4 subs to 1 two channel amp

if your amp will go down to 2 oms bridged (which is not likely) then run two sets subs in series this will give you a set of two at 4 ohms and the other set of 2 at 4ohms now you can run this to each channel or run these 2 in parallel in to the amp and you will have one setup with all 4 at 2 ohms

that's the only option

Here is the other and safer option. Note that this diagram is for one channel and two subs only, thus duplicate it for the other side. Your amplifier is not going to be 2 ohm mono stable and if it is wired as recommended above, you will be buying a new amp in short order.

Wiring Option #2

(THOSE) 4 12'S + (THAT) 1600 WATT AMP = A SYSTEM THAT DOESN'T PERFORM AS WELL AS YOUR OLD ONE!!!

don't believe me.....well...read on

okay, here's the deal...forbidden is in fact correct with his diagram above. obviously you will have 2 subs connected in this manner to EACH channel of the amp, hence we refer to the final load as "4 ohm stereo". forbidden was most likely correct (i have not confirmed) in assuming that the power akoustik will not handle a "2 ohm mono load". thus, the minimum stable load is "4 ohm mono".

i know im starting to confuse everyone, so my logic above amounts to the fact that you'll ONLY utilize all 1600 watts (peak by the way) @ a 4 ohm mono load!

the 4 ohm stereo load you will use will only yield HALF of the amp's potential!!!!

so instead of running 600 watts peak (i can only assume your old amp liked to exagerate power as well) to each sub like you had before, youre attempting to run 400 watts peak to each.

unless you were seriously overpowering the subs previously, i suggest a different amp (something that will deliver the power you want @ 2 ohm mono)

i know this sounds rediculous to some of you, but designing an efficient system is a lot more difficult than maximizing the watts!
