[QUOTE="skittlesRgood, post: 5175613, member: 590546"] im having trouble with me amp... i tested it with a dmm and 60hz tone. set it under the voltage i needed. gain was about half way up. then i put in a heavy bass song and the amp went into protect. i had to turn the gain down below 1/4 b4 it stoped doing it. at that point the voltage only read 20 and i needed 34v for rated power. (eq flat, volume 45/62) i only have 2 guesses: 1. power and ground wires were messed up. i had 0awg + running to the batcap then to a distro. block. three 4awg leading off that. 2 of those went to the sub amp, 1 to my 4 channel. then the - runs all went to the same ground, three 4awg and one 0awg. now i changed it so the - run goes to a distro block so its set up the same way as the + and the batcap has the 0awg grounded still. its to late to test it though. 2. something is wrong with the amp. so since i cant test it i wanted to see if you guys have an idea whats going on. edit: im also getting dimming. lights stay dim on long bass notes. its not really bad but noticable. think just another battery will help? maybe a red top?
