The bostons sounded like ass? Well anyway on my car I had to use a plastick ring. I cant remember were I bought it! But when I do I will tell you were to get them! I had to move mine out 1" because I used 6.5" speakers! They look HUGE in my little civic doors! They take up about as much space as the word huge in that last sentance with the sentance being the rest of the door! Any way you can get them in lots of sizes! OH! BEST BUY! Thats were I got them! Door Speaker Spacers is what they are called! I think

Good luck dude, shoot me some pics when you are done!
BTW! TELL ME WERE YOU GOT THE BOOTY PIC! DAMMIT!~
