ok, you have one sub. Is it a 4 ohm ? It should say on the box or manual if your're not sure what this means. If this is the case, you should purchase an amp that says something like "300w max" or even as low as "250w max". I would go with 300, no more than 400max. 600 is usually just an exagerrated number that the companies come up with. If you put 600 watts into your sub, you would more than likely blow it. Further more, yes you would bridge your sub, having only one. Make sure when buying an amp, it says "bridgeable". Im pushin my two 400w subs with two 100w amps at 4 ohms. It sounds pretty darn good. well, good luck!
...it will be mine, oh yes, it will be mine...
