Hey guys Im still working on the never ending audio system in my truck (will eventually get some updated pics on my build thread) But I've ran into a problem, or maybe my expectations were too high.

I have upgraded to 2 yellow tops under the hood and a PowerBastards 240A HO alternator. I have 0/1 ga wire running from my Alt to the battery. I haven't done the other Big 4 wire swaps yet. I only have one 0/1 power wire running to my distro block on the back wall and 4 4ga running out.

Well I has helped some, but I am still getting serious light dimming when I get into some heavy and loud bass notes. I was assuming that I had upgraded enough to eliminate that.

Will the rest of the big 4 wire swap help? Should i run a power wire from the alternator to both batteries? any suggestions will help. Thanks guys

 

yeah mine dim to but not enough to bother me, i think its funny its like a disco theme in my truck with all the base

 

big 3/4 will solve this
for a proper electrical circuit you need to have the same size ground as power wire
stock grounds are barely 10 gauge, just upgrade your grounds in the big 3 and then report back.
