After a month of research I have my system figured out. Any flaws?

[dpu2014 10+ year member]

Ok Im about ready to order everything I need for my system. Im pretty sure it all matches up and Im gettin the right stuff. If you have any comments or suggestions plz let me know.

Here it is

Amplifiers

Alpine Mrp f450 70watts x 4channels @4ohms

Kicker Zx1000.1 1000watts x 1channel @2ohms

Speakers

Front: Polk Audio 6.5" momo components 125 watts. rms

Rear: Polk audio 4 x 6 coaxials 50 watts. rms

Subs

2 12inch Si MagsD2

Any problems? I need some confirmation from people who really know what they are before I put a huge dent in the pocket. THANKS //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

i don't think thats enough power for 2 12" mags

now throw another amp in there, and you have a really nice setup

That's plenty of power for the mags. Especially if he's talking about the upcoming version.

I ran mine off of 300 rms for 2 weeks //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

I'm that good.

J/k, I'm referring to the second gen. mags.

o well dang it you got me excited. Ha allright any other comments? I can run a dual 2 ohm at 2 ohms right? Some kid told me you can only tun them at .5, 4, or 8? Sounds like bs to me.

the second gen mags that people would run about 1200 off of?

They are compared to the FI fully loaded Q's as far as power handling

i don't like that if the new ones are only takin 300watts well

dual 2 vc wiring diagrams can be found on rockford's wedsite, or just google it , but they can be wired to 1 or 4 if i remember correctly...

i just checked it and I can wire 2 of the subs to a 2 ohm load. If I only wire 1 of them then it must be a 1ohm or 4 ohm load.

You can wire them to either a 2 ohm or a .5 ohm load.

Wiring in series, you add the resistances. Wiring in parallel, you divide the product of the resistances by the sum of the resistances.

So say you have two dual 2 ohm subwoofers. 2 ohms in parallel with the other 2 ohm coil is 1 ohm. (2*2 divided by 2+2). Then this 1 ohm load in series with the other 1 ohm load produced by the D2 subs is 2 ohms (1+1). If you parallel these two loads, you would get .5 ohms: (1*1 divided by 1+1, or 1/2).
