Okay so i had made up my mind on which amp i would like to get. I plan on getting the Alpine MRP-M2000
http://www.alpine-usa.com/product/view/mrp-m2000/

I also will be getting 2 Alpine type R 12" subwoofers in a custom ported box with seperate chambers/ 2.0cu ft in each chamber and the box will be tuned @ 32Hz if this info will help.

Now with this amp which Alpine type R should i get?
*Alpine SWR-1243D
http://www.alpine-usa.com/product/view/swr-1243d/
OR
*Alpine SWR-1223D
http://www.alpine-usa.com/product/view/swr-1223d/

With all the different ways of wirign such as parallel..Ect im confused with the "ohms" ive read that 2 ohm subwoofers can be wired as either 1ohm or 4ohms and that 4ohm subwoofers can either be wired at 2ohms or 8ohms...I dont know if this is true that is why im askign you guys.
I want to run them @ 2ohms so im sending each subwoofer 1,000Watts RMS...As the amp specs say-->Per channel into 2 Ohms: (@ 14.4V Ƈ%THD+N, 20Hz - 200Hz) 2000Wx1

So my 2 questions are:
1.) Sould i go with the 4ohwm subwoofers(SWR-1243D) or the 2ohm subwoofers(SWR-1223D)
2.)Does anyone have a Picture/Link of a wiring diagram that is best for this?

that alpine amp :

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

* Per channel into 4 ohms: 1500W x 1 (0.08% THD)
* Per channel into 2 ohms: 2000W x 1

if u use it at 2ohms then thats too much power for them however u can buy subs that wire up to a 4ohm load & have that amp put out 1500wrms at 4ohm

personally i wud buy this instead since its about the same price

for this sundown amp u need the Alpine SWR-1243D model ...

Okay well i thought about it...I see choices that i like.

http://www.alpine-usa.com/product/view/mrp-m2000
*I can either got with the Alpine MRP-M2000 and wire:
Per channel into 4 Ohms: (@ 14.4V Ƈ%THD+N, 20Hz - 200Hz) 1500Wx1
-This will be over powering them just a little bit.

http://www.alpine-usa.com/product/view/mrp-m1000
*Or i can go with the Alpine MRP-M1000 and wire:
Per channel into 2 Ohms: (@ 14.4V Ƈ%THD+N, 20Hz - 200Hz) 1000W x 1
This will be Under powerign them by a little bit.

If i go with the Alpine MRP-M2000 and wire:
Per channel into 4 Ohms: (@ 14.4V Ƈ%THD+N, 20Hz - 200Hz) 1500Wx1
1.) Which subwoofers do i get? SWR-1243D or SWR-1223D?
2.) Which amp wiring diagram will i be going by?

The reason why ive been leaning more toward the Alpine amps is that i know for a fact that they are under-rated and acualy give out more RMS power and there is absloutly no bad revies about them...All great reviews. I know nothing nor ever heard of sundown amps but i guess ill look into them.

Also the SAZ-1500D - Sundown Audio 1500W specs:
Rated power output
RMS power, 2 ohm linkable/dual mono
3000W x 1CH
RMS power, 1 ohm mono
1500W x 1CH
RMS power, 2 ohm mono 800W x 1CH
RMS power, 4 ohm mono
400W x 1CH
@ 2ohms this amp will be giving my subs 400watts each...I dont want to under-watt them

That is not correct. the sundown puts out 1500 @ 1 ohm. So get dual 4 ohm type R's and wire them to 1 ohm. you will be seeing a little over 600 rms to each speaker which is perfect.

You don't need to stay with alpine just because you have their drivers... IMO there amps are nice but a little expensive for what they are. Like others suggested, get the sundown (better quality than alpine IMO) or get a audioque 1200D -- can't go wrong with either and a better bang for your buck in the long run.

did u not read my 2nd post

if u want to stay alpine for amps & not mind the cost then this wud be the perfect match

http://www.onlinecarstereo.com/CarAudio/p_25488_Alpine_PDX-M12.aspx

a bit pricey but u wont have to worry about which ohm subs u buy as long as both are the same exact model


personally i wud get the sundown sax1500d with the 1243 instead ...
