Alright so I have been searching around the forums for months now trying to build a system.

I have a Kenwood DDX-418 head unit and 2 pairs of bargain 6.5 coaxial speakers
I have KnuKoncepts 4 gauge OFC wire (can upgrade if needed)

I have a budget of about 750 for the sub/subs and amp

I was looking at the Alpine MRX-M110 for the amp, but I think there might be better out there for $275 (Alpines Amazon Price)
(Alpine Electronics of America, Inc.)

I'd like to find an amp that is 2ohm stable preferably

So I need suggestions on the amp

Then the subs I were looking at

-2 Alpine SWR-1223D
(Alpine Electronics of America, Inc.)


-2 Rockford Fosgate P3D2-12
(Rockford Fosgate P3D2-12 Punch P3 12" subwoofer with dual 2-ohm voice coils at Crutchfield.com)

-2 Image Dynamics IDQ12v3 D2
(http://www.imagedynamicsusa.net/files/59632729.pdf)

-1 Rockford Fosgate T1D4-12
(POWER Subwoofers - T1D412 - Rockford Fosgate®)


And do I want a nice Cap or second battery
I plan on doing a big 3 upgrade as well

I drive a 98 Maxima so the trunk is fairly good sized
I plan on building a custom ported box

I am open to any and all suggestions
