just got an orion 12 xtr pro..installed it in my 5th gen prelude...but theres this annnooyyying rattling coming from somwhere in my trunk. It actually sounds like its coming from the gas tank or underneath my car...but when i open my trunk lid it goes away. Even when i almost close the trunk, the rattling starts again. I put RAAMmat all over my trunk and theres still rattling! anyone have any ideas?! thanks

 

There are special BASS cd's you can get that might help! They go through all the bass frequencies, then you might be able to pinpoint were in your trunk the rattling is comming from Did you look at your tail lights? I had to take the panels off of mine! They rattled alot!

 

itside the tank, i feel like i have the same problem. but it doesnt bother me unless i stick my head under the car.
