the'll fit in a jeep. I bought mine out of one.
they are two piece cabinets. big boxes...but thei'll fit in a jeep.
swapping the tweeters is a good sign. that means you have newer ones than otherwise.
I plan to swap out all of the drivers in mine. I can hear one of my sub-whoofer drivers is on the way out. it "cracks" on a few recordings.
at VSA, they upgrade the vr4 to the vr4.5. this replaces all of the drivers. mid range, whoofer and sub. they take the old vr4 stock drivers and put them in inventory. so they have shitloads of them.
its only $50 per cone too. hey...what the hell.
