Planing on building an SQ system in my BMW 330Ci and thought of 3 MM840's.
I want all three woofers to play in one box.
Polk states 0.3 c.ft per woofer,but to my knowledge the total volume will be smaller if all three plays in the same enclosure.
Anyone know how big the box should be?
I'm thinking that 0.7 c.ft will be good..for some odd reason.:)
