Hey Sam, did you have to cut yours?? I put 6.5inch Alpines in there and just used the spacer they supplied, no cutting required...
And with what Maci said, with the 6x9's, its not that much stuffing around, theres 4 tack welds that hold the plates in, you can literally hit them out with a hammer, might need a cold chisel on the last tack, just file the tack welds smooth once its out, thats how mine came out, no damage to the parcel shelf either...
