2 subs with 2 amps help

[TacoSauce 10+ year member]

I have 2 12" RE SX subs. I have 1 in my car right now and i'm gonna be building a box to hold 2 of them soon.

I have the 1 running off a Hifonics 1206D, and I just purchased a 1205D(pretty much the same thing) to run the other sub. How should I go about wiring these? With the RCA's and such. I know how i'm going to do the power, but i'm confused with the RCA's.

i had two L5's and two alpine m650's. just run 1 rca cable back to the amps just like before, and put left plug in one and and right plug in the other amp, if you try to run a seperate rca to each sub the subs normally wont hit in the right sequence, not to mention the fact most decks dont have two sub outputs.

That sounds almost too simple, lol.

Can anybody confirm this?? Does anyone else run 2 subs with 2 seperate amps?

both amps have line outs. Just use those.

So you guys are saying to just use my existing RCA cable and just put 1 into each amp?

run the rca from the headunit to 1 amp then another set of rcas from the output on 1 amp to the input on the other.

you're going to have to make sure all the gains and **** are the same.

Okay I got the RCA thing figured out. I plugged everything in and my subs weren't working.

When doing 2 subs with 2 amps, is there any different wiring you have to do for the subs?

I had 1 sub running for like 3 months, so I just wired the other sub the same exact way that one was wired.
