Thanks a million LightninSVT, I thought you had not read my post. Will get to building my box soon.

 

No problem man, good luck with everything.

 

Hey I know this is old but are u able to move your center console with that 3rd speaker in the middle like that. Thanks

 

Damn thats gorgeous! Nice job.

If its that easy to make a box fit then I wonder why JL Audio decided not to make a steathbox for the lightning.

BTW. How do those sound?
