Crutchfield definitely has tons of info. along with great tech support. They also have really good sales every once in a while. I was able to get the Infinity Reference speakers (two-way 6.5 in the front and three-way 6X9) for $50 a pair. They even had the Infinity BassLink with the expansion card for $249. Too bad they were sold out by the time I decided to get one.
This might be old info., but I think the Boston Acoustics will not be as loud as the OEM's. Most OEM speakers are efficient, which makes them loud, but not as clear. Aftermarket speakers are usually clearer, but not very efficient. That's why an amp is always recommended to run them.
