Agree about the warranty. But I would suggest you not take advise on car audio from this forum. As you can see, Hotpotato has spent a huge sum of money based upon a lack of knowledge. You would be better served to find a good car audio store or two and get their advise. The alternative is to read a ton on the car audio forums to learn, but it's a steep learning curve and not worth it unless you are really into building your own system. I managed a car audio store out of college and have built many systems for my own cars. Yes, they all sounded good in the end but often were just too much trouble for the result. For example, HotPotato says he hears his sub down to 20hz. That's physically impossible due to the size of the wavelength. I can't hear it in my home, at best, I can hear down to maybe 30hz, but with a system playing down to just 40hz you would have great sound. You also can't hope to equalize a system by ear-you need a spectrum analyzer to set to a proper curve. From there you can tweak it. I have the Sony upgraded system, and with 100watts it has sufficient power for normal listening. It needs a sub and an equalizer to sound good. The speakers are decent enough. If there is a way to obtain low level signals to add these, you would have very good sound w/o spending a lot of unnecessary money. Just my opinion.
