PPI P1000.1 Wiring Question

[96Firebird 10+ year member]

I feel like an idiot for asking this, but the manual had me confused...

I have 2 SA-12 D4 subs, and want to wire to a final load of 1ohm. Reading this, it got me confused. Right now I am thinking I need to wire the subs in parallel (+ to +, - to -), then wire both + together and both - together, and then use only one if the +/- outputs on the amp. Does this sound correct?

Thanks for any help.

correct. Wire the subs in parallel, then parallel all wiring to the amp.

Might be time for Precision Power to update their manual because that **** is hella confusing

I think I got it figured out, with help from another forum as well.

Each DVC 4ohm sub can be wired in parallel to a 2ohm impedance, and then I can use both outputs on the amp. I could also wire it the way I said before, either way would work. Looks like the amp parallels the outputs.

But I do agree, they make it very confusing.

Thanks for the input.

It looks straight-forward to me. Most mono amplifiers with 2 positive and 2 negative +12V terminals have the like pairs of inputs joined inside the amp, which is why the "NOTE:" paragraph is included. Two 1 ohm subs wired in parallel results in a 0.5 ohm nominal impedance, which the amplifier can't safely handle.
