I have a rockford fosgate p3001 mono amp if I hook up 2 4ohm svc subs to just the (a) output connected in parallel would that give me the 300 watts that the amp is rated a@ 2 ohms VS hooking 1 sub to each output (a) and (b) and getting 150 / 2 @ 4 ohms?

if im competly lost please tell me

If you hook up one sub to each output the amp itself will see a 2ohm load.

^^ Right. Using both sets of terminals on the amp is making a parallel connection, so two 4 ohm loads connected this way makes the amp perform into a 2 ohm load. Otherwise, the way most commonly done is to connect the subs together in parallel first, then connect to the amp using only one set of terminals. It's exactly the same either way. It will be the rating of your amp at __watts X 1 @ 2 ohms.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

So no advantage either way?

nope, may as well use both sets of terminals, generally looks cleaner
