I recently bought the P6001bd and I am curious about a few things. This is a Mono amp yet it has two inputs for the subs. I understand that internally the signal is parallel. Here is my question. Can I run two subs in to the A channel and if so will it break it down to a 2ohm load or will I need to use both channel A and B and leave it at 4ohm. The subs I own are 12 inch Alpine Type E's. Any advice would be great.
