Seems like this car audio stuff is addicting. People seem to upgrade their car audio gear quite often for bigger more powerful stuff. I think the setup I'm getting will be plenty for a while and I don't think I will want more. But what do you guys think? How long did it take you before you started upgrading your equipment? Why weren't you satisfied? How much is enough or is it ever enough? Personally I can't see myself going for 2000+ Watt systems and the like. I'm more of a sound quality person as oppose to high output. I'm wondering if my ears will be trained and get used to high quality and get hungry for more. How did your systems grow and why?
