OK, first of all... I KNOW NOTHING ABOUT SUBS/AMPS OR ANYTHING ELSE TO DO WITH CAR AUDIO I just got a 2004 Mazda6 w/o the Bose stereo system, so I am looking to add some subs to it. I have been looking for a couple, days. I am pretty set on getting either Rockford Fosgate or Audiobahn. I am looking to spend quite a bit of money, because I really want a good setup, but I still want it to be reasonable. I was looking at this subs w/ enclosure: Audiobahn ABP12T http://www.sounddomain.com/sku/ABNABP12T - These are the 12" Audiobahn ABP10T http://www.sounddomain.com/sku/ABNABP10T - These are the 10" -- I needed to know how big of an amp I would need to power these, and I really would like to stay with audiobahn for the amp also. The amp will just be powering the 2 subs in the box and nothing else. Please post any information or suggestions that you have.
