2 subs connected to a 2 channel amp?

Is that what the instructions say?

I would love some instructions, if you know of any. 

Subs I am looking at only have high level in, not out, FYI. 

IF I’m reading you correctly- you have a pair of speakers, and a pair of subs, one sub dedicated to each speaker.

If so, you need a speaker wire to to each speaker, and a speaker wire to each sub. The sub may have two inputs ( two positive, two negative), but you’ll only be using one set of them. There are usually two high level inputs on the back because often only a single sub is used, and it’s a convenient way to get both left and right signals inputted.

If this is the case, reply back and it’s all pretty straightforward to explain.
