I've got a new Pioneer DEH-4700MP which I love (Wal-Mart=$168.00+tax), which is currently running only basic Pioneer 2-way 6x9's and minor upgraded door speakers. Heard great things, and read good stuff, so I'll DEFINITELY be buying Infinity Reference 6903i 6x9 3-ways and building hatch box for them myself. Also plan to get Kenwood KAC-8402 60wx4, or Sony XM-4060GTX 60x4 amp to run front/rear w/o sub. I'm looking for strong, rich, clean, crisp, and LOUD sound, w/o too much thump, or rattle. I could live with what I've got, but I'll stay with what I get, then....on to better security mods!
