Hello All! I'm currently looking to upgrade my sound system. I'm looking for a good balance between loudness and sound quality. I have chosen some speakers and would like your opinion on them. Also, PLEASE if you know a better alternative to what I listed, don't hesitate to state. I'm relatively new to car audio, so I can use all the help you can over! My budget is around $600-$650 Here's some specs: Front doors: 6x9" Rear Doors: 6 1/2" Subwoofer: I'm looking for a single 12" sub woofer that sounds good but also has a nice punch. Here's what I found: Front Speakers: http://www.sonicelectronix.com/item_18905_Infinity-Reference-9632cf.html#tabs Rear Speakers: http://www.sonicelectronix.com/item_13963_Infinity-Kappa-62.9I.html Sub woofer: http://www.sonicelectronix.com/item_20027_Infinity-Kappa-120.9W.html#tabs ALSO, please suggest amplifiers. I have the most difficulty finding those and generally don't understand them. Thanks! Bealls
