[QUOTE="Doxquzme, post: 8865795, member: 689267"] You don't set gains for the different ohm rating of the woofers you are going to use. The woofer wiring configuration for the amp and the sub determines the resistive load (impedance) it will operate at. What is the low-level output of the HU, what amp, what sub(s) and how is all wired together needs to be established. Once that has been vetted, wired correctly, etc. then gains can be set. Gains are set in accordance with the low level output of the HU to try an match as closely as possible, the input of the amplifier capabilities/limits. They are not a means to increase or decrease volume (and they should not be used this way) so that you don't overdrive the amplifier into clipping. Need the equipment particulars noter earlier for anyone to assist further. [/QUOTE]
