The title says that. At least, that's the way "dual" is normally used... but I couldn't verify the subs because I couldn't find them at the Alpine site.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

The SWE-1241's are a SVC 4 ohm sub.

I think what Xtreamcc and I thought was that when he said he needed two 4 ohm subs bridged on an amp at 4 ohms....somehow, that he just had two 4 ohm SVC's.

So, new testimony. My same argument above applies to this

Dual 4ohm to 4ohm load? - Page 2 -- posted image.

Same as 4 ohm stereo, neater install.

I dont understand how it is the same as 4 ohm stereo when it is bridged at 8 ohms? Wouldn't that create more of a problem than when I had it 2 ohm bridged and have even less power going to my subs? I understand the series part of the wireing I just don't know why I would do it in this case.

Bridging is the act of connecting two amplifiers. A two channel amp is in fact two mono amps. The load, when bridged, goes half to one amp and half to the other amp...so a 2 channel amp gets 4 ohm per channel in this case. The reasons I would bridge instead of connecting each sub to a channel are listed in my first post:

Take the overall install into consideration...the subs share the same enclosure, and sub freqs do not need to be played in stereo. Both of these points go to the bridged way of thinking. Also, there will be less speaker wires to hide, a point also going to the bridged argument.

Another reason that sometimes applies is that you will get a more impactful bass response if both subs are getting the same mono input, rather than one getting left and the other getting right signals.
