[QUOTE="02WS6, post: 8691523, member: 678581"] You are completely correct and apologies I should've been more clear with my response. Pre-out voltages will have a definite effect on setting the gain for your amp. Everything Boomin said here is correct and setting your gain with a DMM to 600-800 range would be even better than my 1k suggestion. 12.8 is perfect resting and 13.8-14.4V is the charging voltage recommended with the vehicle running. I think you may of misunderstood what I was trying to say. I'll try to clarify better. OP said the Amp went into low power protection while he was play a song. The undervoltage protection for that Amp comes on at 9 Volts. ([URL]https://www.taramps.com.br/en/produto/md-3000-1-2ohms/[/URL]) OP said he assumes the Amp hit that 9 Volt under protection level while the truck was running: While I find it hard to believe he was able to get the charging system down that low, in the unlikely event that he did, I wanted him to understand the amount strain that he was putting on the electrical system and that a resting 10.5V was 0% charge. Hopefully, If he understood a resting 10.5V was 0% he would understand how bad it was for his car if he was running it down into 9V while running. (I can only imagine how happy his alts rectifier was!) I recommended to NOT shut off the truck right after doing something like that (if he did it again) as his car battery would effectively be dry and he would be unable to start it again without a jump.That is beyond any other potential long term damage that it may do to his alternator or other systems on the car.
