CH1/2 - Leave XOVER off for 6 x 9’s (set to full on the switch) CH3/4 – SET XOVER to HPF, dial set between 150 and 180 hz
Approx size of sub box will be 5” tall, by 10” deep, by 38” wide with subs pointing upwards, and the box placed directly behind back seats and in front of the shock towers Also, I will be wiring the two subs in parallel which will give 2 ohms at the amp and 500 watts of power I will disable (set to FULL) the crossover on the sub amp
160hz via from RCA amp for 4”
Xover below 80hz via from 3.2 for subs
Xover above 80hz via 3.2 for 6x 9’s x 4’s
it also seems to me that we will be leaving the xover on the digital audio amp to be off. Because we have already told the audio data to stop at 80hz...YES, this is how it is.

2. Grounding Head Unit RCA AMP SUBWOOFER AMP Relay Ground Dist Block
Will need ring terminals and/or spade terminals for making some of the connections, and the grounds on the amps will be wired directly into the screw-down connectors on the amps

I believe both the THREE.2 and the Head unit already have pre-wired 16 GA grounding and power wires on them that I cannot change since they are directly connected to the units themselves

I would like to use a connector like this one shown here for the relay, but I don’t know if it will have four outputs on it or not. To feed all four of the devices that need a remote turn on signal. If not I need to make my own. Or just splice in a few power remote turn on wires to the outputs of this connector
