http://spkrbox1.spaces.msn.com/Default.aspx for real "sound" advice.
Your system won't mean squat without a well designed box to put your subs in. Some manufacturers have recommendations as to dimensions of various types of boxes. It is best to find someone who builds boxes if you go with something other than a sealed box.
You should always match up RMS (Root Mean Square) watts of Subs and amp per channel as well as impedance's(resistances).
If your amp is rated at 4Ω don't subject it to 2Ω, it will fry.
Here is the formula for subs in parallel:
Z = 1 / (1/sub1 + 1/sub2 + 1/sub3 + ....)
For series, just add them up (sub1 + sub2 + ...).
You can mix and match these equations to get the right impedance required by your amp.
Example: 4 subs @ 4Ω each. If I connect two in parallel and the other two in parallel and tie the two pairs in series, I would have a total impedance(resistance) of 4Ω. So to the amp, it's just one sub.
You should use a capacitor as well.
Recommend for every 500 watts MAX you use a .5 Farad cap
Example: 1000 watts MAX - 1 Farad cap
Try http://www.soundomain.com/shop you can find some really good deals, and this site is manufacturer certified. VERY IMPORTANT WHEN SHOPPING ON-LINE!!!
You will also need what's called a "line level converter" if your stock head unit doesn't have RCA outputs or your amp doesn't have high-level inputs.
If you like I can send you some plans for reference. My plans are for a 4-th order band pass bass box that holds two 12's. Also included are java calculators you can use to figure parallel and series values given Ω values.

My system
Blaupunkt TSw1200 subs with a Sony Xplōd XM2200GTX.
My amp is 1200 watts, subs are 600 watts each, cap is 1.2 Farad
SPL is about 112 db
Total cost(so far) = $410

at least an amp that gives off 600 watts rms power...

6-800 should be perfect but have it tuned

It all depends on how much ur subs can take.

i would say 600x2 would be perfect. those subs are good for sq too.
