Is it normal for my class A/B amp to pull more current than my sub amp? I have never seen this in any other system I have put together... at least I have not noticed it. Specifics... My US Acoustics Barbara Ann 4 channel class A/B amp is getting full range signals of 60hz and up from my head unit. When I play a few specific songs with strong midbass up to and above 120hz, which is what my sub is crossed over at, Barbara Ann yanks a crap ton of current from the electrical system. I verified that it is that amp by turning off the sub from the head unit. Is this normal? Is class A/B that much of a power hog? I am talking 2V+ on 3 different gauges. The dash, the cap and a multimeter. I have to REALLY push the sub amp to make it drop voltage on the gauges at the same volume by cranking my remote gain knob. Thanks everyone.
