1) In my old install, I replaced the back speakers with 5" MB Quart which I removed and are now sitting on my desk. Is it worthwhile to put those speakers into the Odessey or is that just a waste of time seeing how it is a new car with new speakers?
Keep the Quarts!
Understand that car manufacturers cut costs wherever humanly possible -- when you are talking volumes of hundreds of thousands of units, if you can save $10 on each car, that is a
monumental savings -- millions of dollars.
So when they can cut $40--$50 out of the expense of building the car by putting in speakers that cost them $6 apiece instead of $30 apiece, and affect the performance of the car so slightly that only a few lunatic audiophiles will even notice, they are going to do so.
Ask Paul Grzelak (pgrzelak) about how he likes his 'Quarts in his Buick. (You can read about it in a thread starting
here if you want more info.)
Now for the bad news... hang onto those MB Quarts because they are now collectors items. MB Quart has gone bankrupt and has been purchased by Rockford Fosgate. I don't want to step on anyone's toes here, but in my neck of the woods, at least, Rockford Fosgate is looked upon with considerable disdain (my stereo shop won't stock them, will special order them if a customer absolutely insists, but will give manufacturer warranty only instead of the shop's customary lifetime warranty on any product they sell and install) and I feel it is only a matter of time, and not much time at that, before Rockford Fosgate starts slapping the MB Quart labels on their own (IMHO) greatly inferior products and soon after that MB Quart will be only another forgotten name, proving once again that marketing will win out over quality.
