I was really getting sick of hearing the rattle of the back deck every time a song with some bass came on the radio. I'm planning on wrapping everything in some type of sound deadening but wanted to get all new clips and the material ahead of time. So Sunday morning I climbed in the trunk with my flash light. I could see the oval openings that are towards the rear of the deck and I removed the trunk light which reviled better access to another opening. I cut up some 2" x 4" pieces of a microfiber rag and started stuffing those pieces in the holes toward the front of the car and to each side of the openings. After stuffing as much as I could I finished by stuffing pieces towards the rear of the car. I could only get one piece in each hole towards the back of the vehicle. I then went to the Hip Hop station on XM and I'll be damn if the rattle stopped. I have the bass set at 2 bars from full and the subwoofer set at 2 bars from full. Why in the heck Honda couldn't do this when building the damn car I have no idea...lol... I still want to pull the deck out and do it right but for now the system sound pretty damn good on XM or IPod.
