Wiring Subwoofers??

[JayMax03]

I have (2) Cerwin Vega V-Max 12.2 subwoofers http://www.cerwinvegamobile.com/VMAX12.php

I'm hooking it up to a Cerwin Vega EXL Series 1200D amp to get a 1 Ohm load in parrallel wiring http://www.cerwinvegamobile.com/EXL1200D.php

I'm I doing this right I know its not the best way of picturing it but I don't have a camera right now... about the amp? it only has one speaker terminal and I never seen that before (both negative and positive) does it still work the same way?



I'll upload some pics tomorrow just to get a better view... I have to go to work in 30 mins I know how to do the rest its I never seen an amp like this before... so thats why I asked this question. I haven't wired it to the car yet I got to get my D-Blocks and some 4-gauge wire

You am is a monoblock amp, this is normal. The point behind it is there is no Left or Right, just Sub (which is usualy taken off the left channel). You are running 2 DVC 2Ohm subs, that means that you can wire it in different ways. If you wire each sub in parrallel, you will have a net resistance of 1Ohm per sub. From there if you wire the two subs in series, you will get 2 Ohms total for the amp. If you wire them in parrallel you will get 1/2Ohm. Most amps aren't stable below 1Ohm (and a lot aren't even stable at 1 Ohm) so running it at 1/2Ohm is out of the question. If you wire each sub in series, you will have a net of 4Ohms. And then if you wire the two subs in series you will have 8Ohms total or 2Ohms in parrallel. There is no possible way to get 1Ohm net into the amp (unless you only run 1 sub). The idea behind this is the same way as running "bridged" on a 2 channel amp.

so I have to get another amp? and just one of these amps aren't able to go down on 1 ohm but .5 ohm man that sucks

You can wire it like this... http://www.the12volt.com/caraudio/wo...s.asp?Q=2&I=22

You can use your amp, just base your calculations on a 2Ohm load instead of a 1Ohm load.

ohhhhh okay I gotcha SMAN... thanks a lot for your help! I still have to upload my pics I have another question would it be better to leave them in a sealed box or put them in a ported box?

That is a matter of greate debate, and it is often based on personal preference. Ported boxes will greatly alter the response curve. You can nearly double the output level between a specific frequency range, but you will loose it in others (based on the port tunning). A sealed box will give tigher response. There should be plenty of articles and posts about it at the12volt.com website.

here are the pics to the subwoofers, amp, and the box






did the wiring come out right?

I gotta find some push-buttton speaker terminals I don't like these spring terminals with the spades on the inside there too loose!
