After your Big 3 it would be a good upgrade of sorts to drop a dry cell in for your starting battery at least. And grounds, always double check your grounds, and make sure your ring terminals are securely attached. Crimping works but do it right the first time, I personally solder mine with a propane torch.

If your grounds/Big 3 are up to par (instead of grounding your engine block, ground directly from where the alternator mounts to the engine block, more efficient in my testing), and you have a dry cell in front, and you're still dimming, possibly get your alternator checked. Mine was in shabby condition when I got my 05 GP at 59,000, so a 1000w RMS Rockford Punch amp fried the thing on my way to Ocean City, MY. Needless to say, driving off of a dieing battery with no charge (maybe 10v) eff's with all the electronics and makes for one very... edgy drive.

Your next step after big 3 and dry cell up front is a HO Alternator and a second dry cell isolated in the back, but you really shouldn't need all that if the previous is done well.
i 100% agree and anyone running 1000rms should have at least a ho alt or aditional battery
