Hello! I am getting my 04 Grand Am GT Coupe in a little over a week. I am planning on getting subs for it. I want two 12s. However I am a noob at this car audio stuff. What are good brands and stuff subs/amps for two 12s? I have a Kenwood Head Unit if that makes a difference. My budget is $600 for everything. Some brands/series I have been looking at are the Kenwood performance series, Pioneer TS, SoundSolutionsAudio (SSA) DCON series (Leaning more towards this right now) and JL WXv2. I want deep, rich, loud bass. What box should I get too? Also, what are the difference between all of the boxes? Ported, sealed, etc.? The only amp I have really looked at is the Precision Power PPI P1000.1 from sonicelectronix. Thanks for any help!
