[QUOTE="bbeljefe, post: 8257662, member: 655960"] First of all, a correction. Turning the gain down does not "give" the amp more power and turning it up doesn't take any away. The gain is meant to match the source signal voltage to the amplifier's input sensitivity. Once set (properly), it should not be changed regardless of the impedance or the number of the subs. You mentioned that the gain is currently set at 3/4. Unless you have a line out converter being fed by a factory head unit, that is way too much gain. If it's an aftermarket head unit with the front stage powered by the head unit, the gain may need to be about half way up but if the system is all powered by external amps, it should be between ¼ & 1/8 of the way up, depending on the preamp voltage your head unit sends.
