i do not understand the whole impedence thing. From rumaging around on the net i understand you need a 2 ohm load for everything to run properly. I have currently been running a four ohm subwoofer on one amp, and now i would like to attached another one i bought(same sub) to the one amp. How will i wire these two four ohm subs to get the correct impedence.

The impedance that you need to "Run properly" depends on the amp you run, and the load at which it puts out its power. If yours puts out nice power at 2 ohms, you're in good shape... if you connect your two subs in parallel (Assuming they're single voice coil), you'll get a two ohm load. Connect + to + on the subs, and - to -, then connect this to the amp.

depends on the amp. everything varies.
subs come in 2 ohm, 4 ohm, and 8 ohm single coils.(usually) more custom spl subs can vary, 0.5 0.7 1.4 1.7 blah blah blah. but generally an amp will put out max power at a certain impedence. go to the rockford fosgate website to get a good diagram of how to wire subs properly to get the impedence your looking for.

Haha what a useful edit...
In most cases with car audio amplifiers, the lower the load, the more power you'll get out of the amp (to a certain extent). At 8 ohms, not many amps will do much power at all... 2 ohms seems like the surefire bet here, but it's best to know what the make and model of your amplifier is, just to be sure that two ohms is safe. If its a monoblock, chances are there shouldn't be a problem, since most are rated at one or two ohms. When you get into two-channel amps things are a little different.

There must be a model number somewhere... I'm not at all familiar with old RF stuff, or any old stuff in general I guess. I doubt you could go wrong if you hooked up one sub to each of the terminals on the amp. If its two channel, then each channel will see 4 ohms. If its a single channel amp and bridged internally, then it'd see a final impedance of 2 ohms, and I doubt either of these impedences would give you any trouble. See if you can find out the model though, then you could get a definite answer.
