[QUOTE="THATpurpleKUSH, post: 7559663, member: 615398"] 7 pages of nonsense and no one has explained what the purpose of the gain setting is. It is NOT a volume knob. It is there to match the output signal of the source unit. For example if your headunit has 2.5v preouts, then you want the gain on the amp to be set to 2.5v (NOT volts AC) Unfortunately most amps don't have the voltage readings printed and instead have an arbitrary number system or even just a visual symbol indicated less to more. I have a Rockford p1000.1bd and it has the same looking settings and I have 2.5v preouts, same as OP. My gain in about the same place as op after he reset it. Mine is set for around 37vac or 1400wrms x 1 ohm which is what my birthsheet reads. I have a 130a alt, 1 run of 4ga and no electrical upgrades and I'm running a 2ch to the front stage and my **** is maxxed out. I don't push my volume past 50-60% though so I dont really have much of a voltage drop unless I burp a 0 db tone. [/QUOTE]
