Hello Dave;  I bought a 100 watt powered sub-woofer at Wal Mart for $70 and
mounted it under the passenger seat.  I also bought a JVC CD, am,fm blah,
blah head unit.  It claims 35w per channel into 4 channels, it cost $175 or
so.  I'm really happy with the sound of the stock speakers, with this
combination. the head set brings the stock speakers to life.  The wiring
job is easy.         Larry Carter
