I think its cool that you are doing what you can with what you have! I hope it surprises you on how loud it does on a meter. It's great to see people building their own stuff and being proud of it, and having a sense of accomplishment about it! You should be proud of it! I'm trying to do it myself as well, even though I'm a total noob. I have sound deadened the rear half of my truck and installed rear fill speakers so far, and for someone who hasn't done this before, I feel like I've got a great start. Keep at it bro, and good luck on the meter!!!!
