It will do it either way, but only on very loud bass drops that are pushing close to the full 1400 watts. That is something to consider, my alt does 160A idle and 250A max, which would be somewhere around 1500 RPM after doing some math with DC Power's numbers, I'll see if revving it up makes a big difference. The dimming isn't too bad though, only on those sine waves :P
Tomorrow is supposed to be free of rain so I'll double check all my grounds just to be extra sure that isn't the issue.
Anyone have any advice on the resistors or capacitors? I'll be doing the headlight circuit either way to take advantage of my... interesting bulbs. HIR2's http://www.amazon.com/Philips-HIR2-S...&keywords=hir2
They can be modified very easily to be placed in both lows and high's (at least in my 05), a bit brighter, much whiter, and same beam pattern.
In my opinion, the beam pattern on our OEM headlights blow. My right high beam leaves a dim "hole" right above the cutoff of my low's. Annoying.
