I found mine at amazon.com

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 1: Amp is 2 channel and rated at 4Ω, 4 subs @ 4Ω each. If I connect two in parallel and the other two in parallel and connect the two pairs in series, I would have a total impedance(resistance) of 4Ω. So to the amp, it's just one sub.
Example 2: Amp is rated 1Ω mono, 2 subs @ 4Ω each dual voice coil. If I connect two voice coils in parallel and the other two voice coils in series and connect the two subs in parallel, I would have a total impedance of 1.6Ω. Which would be perfect for a 1Ω stable mono amp.
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
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.
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!!!
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.
Just e-mail me sparky3489@yahoo.com
My system
Blaupunkt TSw1200 subs with a Sony XplÅd 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

try:
http://www.crutchfield.com
Take a look at their subwoofer packages. You can get a pair of Alpine 12" subwoofers, subwoofer enclosure, and an Alpine amplifier for less than $400.00.

shipping on things like that is very high due to the weight, Go try some pawn shops or used electronics stores for good deals.
