Help, I am trying to see if two amps can run three 12's ? I already have the amps and dont want to have to buy another one. It has a bridged output on the amps but I dont know how to hook it up. The amps are an old memphis competition series, they are 2 ar-hc100. They are rated at 1096 watts at 1 ohm.

Are the 12's SVC or DVC ? You should not run 2 separete amps to 3 subs because the amps () can not perform in unison and one of the amps will have more power than the other causing the subs to perform out of synch. If the amp is 1 ohm stable you can probably run all three subs off the one amp, depending on the voice coils and how many each have. Let us know.

Both the amps have a bridged output rca type connection and I was wondering how if this is what is used to join them together and if it could be done. The amps are 1/2 ohm stable. If I use three on 1 amp should they be svc or dvc? Also Jeff is there a diagram to change the amount of ohms seen by the amp for the three subs together. LIke make the amp see 4 ohms when just riding and 1 ohm if i decide to compete? If so please help, not that knowledgable with relays.

Thanks
Hiram

What type of amp's are they?

Here's some diagrams... (I couldn't get the last one, but you can also wire 3 4ohm DVC's in parallel to get a 0.67ohm total load)
