1 amp to 3 subs

HI all

i have a 4ch 1200Watt legacy amplifier and i am trying to hood that up with three 10s, thumps, 4 ohms each. 

wat i did was that i put all the speakers in parallel, meaning take all positives from the speakers join them together and hook that up to the amp and the same for negatives.   So basically the amp is bridged.

i was wondering that the amp is 2ohms per channel and 8 ohms bridged and my woofers are 4+4+4=12ohms. would that be ok?

What you did was not right. The parallel wiring you did made the resistance go down to 1.33 ohms if all the wires are connected to one (-) and one (+) terminal on the amp. Not too many amps out on the market can handle a 1- 1.33 ohm load effectively. If you want a 12 ohm load wire the subs from (-) to (+)to (-) to (+) to (-) to (+) and to the amp

Depends on how your amp is setup.  If it is only bridgeable down to 2 channels then you are kinda screwed....  In that case, your only options are to keep it on 4 channel, and leave one channel open; or bridge it into 2 channels, then use one of the 2 channels for all three speakers.

jeff  the speakers are sharing one chamber

dang it... I typed everything up, hit send, and it's not there....

Anyways, in the words of Elmer Fudd:  vewwy vewwy bad.

You don't want to run speakers in series if they are sharing a chamber.  It can cause problems.

In order to help fully, we need the make and model of the amp. Some do drive into 1.33 ohms but the problem you will have is inefficiency and the amp running hot (and shutting down early).

If its a class D amp it should be OK.
