? do i drill a 12inch hole on my cabinet for my 12inch speaker or do i actually need to drill something smaller? I think i messed up, i drilled one 12inch hole dam . . .
umm well in electrical work i know if it says its 20 mm u use a 20 mm bit its usually compensated for.
woo thats some great news, i kind of freak out when i measure my mg hole. The hole is actually 6.5inch but the speaker is suppose to be 8
You should probably be right, most speaker holes I've ever made have been 5mm smaller in diameter than the speaker cone diameter. You should have checked on the speaker data sheet before you made the hole.
