Ohm Question

[zerohertz 10+ year member]

I've got two 1600watt max 12" subs, each 2 ohm DVC. The RMS on the subs is 800watts. I have a 1600watt D Class mono amp. At 4 ohms, RMS is 500 and at 2 ohms, RMS is 900. Should I just be hooking up a single voice coil on each of the subs and running them into the amp (The amp has inputs for two subs). Or, should I hook up both voice coils on each sub and then run them into the amp?

Ok mono amp with 900 watts out into 2 ohms. 2 dual 2ohm subs. Wire the voice coils in series on each sub. That will be 4ohms. Then wire the subs to each other in parallel that will give you a 2ohm load to run your amp into. 900 watts to the speakers will give each 450 watts...

Can you explain wiring in series and parallel so i can set it up like you suggested? Do you mean hook up both positives and negatives (+ to +, - to -) on each sub and then run a single positvie and negative from each sub into the amp as if i was bridging a 2ch amp?

No the opposite + to- to + to - on each sub. That will series the voice coils and give you 4 ohms. You will have only 2 leads coming off the sub. 1 pos and 1 negative lead. Then wire the two + leads together 1 from each sub. Do the same with the negative leads. So you end up with 2 neg leads and 2 positive leads that hook to the terminals on the amp. The voice coils are in series or one after the other. But the subs themselves are in parallel..
