Default ED NINe.1 VS Alpine MRD-M1005

Sorry for the bit of overlap but since I just want this topic to be a discussion of amps with the tC I decided to start a little poll/discussion.

The choice is pretty much a tossup between the Alpine and the ED amp as they are about the same price on ebay for the alpine or ED via their website. So price being equal (Yes I know I wont have a manu-warranty on the E-bay purchased one alpine amp) which is the better choice?

If it matters I plan to use a Alpine Type-X 10" 4Ohm Dual Voice Coil sub wired in parallel for a final impedance of 2Ohm's.

I think the ED is a better choice because its rated at 12.5V and the Alpine is at 14.4V where as the tC only puts out 13.4 or so (measured with my own DVM).

Would the NINe.1 put out MORE power than listed if it's run at 13.4 or would it trim off that extra power and still only put out the 12V ratings?

Important specs for the Alpine are here:
RMS Power (at 12V, 20Hz-200Hz)

* • Per channel into 2 ohms : 700W x 1
* • Per channel into 4 ohms : 500W x 1

RMS Power (at 14.4V, 20Hz-200Hz)

* • Per channel into 2 ohms : 1000W x 1 (1% THD)
Important specs for the Elemental Designs NINe.1 are here:
Amplifier Specifications
Power rated at 12.5V
1200 x 1 @1Ohm
900 x 1 @2Ohm
450 x 1 @4Ohm
Height : 2.25"
Width : 9.85"
Length : 14.70"

yes. ed amps are extremely underrated and typically push around 1000 @ 2 ohms and around 1350 @1ohm. I think u would be fine. PLUS u get a 3 year warentee.

i would go with the ed amp.. the alpines tend to be picky about going into protect mode at higher volumes even at the recommended ohm load.. happened to me on a 4 channel alpine awhile back

Alpine MRD-M1005 are under rated I have never seen one as low as the specs quoted on paperwork. They all have a hand written spec sheet in the package telling you what the power output actually is. I have one in my stock room at the shop I will look to give you an Idea of what kind of output the actually have
