I still have a little bit of dimming,(NOT MUCH) with my 240 amp...It only happens on "Punchy" bass (voltage goes down to like 13.9, and its not the headlights just my gauges on the dash.....But I can play a 35Hz tone forever and my voltage doesnt drop below 14.5...

i get a constant 14.5 volts at my amp, playing a 43 hz. tone, and full volume with headlights and defrosters at an idle. i have no expensive optima battery or capacitor either //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif
