Okay, so I'm buying a "Polk Audio PSW505 12-Inch Powered Subwoofer" and "Micca Motion Series MB42 Bookshelf Speakers With 4-Inch Carbon Fiber Woofer and Silk Dome Tweeter" and I need to know how to connect these all together. The subwoofer is 460 watts and has a built in amp but the speakers are only 100 watts and don't have an amp and I'm afraid that I'll blow up my speakers if I plug them into the subwoofer. Do I need to buy a separate amp for the speakers and if so how do I plug these into my subwoofer with 2 amps? I am going to be running these speakers and subwoofer off of my iPod, will it be powerful enough? I have absolutely no idea what I'm doing...:confused:... The links below are of the subwoofer and speakers.
