Sorry, I already did all the Math! LOL! It still came out to be about $70 cheaper for me to buy the whole system, then to buy all but the QS8's in the Factory Outlet. If I did that, I would not get the package discount. Now, the Sub maybe, However I think with my Modest Reciever Power, the 175 will work just fine for my needs. Again, this is my first system! Let me have a little room to upgrade! LOL! Thats half the fun! I have been doing car audio for 12 years, and my favorite part about getting a new car.. is not the car, but Mmmmm A new sound system! LOL! Well I will have this car for the next few years, so it was time to try a Home Audio system!!
