ive seen people do it in sedans, and ive been playing with my backseat for awhile now. On the coupes it seems really hard to knock it out. I took the car to a local audio install shop and they said they didnt want to do it. So for anyone that has done it to a coupe, how did you do it, cause it looks like youd be cutting through metal to get free air from the trunk. thanks in advance.
