Default Should I run one 5 channel or two amps?

Here's what I have

Alpine SPX-177A 6 Components
Frequency Response : 35Hz - 35 kHz
Impedance (Nominal) : 4 ohms
60 watts RMS, 240 watts Peak
Alpine SPS-1629S 6 Coaxial 2 Way Speakers
Frequency Response : 40Hz - 25kHz
Impedance (Nominal) : 4 ohms
Power Handling Capacity (Peak) : 120W
Power Handling Capacity (RMS) : 30W

Getting
Alpine SWR-1021D 10 Type R
Frequency Response : 28Hz - 1kHz
Free Air Resonance (Fs) : 29Hz
Impedance (Nominal) : 2 ohm + 2 ohm
Power Handling Capacity (Peak) : 1000W
Power Handling Capacity (RMS) : 300W


Now I can get one 5 channel Amp to power this which would be

Alpine MRV-F450
MAX Power (at 14.4V,EIAJ)

Bridged 4 ohms : 240W x 2 + 370W x 1
Per channel into 4 ohms : 90W x 4 + 370W x 1
RMS Power (at 12V,20Hz-200Hz)

Bridged 4 ohms : 80W x 2 + 150W x 1
Per channel into 2 ohms : 40W x 4 + 150W x 1
Per channel into 4 ohms : 30W x 4 + 150W x 1
RMS Power (at 14.4V,20Hz-200Hz)

Bridged 4 ohms : 120W x 2 + 200W x 1
Per channel into 2 ohms : 60W x 4 + 200W x 1
Per channel into 4 ohms : 50W x 4 + 200W x 1

Or Run these two Amps
Alpine MRV-F340
MAX Power (at 14.4V,EIAJ)

Bridged 4 ohms : 250W x 2
Per channel into 4 ohms : 100W x 4
RMS Power (at 12V,20Hz-200Hz)

Bridged 4 ohms : 90W x 2
Per channel into 2 ohms : 45W x 4
Per channel into 4 ohms : 35W x 4
RMS Power (at 14.4V,20Hz-200Hz)

Bridged 4 ohms : 130W x 2
Per channel into 2 ohms : 65W x 4
Per channel into 4 ohms : 55W x 4

ANd Alpine MRD-M300 (SUb)
MAX Power (at 14.4V,EIAJ)

Per channel into 2 ohms : 600W x 1
RMS Power (at 12V,20Hz-200Hz)

Per channel into 2 ohms : 200W x 1
Per channel into 4 ohms : 100W x 1
RMS Power (at 14.4V,20Hz-200Hz)

Per channel into 2 ohms : 300W x 1
Per channel into 4 ohms : 150W x 1


The cost difference between the two is $100, being to run two amps, it'll be $100 more.

Should I run one channel amp or two amps?
I'm not looking for really really hard bass, just something decent.

the single amp would be plenty... get a single voice coil 2 ohm sub and you'll get more power to the sub, for cleaner sound. That 5 channel amp is a TANK, my brother has it running all Boston speakers, components in the front and 6x9's in the back... with 2 10" Boston competitor subs and it rocks...

If you want it simple, go with the 5 channel... it'll give you PLENTY of power and it sounds amazing! Save the $100... plus some... you only need one 8gauge power wire, instead of a 4 gauge with a distribution block... and a smaller fuse... saving you more money.

its really up to you. a 5ch is like 2 amps under on chassis. its only minor details that really makes a difference between the two.

after really looking at the specs of the 3 amps...i would run the 2 separate amps with that setup.

as for which sub, i would run it at 2OHM to get the most from that amp. so that would be the DVC 4OHM wired //, to get the final 2OHM impedance.

you're not really looking to blow your ear drums... the 5 channel is more than enough.

And yes, the dual 4 ohm sub, wired parrallel will give you 2 ohms.
