BOSS BRS40 4" Dual Cone Replacement Speaker
Just picked up a pair of these and cannot find any specifications for determining optimum cabinet size and porting info. I know they're cheapies, but can someone give me an approximation for cabinet size and porting?
Due to how these are packaged we cannot pull one from stock to measure T/S parameters, and Boss does not supply them. Speakers like this will have an Fs around 100 Hz and a high Qts since they are generally designed for IB applications, so a sealed box will yield the smoothest bass response. A volume from 0.2-0.4 should work fine, but you won't get much below about 80 Hz from them.

Hello, can you give me the mounting dimensions..
The overall diameter (side to side) of the frame on this is exactly 4". It requires a 3-7/8" diameter cutout. The mounting holes are 4-1/2" across diagonally, 3-1/4" measured adjacently and it is 1.7" deep.

do you have a speaker like this in a 2" or 3" version?
We have plenty of 2 or 3" full range speakers available, but the smallest option we have in the car audio section is the 3-1/2" GRS below.http://www.parts-express.com/grs-3as-4-3-1-2-dual-cone-replacement-car-speaker-4-ohm--292-452

I want to use this to update and restore an old drive in speaker. I need to send the signal through a potentiometer (volume control knob). What rated potentiometer should I use for the best sound?
You need to use an "L Pad" to control the volume of the speaker.They are available from P.E.

I am replacing speakers in a 97' Trans-Am and need the mount pattern dimensions for these speakers to compare to the ones currently are in my car. Is that possible? Thank you!
The bolt holes are on a 4-1/2" circle.
