I have two 1 ohm stable amps and two 4ohm DVC subs. From what I have read here, I have to wire the subs together to run 1 ohm. If I do that how would I hook up my two amps to the one input to the subs?

You have the possibility to run both subs in parallel on one amp for a 1 ohm load. Or parallel each sub to it one amp for a 2 ohm load.
What amp subs are you working with?

They are Legacy 2000w subs and Legacy 3000w amps. What will be the noticable difference running two ohms as opposed to one? ------------- 89 Prelude Si2.0

Well, it's Legacy so you will not see anywhere near those outlandish power ratings. If you want to run both amps, then connect each sub to its own amp as a 2-ohm load being sure the electrical phase is the same and carefully set the gains on each. Make sure both amp is receiving the same signal and is set up the same way, etc. You'll get what you get and with that brand there is no way to know what that might be. ------------- Support the12volt.com

My friend bought a couple cheap "1200 watt" legacy subs(red ones, dont know much about em) off ebay and he blew them with a 500 watt eclipse amp. Just to tell you something about their cheaper stuff.

Legacy is not a good brand.

hello i have 2 memphis subs pr124d 12'' and recently purchased a Memphis 16-MCD250 - Memphis 250 X 1 Class D for the subs and i have a interfire amp for the 6x9 and 6.5 but my question is that rms each sub is 250=500 amp is 250x1 but is it possible to connect another Memphis 16-MCD250 - Memphis 250 X 1 Class D to the other sub basically one class d for each sub since i already have one so i dont have to buy a bigger class d? so it would be three amps all together if this is possible one class d for each sub thanks hope this isnt a stupid question...

Get a distribution block to split the power cable between the amps.
The static im not sure...Re-do your grounds possibly? Someone else here will for sure help you out on that.
What impedance are those subs?
Anyway you would wire each subs to each amp.
