yea, thanks for the info about the amps. I do like the DD's, but one of my friends has them already, and i was looking for something different. I can get the Audiobahns for 355 each anyway, which is actually cheaper, but the amps to power them will be quite expensive. You are right, i have looked into the JBL amps, but it was also questionable, since it is soo cheap. If its only 300, the factory is doing something right, because with all of the bad comments about the boss, it is 800. I will look into the JBL amps though. Any comments about that would be appreciated. I was planning on buying a 5-farad Audiobahn Capacitor and a new yellow top battery, just for the system (excluding car operations). Do you think i would need a higher amp alternator still after i get the cap, and the battery? The cap should store up enough power to keep the stock alternator. Just let me know what you think about the JBL amps, and the subs also if anyone has any comments about them.
