I hate manufacturers that put oversized speakers in doors. It is an EXTREMELY cheap solution regardless of who makes the system.What happens often with door speakers is moisture on the window (especially ones you roll down often) will drop onto the unshielded speaker, and eventually cause damage and deterioration.
This happened in my NB Miata (tiny car, but it had 8" door speakers) and I used a foam baffle to shield the back of the replacement woofers.
I have JBL in my Sienna and it has 6X9 in doors. Fine. Good sound to sell the new vehicle. The problem is when one likes loud music as I do, things are going to start to rattle eventually. Doors should see a maximum 4" mid-range speaker, and woofers would be elsewhere to limit rattles.
I have DIY woofers in BMW under seats in a place where BMW woofers were. 8" shallow Pionner woofers are much larger than 8" BMW Alpine or H&K that were used. But, still, no rattles regardless that I use 2X300W RMS amplifier on them.
In SIenna on other hand, everything rattles in doors.
