If I set my gain with the dd1 prior to doing a big 3 upgrade would my gains need to be reset after the big 3?
Now after installing my DC275xp I can say set gains with engine running, my amps put out a lot better at 14.6-14.8 (alt hot) than with engine off at 12.5 volts. Voltage is at the amp with a stinger volt meterIt wont matter your car does not have to be running to use the dd1 results will be the same
