You must have something out of phase.

First of all, are you running the subs parallel or running a sub to each channel. Another thing is that you should check the ohms on the subs to see if they are reading 4ohm. The reason I say this is because I have 4 Infinity Kappa Perfect 12's in my Explorer.

I am running the subs one per channel, what do you mean by "Another thing is that you should check the ohms on the subs to see if they are reading 4ohm. The reason I say this is because I have 4 Infinity Kappa Perfect 12's in my Explorer. "

The reason I say that because if one of the subs is reading lower than 4ohm then it will recieve more power than the sub that is reading 4ohm. Less resistance means more power for the sub.

And in my case if 1 of my 4 subs was reading less than the rest than one set of subs would recieve more power than the others creating a different sound.

after messing with the gains and setting them properly both subs sound the same, now the problem i have is that when i have one sub on, doesnt matter which, the spl is higher than when i have both on. like if i put the right RCA the right sub is loud but if i put both in its quiet again, if i plug in only the left RCA the system is loud again. any ideas?

Just adding my 2 cents on the out of phase concept. I had the same problem, and I couldn't figure it out either. What I didn't realize was that I accidentally wired one of my subs the reverse of the other one, meaning the positive terminal of one of my subs was going to the negative connection of the amplifier while the other sub was wired correctly. What this did was make my subs travel in opposite directions, practically meaning one was pushing in and one was pushing out. Just make sure that your wiring for each sub agrees with the other one. Follow each terminal of the subs and make sure they go to the corresponding terminal of your box, and that each terminal from the box goes to the corresponding terminal of the amp. I know it sounds like something simple, but believe me, its something simple to overlook. Sorry if this was no help.
