anyone kinda know (ball park ) what the max depth speaker i can put in there? also what about tweeter size? im thinking some of the focal;s but i dont know which ones yet. im super happy with the focal coax's i ahve in my roll bars.

any info would really be appriciated.

 

2 inch max. any deeper and you will have to make a ring out of MDF

 

if you cut the "basket" off the back of the factory mounting ring, you shouldn't have a problem with most speakers.

which Focal's do you have currently? there are some good deals out there on the remaining stock of the 165 KF (Poly Kevlar line)...
