RCA Pass Thru

[AnthonyO 10+ year member]

Aight, I am only bringing this up for ease of install.

My head unit has front, rear, and subwoofer out. It also has built in crossovers and time alignment
My 4 channel amp has a pass thru.

Would you use the head unit subwoofer out and run RCA's back or just use the pass thru on the 4 channel?

I never use that pass through or out terminal on the amps
Always run right from the HU
Besides I think you would loose the controls for the subwoofer if you don't run it from the sub out on the HU
