cutting slot in rear deck
hello everyone,
i have an 2008 e90 that i just added 2 jl audio 10w3v3 with and alpine pdx 600w amp. i notice that the bass is really muffled pretty well by the rear seat, and i don't have the ski hole pass through, but i have a carseat installed, so that wouldn't help anyway. so, i was looking at ways to "vent" bass into the trunk somehow, and i noticed there is like a slot in the metal right under the rear deck in between the 2 rear speakers. i felt my hand up in there and i felt the top of the rear deck. so, does anyone know if i cut a rectangular slot in the rear deck, would that make a significant difference in bass output coming from the trunk? has anyone cut the rear deck to allow bass to come out of the trunk? or is this more scientific than cutting a slot, similar to tuning a port when you have a ported sub box, and you would have to determine port length and width to "tune" it to a certain frequency? thanks.
