How would i wire this when i have 4 channel RCAs and this only has 2 rca input?

It has 2inputs...and 4 out. That's how

How can I run OUT1 in stereo? Input as A + B?

On the DSP 2.4X, you can only choose A or B or A+B(mono) on each output (which will effect both RCA outputs on that button). For example; Output 1 A Output 2 B. But the A+B does not make one of the RCA left and the other right. That will make both a mono signal. You can not control each RCA individually with the 2.4X. In the case where you need that much control, look into the DSP 2.8X.

Can you tune 1 channel for subwoofer amp alone?

Yes u can have 1 ch for subs or 2 ch for subs
