Sorry . It's Vitz 2002, Chinese LCD bought for 7.5k installed and two front speakers factory ones. I bought 2000watt amplifier 4 channel(Rockmars company), JVC speakers(Rear ones) and Sony XPOD Single subwoofer. Bass is very loud. It's quite deafening. I need one with proper 4 channel(my front speaker not work with rear ones) crystal clear voice and punchy bass, not deafening one. Thanks
