Hey I have 2 old style first generation audiobahn immortal 15s im looking to rebuild. Does anyone know of any specs that could help? Such as voice coil and spider size, who originally designed motor or what soft parts are compatible etc. I was told that a sundown nightshade drop-in would work but i would like advice and honest opinion from a knowledgeable subwoofer builder. Any feedback would be greatly appreciated, thanks

Try Dave at PSI, im pretty sure he could answer most of those questions for ya since he rebuilds subs for a lot of people.

How do I gta hold of em?
