Right now I have one Profile AP1000M mono amp and one 10" Rockford Fostgate P2 4 ohm sub. I want to add another ten. Do I need a different amp? Is there a way to wire everything up and have enough power for both of the subs and still sound good? At 4 ohm's the amp is rated at 310w x 1 and at 1 ohm its rated at 500w x 1.
Would you go from amp(+) to sub(+) then to the other sub(+). Same for the negative? How would that sound?

 

Here you go this should help....Series Vs. Parallel

 

That's a nice read right there. Definitely should answer your question landshark16. Wish I had that just a few weeks ago when I was learning.
