Amp Decisions

Ok I just got done with an install in a buddy of mines mustang.  Turned out great! (Or at least I think so.  Ill post pics) Anyway Im now looking for amp combinations for my new set-up. 

Im going to run 4 Infinity dvc 1030w 4ohm 250  rms subs

The sub amps i was looking at are Hifonics BX1500D - $240.00 plus shipping

This amp is rated at 1500w x 1 at 1 ohm. 

Correct me if im wrong but 4 4ohm subs par = 1 ohm right?  If so the power output of say 1500w is divided by 4?

Second choice is TWO Hifonics ZX6000 2 channel amps. $160 each / $320 plus shipping for two

This amp is rated at 300w x 2 At 2ohm.

So my question is even though the first option would be less expensive, would it be better to run the 2 amps at a higher ohm rating or 1 amp at a lower ohm rating... .

Sorry about the long post but figured id try to explain!

You are correct in regards to how the power is split.  One thing that I noticed is that you are going to be running 4 DVC subs.  This would give you multiple set-up options.  I am assuming that they are 4ohm per voice coil.  You can wire all of them up to present a mono amp with a 2-ohm load.  This would not give you the full 1500 watts but it will be cleaner than presenting the amp with a 1-ohm load. 

Or you can use two amps and wire each side to see a 2ohm load from the subs.

With all of this said it all depends on what you are looking for.  Is it clarity or boom.  Running a 1-ohm mono amp at 2 ohm might be cleaner than a stereo amp at 2ohm.  This is only because distortion increases with most amps when you come closer to there limits.

wait 4 dvc subs wired in parallel produces a 1 ohm load. . .  right?? how do you set it up for 2 ohm.  Parallal and series? 

umm no, it would be a 8 or 2 ohm setup.

Series = 4+4 = 8

Parallel = 1/(1/4+1/4) = 2

check that, it would be a 2 ohm setup wired with each sub in series and all the subs wired in parallel series parallel.
