I commented on it in there. It shouldn't be too much... The door panels are light, they're 3/4" plywood with a solid wood strip on the top. I mean, maybe twice what the carpet and cardboard stock panels weigh but whooptie doo an extra pound. In the trunk there's 1/2" ply under half inch cherry hardwood so it's pretty heavy, the sub box was built to be lightweight so it's not too bad, the amp rack is fairly heavy with the amp mounted. But then keep in mind I lost the spare tire and jack, and the carpet and hardboard under the carpet too so I'm guessing it's not far off a draw there. *Maybe* 10lbs extra at the most overall over and above a stock car. The sound deadening I added is probably 25 lbs, though so I'm maybe 35 or so over stock then. Not enough for me to worry about it. I was 3317lbs with me and a half tank at mission last summer so I'll be maybe 3350lbs now, meh, I've got water injection to make up the difference now, haha.
