I have two type E 12" Alpine and two Legacy 10" subwoofers with a V-power 400 watt mono power Amplifer. I have my two 12"s hookedc up to the amp but I want to add the two 10"s. The only problem is that I'm trying to get it all at two ohms. there all four ohm subs. My amp specs are:
MOSFET Output Transistors, Discrete Preamp Stage, Double Buffered Preamp Input Circuitry, No Current Limiting, Blue Power Status LED, Speaker Level Inputs, Gold Plated Connectors and Terminals, DC-DC PWM Power Supply, MOSFET Power Supply, Adjustable Gain Control, Thermal Management Processor, Bass Engine (Variable LP Crossover, Bass EQ), 400W x 1 RMS [2ohm @14.4V (1%THD)], 800W x 1 (Max).

not possible to get 2ohms out of this setup......only way to get 2ohms is to run one pair of subs in series since these are svc subs........im sure you could hit a lot harder with just one pair of subs anyway....these alpines are 250wrms each and would be close to the power output on your amp...if you added more to this amp you would be starving all the subs for power..,,see what im sayin?

You can't get 2 ohms from 4 four ohm subs.
You can get 1 if you wire them all parallel
you can get 1.6 if you wire a pair in series to 8 ohms, then wire the pair along with the two single 4 ohm subs all in parallel to the amp.
or you can get 4 ohms if you wire both pairs in series to 8 ohms, then wire them in parallel to the amp.
Honestly you should not try to run all 4 on the same amplifier. You really shouldn't mix sizes either. If you insist though, run each pair on a seperate amplifier.

yea what he said...with the details n stuff..

so would it be possible to hook up my two twelves at anything less than 4 ohms besides geting a new amp. plus is there a diagram i could look at just to see that one ohm idea?

heres a link that allows you to view different combinations to figure out the ohmage and wiring..
