    Driving what was my wife's 2008 Prius, and for the most part the sound is adequate but I have a bass rattle in the doors and I'm wondering what's the best way to resolve it.

    My source is my iPhone 6 via a Bluetooth add-on, and for the most part it is fine if i leave the iPhone volume level at Max minus 2-3 bars. But if the song is bass heavy and I have the JBL volume high, there is quite a bit of rattling vibration on the door (rattling panels, etc.), on all the doors.

    Q: Is this something that can be resolved by adding a sub and rolling off the bass for the JBL speakers? Or does resolving it require more a sound deadening at the doors?

    Also, people say there are 9 speakers, can someone tell me where they all are? For the life of me I only counted 7.

    BTW, I've searched through all the JBL threads and didn't see anything that's too helpful. Cheers.

    Sounds like a popped speaker. I have replaced 2 on my 2005 with JBL. I can't convince teen daughter to not turn bass and volume both up high.


    iPhone ?

    Yes either blown speaker or loose screw. Check if there is no hairpins in door pockets and take cool covers and check for bad speakers and hardware.

    There's always the possibility that the speaker is faithfully reproducing the white noise it's being instructed to.

    Woofer and tweeter in each door (8) and a center driver on the back of the MFD pointing at the windshield. Unless you have specifically located the noise in a door, this center speaker was loose and rattled on my car.

    or its just the cheap plastic door panels with very little dampening on them.

    for my '04, I bought spray on deadener and sprayed the insides of the door skins, and then applied duct insulation in place of the vapor barrier behind the door panels. it helped a lot. I need to do it to my '06 cause the lf door panel vibrates on certain notes. if I mash my knee against it the vibration stops.
