\rThis is nearly impossible to answer, very subjective, and the prices differ quite drastically. However, the best subwoofer for your call will depend on the amplifier that you are using. If you have 300 watts RMS, a 600 watt RMS subwoofer is not the best subwoofer for you. If you truly have 1000 watts RMS, the best subwoofer for you will be a higher end model. Think of your subwoofer like a trailer and the amplifier as your truck. You don't want to try to pull a semi trailer with a 4 cylinder engine. At the same time, a 6.2L diesel engine isn't going to be ideal in a Honda Civic. The best subwoofer is one that meets your budget and that you can properly power with true, actual output, not 1000 watts because the box says it's 1000 watts.\r
