Illusion Audio Carbon C8 adapters

[Impala_98]

I'm thinking of putting a set of these in my front doors. Does anyone know if there are adapters available for 8" speakers in the front doors or know where I can get some made. I currently have some Infinity Kappa 693.11i 6x9s installed

Only alpine makes a bolt in adapter and they won't sell just the adapter. It comes in the gm31 kit. So you'll have to make you own or have some made
