Well, you can either achieve 0.5 ohm load or a 2 ohm load if you want to run it bridged, but that would be extremely inefficient since the mono is 4 ohms. Therefore, the only right way to do it is to wire each up into 8 ohms, then run two per channel. splitting the impedance down to 4 ohms each. You'd only get 310 W x 2 @ 4 RMS. That won't give you enough power. That isn't good because power acoustik is overrated as it is... maybe you should consider a bigger amp. It would be worth the investment and would make the world of difference to your stereo system. A good budget amp company is JBL, in which some of their products might interest you. They are great and are worth the money, but more importantly will give you the power and good clarity that you need. www.jbl.com

dedlyjedly, I think you underestimate the people on this board. I got news for ya, most of the people on this board arent going to get cofused by your simple little explination about running amps in mono and stereo and what this does to your power. Infact I dont think your post really said anything that wasnt already said earlier. I am gonna trust that you didnt mean anything by your post but it seemed very condesending and I cant think of anything I hate more than people talking down to me about things that are the equivelent of the ABC's to me. I am betting most of the other people feel the same way as me. Like I said though, I am sure you didnt mean it that way, right 4 subs to 1 two channel amp - Page 2 -- posted image.

Now that I think of it, Ravendarat, it sort of sounds like he did mean it that way! But maybe not?

I'm with Ravendarat...this isn't a forum full of newbies and you didnt say anything complicated..in fact you didn't say much of anything.

Instead of putting 4 ohms on each channel in stereo mode, put an 8 ohm load in mono on. You're not going to get much for power, though. You can't just run a ton of speakers with a crappy amp.

And since when is half of 600 equal to 400?

I want to apoligize for my stupidity. I was wrong when i said you can wire 4 4 ohm dvc subs to make the amp see 4 ohms. 4 subs to 1 two channel amp - Page 2 -- posted image.

Ravendarat is 100% on target. We know this stuff like the ABC's so don't go insulting our intelligence by filling us with your garbage. Keep the posts clean and to the point.... Wire it all to 4 ohms if you are going to do it sanely. Equation: (4+4)(4+4)/2=1 channel @ 4 ohms. Do that twice and voila you are set. You might not have a lot of power, but it is the only sane way to do it.

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

...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!!!!

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!

sorry for the delayed response, i was enjoying new years in steamboat colorado.

well gentlemen...let me begin by saying that my intent was not to belittle anyone or offend anyone.  i enjoy helping others in this forum ALMOST as much as finding the answers to my questions here! that said, i used the language and the format above in order to stress a point.  although others had hit the nail on the head w/ the ohm's law mumbo jumbo, i wanted to interpret what the truly meant to the threadstarter.

and i stress again, he probably wont be satisfied with the time and money invested and the space sacrificed for the larger enclosure when he hears the system as described.

i stand by my opinion, but am sorry that that message was unclear in my original post.

there are many members here who are proficient in mobile electronics, and my post was not intended for them. 

well...i just seem to ramble, so hope the holidays treated you all well, im off to CES and will most likely not be around for a while, yep, i'm "OUT" like a fat chic in dodge ball!
