Im beyond frustrated and have turned to my scion friends for help. i have an AvicD3, 2 kicker comps and a 400w clarion amp, and monster wiring. until recently it has never done this but now whenever i hit a bump or the cars body position changes the subs hit, even with no music and the hu turned off. its starting to you know what me off. . ive checked the wires and theres no breaks in the housing touching the frame or anything, no magnets close to them, only thing i can think of is the little bit of slack i have in my wires (like 6-8" of play). i had the slack tucked away in the rear cargo area (under my subs), but just pulled some of the slack out to see if they were too close to the amp. im going to give that a try and report back...just very frustrating.

thanks for any help.

 

my guess would be to check your ground.

 

If the sub is hit when you go over bumps & you have a good ground.. Bad news sub is bad recoil.. sorry I had same problem....

 

I will go check the ground first also

 

Make sure the door speakers haven't come loose. My old ford escort had the same problem. When I would make right turns the speaker got loose and hit the door and the music went out but my subs still hit. I just had to tighten the screws. I know they're different cars but it's worth a shot.
