Connecting Two Subs To One Class D MonoAmp

I was wondering if it was at all possible to connect two subs to one single-channel amp. I think I read somewhere that you could do this but I don't remember if it was expounded upon.

Thanks! I appreciate it. I'm gonna check it out right now.

The only problem I'm running into is this: the guide doesn't say if you can hook up 2 subs to 1 channel. I just shows 1-7 or so subs connecting to an amplifier. It doesn't mention how many channels the amp has. I want to connect 2 subs to one channel on a monoblock amp.

If the amp has one + and one - then you need to wire one sub to the other sub and then wire one of the subs to the amp.

Ok, I think I get it. Is there a limit on how many subs can be connected this way?

One more thing. If I'm gonna do this below using the Dual-4 Ohm Subwoofer option. What should my amp's ohms be? Hope I worded that correctly lol

Also, I'm assuming that this illustration is showing a monoblock amp.

2 DVC drivers with Voice Coils in Series / Parallel

Connecting the two voice coils of each driver in series (+ to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances:

Dual-6 Ohm Subwoofers: 6 Ohms

Dual-4 Ohm Subwoofer: 4 Ohms

Dual-2 Ohm Subwoofer: 2 Ohms

Dual-1.5 Ohm Subwoofer: 1.5 Ohms

If you wire two DVC 4-Ohm subs like in the diagram it will result in a 4-ohm load at the amp... Just like it says. What amp and subs do you have?

I haven't bought any yet. I want to be better informed before I make that purchase. I don't like returning items. But I'm looking at some JL's and RF's. Don't know yet.
