Check out the specs here: www.pioneerelectronics.com/Pioneer/CDA/CarProducts/ CarProductDetails/0,1429,250,00.html I also have the matching SW-100 100W subwoofer for this, if you want it. 12" driver, 80-120HZ variable crossover, level control, auto on, stereo RCA inputs and speaker level inputs and outputs. It shakes the room with the crossover at 80Hz and the level one notch above zero. Price for the 5 speakers is less than half, $250. I'm selling these since I'm moving, and will probably get smaller ones later. Subwoofer was $399-499 retail, $150 takes it. I'm in the Denver, CO area, but am willing to ship these if necessary. Email me at [email protected] with questions or if you're interested. Thanks for looking.
