(2000 540iA version)
Well I've been looking for documentation on the DSP system ever since I ordered my car. No one was able to provide full pictures of the woofer enclosure. So I have now taken pictures of the enclosure and documented sizes for everyone to enjoy.
Two 5.25" Woofers (5 5/8" spacing diagonally between corner screw holes)
2 5/8" Deep (Max depth is 2.75") 4 3/8" Woofer Cone Diameter 5" Woofer Casing (width)
Dual Voice Coil 8 ohm per voice coil (gives you 4 speaker input sets)
Enclosure Manufacturer : NOKIA (Bandpass Type)
After removing the enclosure I measured that I can place a 32 5/8" wide x 16.5" tall custom sealed enclosure to fire through the armrest into the cabin. (I plan to place a 12" Square Kicker Solobaric into the enclosure I build)
(See Comments Between Pictures)
