DidUHearThat? I've got an '08 Silverado with a stock 145 AMP alty. There IS a reason they put in the size alternator that they do at time of manufacture. Anyways, I too have 2 10" JL Audio subs and am running 1,000W Max RMS. Not huge by any stretch, especially compared to some of the folks here on CA. Anyways, I was getting light dimming on high volume and big bass hits. So, here is what I did. 1. Big 3 - with 0 gauge Knu wire people! 0AWG! Nothing LESS! Stock was 8AWG if you can believe it. I removed all of the stock wiring to the battery, alternator, chassis and block and replaced with 0AWG. 2. Upgraded OEM AC Delco battery with a Kinetik HC2000. 3. Added 2nd Kinetik HC2000 (there was a spot for a second battery under the hood, so I added it) After #3 was done, no more dimming. At each step the dimming was less and less but after #3, the dimming was gone. Oh, also, I had a real slight alternator whine I was also fighting and when I added the 2nd battery that disappeared too. If I add more wattage to my system in the future, I may look at an HO alty, but for now it is keeping up just fine and voltage is typically right around 14V. [/QUOTE]
