Cut the guy some slack, he's obviously new to car audio, I'm sure you were just as stupid at one point as were all the rest of us.
Thekicker2013 my advice is go to your local stereo shop, and state your situation.
Get rid of all 4 and invest in a decent pair of subs with the same cone size. As already stated running 10s and 12s in the same rig doesn't work, at least not at entry level knowledge.
But to run 2 amps you just need to run another set of RCA, and use a distribution block for the ground and power( seperate blocks for each, or just run another good ground) Just split the remote wire.
