Re: Question about wiring an amp and subs.
You have two ways you can do it...
One would be to wire each sub to 2 ohms and put one on each channel of the amp.
Alternatively, you could wire each sub 8 ohms, then wire them together for a final 4 ohm load that you could connect to the bridged connection on the amp. This makes it easier to set the gain as you only have to deal with setting it on one channel of the amp.
