Sub wiring Help!

I have everything figured out on how to put it in, other than how to hook my subs to my amp. I have a Pioneer PRS-D1100M amp, which does 600W RMS @ 2ohms, and 2 Alpine Type S, dual 4 ohms, 300W RMS each. How do I wire these suckers up? Series, parallel, individually? The wiring diagrams are just confusing me. Thanks guys.

you got the wrong subs. You need 2, 2 ohm dvc to get a total load of 2 ohms.
Trade them in.
OR, get another amp. put 1 on each sub.

I was told that this amp would do those subs perfectly. The specs say 400W RMS @ 4 ohm, and 600 @ 2 ohm. I was told to get the 4 ohm subs because you could wire them up to run 2 ohms.

How do I wire them to run at 2 ohms? I can take a picture of the system if you could draw some wires in with MS paint or something? My dad's the electrical guy, I'm just a bodyman

You should have gotten dual 2 ohm subs. you can only get 4ohm and 1ohm with two dual 4ohm subs.
Just bring them back to the shop, they should trade them in.

you can do it
http://www.the12volt.com/caraudio/woofer_configurations.asp

Option 1 (series/parallel) = 2 ohm load
Voice coils wired in series, speakers wired in parallel
Recommended Amplifier: Stable at 2 or 1 ohm mono

That would work but my subs are 4ohm DVC's. Would it make much difference to underdrive them by 100 watts RMS each? Sound quality etc? My amp will do 1 ohm stable but I can't remember the spec for the wattage @1 ohm.

My subs are non returnable because I got the floor models for about $100 off each. Should I just get a different amp?

Your subs are 100% an incorrect match to the amplifier. Take them back for a refund or trade towards subs that are matched to it. The subs to look at will both have single 4 ohm coils or 2 ohm dual coils, the latter being not too popular so find the single 4 ohm version. Failing that, take the amp back and find one that is either 4 ohm mono stable like the Pioneer PRSD2100T (same amount of power at 4 ohm as the PRSD1100M is at 2 ohm), or any 1 ohm mono amp if you want to keep the subs that you have now. Anyway you go about it, change the sub or change the amp. There is a smoking deal on the PRSD2000T right now, you can probably pick one up for under $400.00, that should be a sight lot cheaper than the amp you have now for the same amount of power and warranty. Only difference is that it is now a last years model.

you can do a 4oms or a 1oms set up both ways I WOULD NOT DO
1oms set up with put the info i would not do it
a 4oms just does not have the power
