Can my alpine mrp-m500 hook up too two subwoofers?

you could run 4 subs or even more if they are wired right. you just divide the power between however many speakers are connected. you want your final ohm load to be 2 ohms. so if you have 2 single voice coil (SVC) 4 ohm subs, it will equal 2 ohm. perfect. 250 watts RMS each sub. If you buy dual voice coil (DVC) subs, you will need dual 2 ohm subs to come out to a 2 ohm final ohm load. wiring info can be found here : a href="http://www.crutchfield.com/learn/learningcenter/car/subwoofers_wiring.html" rel="nofollow"http://www.crutchfield.com/learn/learnin…/a
