Need help. I'm considering mounting POLK DB6750 components up front.....

Mounting depth is 2 3/8... will I clear the window? without a spacer...

Woofer is 6.75 versus the popular 6.5 (DB6500) will it fit on the Platic speaker plate? after cutting

I know Darious runs the DB6500 (2.0 depth) and Banana GS runs the DB5250s..

Thanks...
