Like title. Will there be any difference if using an aftermarket amp?
Where can I get a good deal on SWS?

Yes, if you have a one channel amp you will want to get 4 ohm subs and run them in parallel. If you get a two channel amp you will get the 2 ohm subs and run one to each channel. It all depends on what amp you get. You will want to get about 150rms to each sub. I will be using an Alpine MRP-M450 amp and running the 4 ohm subs in parallel to the single channel.

As for a good price....I just contacted audioonesaving on Ebay per this link and I just ordered 2 from them yesterday for $200.

I'm thinking of getting the Alpine PDX-5 which only has 1 channel for sub, but the spec says it can support both 2 and 4 ohm speaker, so that's y I posted.

You'll be using one channel and dirving the subs in parallel. Thus, if you use 2 SWSs 4ohm you'll make the amp work at 2ohm (because of the parallel diagram). If you use 2 SWSs 2ohm you'll make the amp work at 1ohm (for the same reason).

You don't want to make the PDX work at 1ohm, but you can make it work at 2ohm.

2 SWSs 4ohm is your way

cool, thanks for all your replies. I think I'll get the 4 ohms, but out of curiosity, would it be the same if I run 2 2ohm in series VS. 2 4ohm in parallel? or is running them in series is not a good idea?
